onsemi BC32716TA

Overview

BC32716TA from ON Semiconductor is a PNP epitaxial silicon transistor designed for low-power switching and amplification, with h_FE of 100–250 at I_C = −100 mA, V_CE = −1 V, V_CEO = −45 V, and P_D = 625 mW in TO-92 package. It serves as a complement to BC337/BC338 in audio driver stages and low-power output circuits.

For engineers reviewing the BC32716TA datasheet, pinout, applications, or equivalent options, key selection considerations include its guaranteed h_FE range, −45 V V_CEO, TO-92 thermal resistance (200 °C/W), saturation voltage (−0.7 V at I_C = −500 mA), and suitability for discrete biasing and signal inversion in cost-sensitive consumer and industrial controls.

Technical Context

This device operates as a general-purpose PNP bipolar junction transistor with fixed gain classification (h_FE = 100–250), rated for continuous collector current up to −800 mA and junction temperature up to 150 °C. Its breakdown ratings (V_CEO = −45 V, V_CES = −50 V) and low V_BE(on) (−1.2 V at I_C = −300 mA) support reliable operation in linear and saturated switching modes.

The BC32716TA uses standard TO-92 leadframe construction with defined pinout (1: Collector, 2: Base, 3: Emitter) and exhibits f_T = 100 MHz at V_CE = −5 V, I_C = −10 mA, enabling use in low-frequency amplification and AF signal paths up to several megahertz.

FAQ

What is the h_FE range specified for BC32716TA?

The BC32716TA has a guaranteed DC current gain (h_FE) range of 100 to 250 when measured at V_CE = −1 V and I_C = −100 mA. This binning ensures predictable biasing in amplifier and switching circuits. The h_FE value is confirmed per the official ON Semiconductor BC327 datasheet Rev. 1.1.0 and applies specifically to the BC32716TA variant.

Is BC32716TA pin-compatible with BC337?

No, BC32716TA is not pin-compatible with BC337 because they are complementary devices (PNP vs. NPN) with identical TO-92 pinout (1: C, 2: B, 3: E), but opposite polarity and biasing requirements. Circuit redesign is needed when substituting BC32716TA for BC337. The BC32716TA datasheet confirms its pin assignment matches the standard TO-92 layout shared across the BC327 family.

What is the maximum collector current rating for BC32716TA?

The absolute maximum continuous collector current (I_C) for BC32716TA is −800 mA at T_A = 25 °C. Derating applies above ambient temperature, and actual usable current depends on thermal design and V_CE conditions. This rating is explicitly stated in the Absolute Maximum Ratings table of the BC32716TA datasheet and verified across ON Semiconductor's official documentation.

Does BC32716TA support surface-mount assembly?

BC32716TA is supplied in TO-92 package with through-hole leads and is not a surface-mount device. However, its ammo-packaged form (as indicated by the "TA" suffix) supports automated insertion equipment. The BC32716TA pinout and mechanical dimensions align with JEDEC TO-92 standards, enabling compatibility with standard wave-solder and selective soldering processes-not reflow.

What is the thermal resistance (R_θJA) of BC32716TA?

The junction-to-ambient thermal resistance (R_θJA) of BC32716TA is 200 °C/W under standard test conditions (FR-4 PCB, 76 mm × 114 mm, minimum land pattern). This value guides heatsink sizing and board layout for power dissipation up to 625 mW. It is published in the Thermal Characteristics section of the BC32716TA datasheet and applies identically across all BC327 variants in TO-92.
