Matched pair transistors

Our new matched pair transistors ensure accurate base-emitter voltage (V_BE1 / V_BE2) and current gain (h_FE1 / h_FE2) matching and are fully internally isolated. As a replacement for standard double transistors in current mirror and differential amplifier applications, they eliminate the need for further costly trimming. They can also be used with an additional single or double transistor to deliver operational amplifier functionality at minimal product cost.

Key features

• Current gain matching to 10, 5 or 2%
• Base-emitter voltage matching to 2 mV
• Choice of standard double transistor pinout or application-optimized pinout
• Common-emitter configuration for 5-pin type
• Range of small, very small and ultra-small packages

Key benefits

• Improved performance of current mirror and differential amplifier circuits
• Drop-in replacement for standard double transistors (BCM series)
• Simplified board layout (PMP series)
• Eliminates the need for costly additional trimming

Key applications

• Current mirrors
• Differential and instrumentation amplifiers
• Logarithmic amplifiers
• Comparators
