Product details

Overview

BCX5316H6327XTSA1 from Infineon Technologies is a PNP silicon bipolar junction transistor designed for audio frequency driver and output stages in linear and switching applications. It features V_CEO = 80 V, I_C = 1 A continuous, V_CE(sat) ≤ 0.5 V at I_C = 500 mA / I_B = 50 mA, h_FE = 100–250 (at I_C = 150 mA), and SOT-89 surface-mount package. It is used in automotive body control modules for relay and lamp driving.

For engineers reviewing the BCX5316H6327XTSA1 datasheet, BCX5316H6327XTSA1 pinout, BCX5316H6327XTSA1 application, or BCX5316H6327XTSA1 equivalent, key selection criteria include guaranteed h_FE range at high I_C, low V_CE(sat) under 500 mA load, thermal resistance R_thJS ≤ 15 K/W, AEC-Q101 qualification, and complementary NPN pairing with BCX56-16.

Technical Context

This PNP BJT operates in active, saturation, and cutoff regions with DC current gain specified across three test conditions: h_FE ≥ 100 at I_C = 150 mA (BCX53-16 grade), ≥ 160 at I_C = 500 mA, and ≥ 250 at I_C = 5 mA. Its f_T = 125 MHz enables stable operation up to mid-VHF frequencies in oscillator and RF buffer roles.

The device supports pulsed collector currents up to 1.5 A (t_p ≤ 10 ms) and maintains V_(BR)CEO = 80 V and V_(BR)CBO = 100 V at I_C = 10 mA and 100 µA respectively. Thermal derating begins at T_S = 120 °C, with P_tot = 2 W at T_S ≤ 120 °C and R_thJS ≤ 15 K/W.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP switching transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BCX53-16,115 (Nexperia)	Same V_CEO = 80 V, h_FE = 100–250, but R_thJS = 18 K/W (vs. Infineon's ≤15 K/W); no AEC-Q101 documentation provided	Not qualified for automotive under-hood use; suitable for industrial control where thermal margin is relaxed	Select when cost sensitivity outweighs thermal performance and automotive qualification requirements
MJD2955G (ON Semiconductor)	Higher P_tot = 15 W, TO-220 package, V_CEO = 60 V (lower than BCX5316's 80 V); h_FE = 20–70 at I_C = 4 A	Requires heatsink; suited for high-power linear regulation, not space-constrained SMT designs	Select only when >1 A continuous current and forced-air cooling are available

Compared with BCX53-16,115 and MJD2955G, BCX5316H6327XTSA1 uniquely combines AEC-Q101 qualification, 80 V breakdown, ≤15 K/W thermal resistance, and SOT-89 footprint-enabling compact, thermally robust, automotive-grade switching without external heatsinking.

FAQ

Is BCX5316H6327XTSA1 pin-compatible with BCX53-16 from other manufacturers?

Yes-BCX5316H6327XTSA1 uses the standard SOT-89 package with pin 1 = Emitter, pin 2 = Collector, pin 3 = Base. This matches the JEDEC MO-220 footprint and mechanical layout of all BCX53-16 variants, including Nexperia and ON Semiconductor equivalents. No PCB redesign is required for drop-in replacement.

What is the maximum allowable base current for continuous operation?

The absolute maximum rated base current is I_B = 100 mA per datasheet. For reliable continuous operation, design base drive to maintain I_B ≤ 50 mA, ensuring h_FE remains within specification and preventing localized heating at the base-emitter junction.

Does BCX5316H6327XTSA1 support operation at −40 °C ambient?

Yes-its specified storage temperature range is −65 °C to +150 °C, and electrical characteristics are guaranteed from −55 °C to +150 °C junction temperature. At −40 °C ambient with typical PCB thermal resistance, it operates fully within spec for automotive body electronics applications.

Can this transistor be used in a complementary pair with BCX56-16?

Yes-BCX5316H6327XTSA1 (PNP) and BCX56-16 (NPN) share matched V_CEO/V_CBO, h_FE grading, and SOT-89 package. Their complementary characteristics are explicitly documented in Infineon's BCX51–BCX56 datasheet for Class-B and push-pull amplifier designs.
