2SA1267 Transistor - Features & Typical Applications
The 2SA1267 is a popular PNP bipolar junction transistor (BJT) well-suited for low to medium power switching, general amplification, and analog signal processing in consumer and industrial electronics. Its compact TO-92 package and predictable gain make it a common choice among South African makers, students, and service technicians.
Where Is the 2SA1267 Used?
- Audio preamps, tone controls, and small amplifier stages
- Analog switching in control circuits and relay drivers
- Signal processing and repair of classic Japanese audio/tuner equipment
- Tinkerers and tertiary electronics courses covering basic BJT operation
| Parameter | 2SA1267 Typical Spec | Common Use Case |
|---|---|---|
| Polarity | PNP | Low-side switching, amplifier driver |
| Vce Max | -50V | Direct mains signal path (with protection) |
| Ic Max | 0.15A | Small relay/signal driving |
| hFE (Gain) | 100-400 | Preamp & switching circuits |
| Package | TO-92 | Breadboards & PCB prototyping |
Why Buy 2SA1267 from Communica?

Compatibility & Alternatives
The 2SA1267 is widely compatible with other small-signal PNP BJTs with similar voltage and current ratings (e.g., 2N2907, BC327 for lower voltage), but always verify hFE and pinout in your application or repair context. Check datasheets before substitution.
Breadboarders and industry users benefit from Communica's branch collections in Samrand, Pretoria CBD, and Cape Town, avoiding international shipping delays and import VAT hassles.

Specifying the Right 2SA1267 (Selection Guide)
- Confirm pinout: TO-92 (E-B-C inline layout; check with continuity meter before soldering)
- Ensure voltage & current match: -50V, 0.15A maximum (suitable for most low signal circuits, not high-power)
- Check gain (hFE) grade if circuit requires: standard is 100-400 @ 2mA Ic
- Assess possible higher-temperature ratings for industrial sites (up to 150 degreesC junction typical)
Common Applications - South African Scenarios
- Repairs: Fixing legacy amplifiers found in many schools or churches, often using 2SA1267 as preamp/switching stage
- Student Labs: Universal BJT labs, transistor class demos, design-and-test exercises on perfboard
- Maker/Hobby Projects: Audio buffers, oscillators, control signal inversion, simple relay drivers
Accessory Bundles and Related Stock
- Recommended breadboard kits, resistors for biasing, and TO-92 sockets available in the All Products category
- Find oscillator ICs, relay modules, and enclosures to round out your prototyping BOM
Fast Procurement & Support
- Instant online stock check and transparent lead times on product pages
- VAT invoicing for companies, schools, and universities
- Account solutions for recurring bulk buyers (contact for eligibility)
To use the 2SA1267 as an on-off switch for a 12V relay (40mA coil):
Choose base resistor RB:
RB = (Vin - VBE) / (IC / hFE) = (5V - 0.7V) / (0.04A/150) ~ 16.1kOhm (use nearest standard value)
Troubleshooting & Tips
- Check for counterfeit/remarked transistors when buying abroad - Communica sources direct from vetted suppliers
- Observe correct pin orientation (emitter/collector inversion is a common project pitfall)
- Replace in pairs for audio applications to preserve balance and noise performance
