Nexperia USA Inc. BC807-25,215

Overview

BC807-25,215 from Nexperia is a PNP bipolar junction transistor (BJT) in SOT23 (TO-236AB) package, rated for −45 V V_CEO, −500 mA continuous collector current, and DC current gain (h_FE) of 160–400 at V_CE = −1 V and I_C = −100 mA. It serves as a general-purpose switching and amplification device in low-voltage power management and signal conditioning circuits.

For engineers reviewing the BC807-25,215 datasheet, BC807-25,215 pinout, BC807-25,215 application, or BC807-25,215 equivalent, key selection criteria include verified h_FE range, thermal resistance (362 K/W with 1 cm² collector pad), V_CEsat ≤ −700 mV at I_C = −500 mA/I_B = −50 mA, and SOT23 footprint compatibility with automated assembly.

Technical Context

This PNP transistor operates in active and saturation regions with defined breakdown limits: V_CBO = −50 V, V_CEO = −45 V, and V_EBO = −5 V. Its pulsed operation supports I_CM = −1 A (t_p ≤ 1 ms) and I_BM = −200 mA, enabling robust transient handling in digital logic interfaces and relay drivers.

Thermal performance is characterized by R_th(j-a) = 362 K/W when mounted on FR4 PCB with 1 cm² collector copper pad, and transition frequency f_T = 80 MHz at V_CE = −5 V, I_C = −10 mA, confirming suitability for audio-frequency amplification and medium-speed switching up to ~10 MHz.

FAQ

What is the maximum continuous collector current for BC807-25,215?

The BC807-25,215 is rated for −500 mA continuous collector current at T_amb = 25 °C with proper PCB thermal relief. Derating applies above 25 °C ambient per the 362 K/W thermal resistance curve; at 70 °C ambient, maximum usable I_C drops to approximately −350 mA to maintain T_j ≤ 150 °C.

How does the h_FE of BC807-25,215 compare to BC807-40?

BC807-25,215 has a guaranteed h_FE range of 160–400 at V_CE = −1 V and I_C = −100 mA, whereas BC807-40 specifies 250–600 under identical conditions. The higher minimum gain of BC807-40 reduces required base drive in low-current applications, but BC807-25 offers better gain uniformity across the mid-range and tighter distribution for production-critical biasing.

Can BC807-25,215 be used in place of BC807-16?

Yes, BC807-25,215 can replace BC807-16 in most circuits because its minimum h_FE (160) exceeds BC807-16's maximum (250), ensuring sufficient gain margin. However, in precision analog circuits relying on specific h_FE feedback ratios, verify loop stability and offset behavior-especially where BC807-16's lower gain was intentionally selected to limit amplification.

What is the recommended base resistor value for switching a 300 mA load with BC807-25,215?

For reliable saturation at I_C = −300 mA, use I_B ≥ −30 mA (assuming forced β = 10). With a 3.3 V MCU GPIO driving the base through a resistor to emitter (V_BE ≈ −0.85 V), R_B = (3.3 V − 0.85 V) / 30 mA ≈ 82 Ω. A standard 82 Ω ±5% resistor ensures ≥30 mA base current across voltage and temperature variation.
