Product details
Overview
BCX52-16E6327 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 60 V VCEO, 1 A continuous collector current, 0.5 V typical VCE(sat) at IC = 500 mA / IB = 50 mA, hFE of 100–250 (at IC = 150 mA), and SOT-89 surface-mount package - used in automotive body control modules and industrial power regulators.
For engineers reviewing the BCX52-16E6327 datasheet, BCX52-16E6327 pinout, BCX52-16E6327 application, or BCX52-16E6327 equivalent, key selection criteria include verified VCEO/VCBO ratings, hFE consistency across IC range, thermal resistance RthJS ≤ 15 K/W, and RoHS-compliant SOT-89 mechanical compatibility with PCB layout constraints.
Technical Context
This PNP BJT operates in active, saturation, and cutoff regions with defined DC gain linearity (hFE = 100–250 at IC = 150 mA, VCE = 2 V) and low-saturation performance (VCE(sat) ≤ 0.5 V). Its fT of 125 MHz supports stable AF amplification up to ~10 MHz with minimal phase shift.
Thermal design relies on its SOT-89 package's RthJS ≤ 15 K/W and Ptot = 2 W at TS ≤ 120 °C, enabling direct heatsink mounting without thermal vias in medium-power linear regulators and relay drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 60 V - maximum safe collector-emitter voltage before breakdown in common-emitter configuration |
| IC (continuous) | 1 A - rated DC collector current for sustained operation without derating at TS ≤ 120 °C |
| VCE(sat) | ≤ 0.5 V at IC = 500 mA, IB = 50 mA - ensures < 0.25 W conduction loss in saturated switch mode |
| hFE | 100–250 at IC = 150 mA, VCE = 2 V - enables predictable base drive sizing for linear amplification |
| fT | 125 MHz - supports stable small-signal gain up to 10 MHz with ≤ 3 dB roll-off |
| RthJS | ≤ 15 K/W - allows direct thermal path from junction to solder point for board-level heatsinking |
| Ptot | 2 W at TS ≤ 120 °C - defines maximum power dissipation under controlled board temperature conditions |
Pinout & Package
SOT-89 package: 3-pin, surface-mount, molded plastic case with exposed emitter pad for thermal enhancement and mechanical stability. Pin 1 = Base, Pin 2 = Collector, Pin 3 = Emitter - confirmed per Infineon package outline EHP00437 and marking layout documentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Base) | Current-controlled input node | Accepts 50 mA peak base drive to saturate 500 mA collector load; requires series resistor for current limiting |
| 2 (Collector) | High-side current sink terminal | Connected to positive rail in high-side switch topology; handles full load current with minimal voltage drop |
| 3 (Emitter) | Reference and thermal anchor node | Common return path; exposed pad provides primary thermal conduction path to PCB copper |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) | ≤ 0.5 V at IC = 500 mA - reduces conduction losses by >40% vs. standard PNP transistors in 12 V relay drivers |
| AEC-Q101 qualified | Qualified for automotive electronics per stress test requirements - suitable for under-hood body control units |
| RoHS-compliant packaging | Pb-free SOT-89 construction - meets EU Directive 2011/65/EU without exemptions |
| Complementary NPN pairing | Designed as PNP counterpart to BCX54–BCX56 series - enables matched push-pull output stages |
Applications
| Automotive Body Control Module | Industrial Linear Regulator |
|---|---|
Use Scenario: Driving 12 V solenoids and LED clusters in door lock and lighting subsystems. IC Role / Device Role / Timing Role: PNP switch controlling high-side load current with fast turn-on/turn-off via base drive. Use Value: 0.5 V VCE(sat) limits power loss to 250 mW at 500 mA, reducing thermal stress in sealed enclosures. | Use Scenario: Pass element in adjustable 5–24 V linear regulator for sensor signal conditioning circuits. IC Role / Device Role / Timing Role: Series pass transistor regulating output voltage via feedback-controlled base bias. Use Value: hFE ≥ 100 ensures stable regulation with < 1% load regulation error across 10 mA–1 A output range. |
| Audio Power Amplifier Stage | DC Motor Speed Controller |
Use Scenario: Complementary Class-B output stage in 1–5 W audio amplifiers for infotainment systems. IC Role / Device Role / Timing Role: PNP half of push-pull pair delivering negative half-cycle current to speaker load. Use Value: fT = 125 MHz maintains flat frequency response to 20 kHz with < 0.5° phase shift at 10 kHz. | Use Scenario: H-bridge high-side switch controlling bidirectional 24 V DC motors in HVAC actuators. IC Role / Device Role / Timing Role: High-side PNP switch enabling PWM-based speed control with dead-time management. Use Value: VCEO = 60 V provides 150% margin over 24 V rail, preventing avalanche failure during inductive kickback. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCX52-16,115 (Nexperia) | Same VCEO (60 V), hFE 100–250, but RthJS = 18 K/W vs. 15 K/W | Lower thermal efficiency requires larger copper area for same power dissipation | Prefer when sourcing from Nexperia's high-volume SOT-89 supply chain |
| MMBT5087LT1G (ON Semiconductor) | Lower VCEO (50 V), hFE 125–250, SOT-23 package (lower Ptot = 350 mW) | Not suitable for >500 mA or >50 V applications; limited thermal capability | Select only for low-power signal switching where footprint reduction outweighs power handling |
Compared with BCX52-16E6327, the Nexperia variant trades 3 K/W higher thermal resistance for broader distribution, while the ON Semiconductor part sacrifices voltage rating and power capacity for miniaturization - making BCX52-16E6327 optimal for medium-power automotive and industrial switching where reliability and thermal headroom are critical.

FAQ
Is BCX52-16E6327 pin-compatible with BCX52-16,115?
Yes - both use identical SOT-89 package with Base (Pin 1), Collector (Pin 2), Emitter (Pin 3) pinout and share identical mechanical footprint and solder pad dimensions per Infineon EHP00437 and Nexperia SOT89 standards.
What is the maximum allowable base current for continuous operation?
The absolute maximum DC base current is 100 mA per datasheet Section 2. Exceeding this risks metallization failure; for 500 mA collector drive, 50 mA base current is recommended to maintain VCE(sat) ≤ 0.5 V without thermal runaway.
Does BCX52-16E6327 support pulsed operation beyond 1 A?
Yes - peak collector current ICM is 1.5 A for pulse widths ≤ 10 ms (duty cycle ≤ 2%), validated per Figure 6 (Permissible Pulse Load) in the datasheet, provided TJ remains ≤ 150 °C.
Can BCX52-16E6327 replace BCX53-16 in a 80 V circuit?
No - BCX52-16E6327 has VCEO = 60 V and VCBO = 60 V; using it in an 80 V circuit exceeds absolute maximum ratings and risks catastrophic breakdown. BCX53-16 (VCEO = 80 V) is required for that voltage class.
