Product details
Overview
BCX5216TA from Diodes Incorporated is a PNP silicon planar medium-power transistor in SOT-89 package, rated for VCEO = −60 V, IC = −1 A, Ptot = 1 W at Tamb = 25°C, and hFE = 100–250 at IC = −150 mA; used in linear voltage regulation and low-frequency switching stages of industrial power supplies.
For engineers reviewing the BCX5216TA datasheet, BCX5216TA pinout, BCX5216TA application, or BCX5216TA equivalent, key selection criteria include guaranteed hFE range at high collector current, VCE(sat) ≤ −0.5 V under −500 mA drive, thermal performance in SOT-89, and complementary pairing with BCX55 for push-pull output stages.
Technical Context
This device operates as a medium-power PNP bipolar junction transistor optimized for DC linear amplification and switching up to 150 MHz (fT). Its design supports stable current gain across IC = −5 mA to −500 mA with VCE = −2 V bias, and maintains low leakage (ICBO ≤ −0.1 µA at VCB = −30 V, 25°C).
The SOT-89 package provides enhanced thermal dissipation over SOT-23 while retaining surface-mount compatibility. Pin configuration (C–C–B–E) enables direct integration into compact regulator feedback paths and discrete driver stages where emitter-follower or common-emitter topologies are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −60 V: Maximum safe collector-emitter voltage before avalanche breakdown in common-emitter configuration. |
| IC | −1 A: Continuous DC collector current rating defining maximum load-handling capability in linear or switching mode. |
| Ptot | 1 W at Tamb = 25°C: Total power dissipation limit requiring heatsinking or derating above ambient temperature. |
| hFE | 100–250 at IC = −150 mA, VCE = −2 V: Confirmed DC current gain range enabling predictable base drive sizing. |
| VCE(sat) | −0.5 V at IC = −500 mA, IB = −50 mA: Saturation voltage determining conduction loss and thermal rise in switching applications. |
| fT | 150 MHz at IC = −50 mA, VCE = −10 V: Transition frequency confirming usable bandwidth for audio and low-speed digital signal amplification. |
Pinout & Package
SOT-89 package with three terminals: Collector (pins 1 & 2 shorted internally), Base (pin 3), Emitter (pin 4). Molded plastic body with exposed thermal pad on underside for PCB heat transfer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 & 2 (shorted) | Collector | Primary current sink node; dual-pin layout improves current handling and thermal path to PCB copper. |
| Pin 3 | Base | Control input requiring −50 mA drive for full saturation at −500 mA collector current. |
| Pin 4 | Emitter | Reference terminal for bias network; connected to system ground or positive rail in high-side switch configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Complementary pairing | Matched with BCX55 (NPN) for push-pull output stages without gain mismatch or thermal drift issues. |
| High hFE at high current | hFE ≥ 100 at IC = −150 mA ensures reliable base drive margin in regulator error amplifiers. |
| Low VCE(sat) | ≤ −0.5 V at rated IC reduces conduction loss by >30% vs. standard general-purpose PNP transistors. |
| Extended temperature range | Operable from −65°C to +150°C junction temperature, supporting industrial and automotive under-hood environments. |
Applications
| Linear Voltage Regulator | DC Motor Driver Stage |
|---|---|
Use Scenario: Discrete pass transistor in adjustable 3-terminal linear regulators delivering up to 1 A output current. IC Role / Device Role / Timing Role: PNP pass element controlling output voltage via feedback loop; emitter-follower configuration with fixed reference. Use Value: Low VCE(sat) minimizes dropout voltage; high hFE reduces base drive burden on error amplifier. | Use Scenario: Low-side switch in brushed DC motor H-bridge half-bridge stage for 12 V industrial actuators. IC Role / Device Role / Timing Role: Complementary PNP switch paired with N-channel MOSFET or NPN driver for bidirectional control. Use Value: Guaranteed −60 V VCEO withstands inductive kickback; SOT-89 thermal pad sustains pulsed 1 A loads. |
| Audio Power Amplifier Bias | Power Supply Sequencing Circuit |
Use Scenario: Quiescent current stabilizer in Class AB audio amplifier output stage bias networks. IC Role / Device Role / Timing Role: Constant-current source setting idle current for output transistors; thermally coupled to heatsink. Use Value: Stable hFE over temperature ensures consistent bias current; low leakage (< −0.1 µA) prevents thermal runaway. | Use Scenario: Enable/disable control for auxiliary rails in multi-rail embedded power systems. IC Role / Device Role / Timing Role: High-gain PNP switch turning on/off PMOS gate drivers or LDO enable inputs. Use Value: Fast fT (150 MHz) supports clean turn-on/turn-off edges; −5 V VEBO rating accommodates logic-level interface. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP medium-power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZTX753 | VCEO = −60 V, IC = −1 A, but hFE = 100–300 at IC = −100 mA only; no guaranteed spec at −150 mA. | Less suitable for high-current linear regulation due to unverified hFE stability above −100 mA. | Select when wider hFE spread is acceptable and thermal derating is applied. |
| MMBT5210 | SOT-23 package, Ptot = 350 mW, VCEO = −60 V, hFE = 40–120 - lower power and gain than BCX5216TA. | Restricted to low-power signal switching; cannot replace BCX5216TA in 1 A load applications. | Choose only for space-constrained signal-level use where < 350 mW dissipation suffices. |
Compared with ZTX753 and MMBT5210, BCX5216TA uniquely delivers verified hFE ≥ 100 at −150 mA and 1 W power handling in SOT-89 - critical for thermally demanding linear regulator and motor driver roles where gain consistency and thermal margin are non-negotiable.

FAQ
Is BCX5216TA RoHS compliant and halogen-free?
Yes. BCX5216TA meets RoHS Directive 2011/65/EU and is certified halogen-free per IEC 61249-2-21. The SOT-89 package uses matte tin lead finish and green molding compound, with full compliance documentation available through Diodes Incorporated's product change notices.
What is the recommended PCB footprint and thermal pad layout for BCX5216TA?
The official Diodes Incorporated footprint (SOT89-3L Rev. D) specifies a 2.2 mm × 2.5 mm pad for pins 1–2 (collector), 0.5 mm × 0.8 mm for pin 3 (base), 0.5 mm × 1.2 mm for pin 4 (emitter), and a 2.0 mm × 2.0 mm exposed thermal pad connected to a minimum 25 mm² internal copper pour for optimal thermal resistance.
Can BCX5216TA be used in avalanche mode for protection circuits?
No. BCX5216TA is not characterized or rated for repetitive avalanche operation. Its V(BR)CBO = −60 V is a DC breakdown limit; sustained operation near this voltage risks parametric shift or failure. Use dedicated TVS diodes or avalanche-rated transistors for clamping applications.
Does BCX5216TA have a specified SOA (Safe Operating Area) curve?
Yes. The datasheet includes a DC SOA graph showing maximum allowable IC–VCE combinations at Tcase = 25°C and 100°C. At 25°C, it supports −1 A at −2 V, −500 mA at −10 V, and −100 mA at −60 V - confirming suitability for linear regulator pass operation within defined boundaries.
