Product details
Overview
BCX5210TA from Diodes Incorporated is a PNP medium-power bipolar junction transistor in SOT89 package, rated for -60V VCEO, -1A continuous collector current, and < -500mV VCE(sat) at -0.5A. It serves as a switching or linear amplification device in automotive and industrial power stages, with validated thermal resistance of 83°C/W (on 25mm × 25mm 1oz copper).
For engineers reviewing the BCX5210TA datasheet, BCX5210TA pinout, BCX5210TA application, or BCX5210TA equivalent, key selection criteria include its complementary NPN pairing (BCX55), low saturation voltage under medium-load conditions, AEC-Q101 readiness for automotive use, and SOT89 thermal performance on standard PCB copper areas.
Technical Context
The BCX5210TA operates as a silicon PNP BJT with fixed gain structure optimized for medium-current switching. Its DC current gain (hFE) ranges from 40 to 250 depending on collector current (5mA–500mA) and VCE = -2V, supporting both saturated-switching and active-region amplification modes.
Thermal design relies on the exposed collector pad: RθJL = 13°C/W confirms direct thermal path to PCB copper, while RθJA varies from 125°C/W (15mm²) to 60°C/W (50mm²), enabling scalable power handling up to 2W with adequate layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -60 V - Maximum safe collector-emitter reverse bias before breakdown in common-emitter configuration. |
| IC (cont.) | -1 A - Continuous collector current rating defining steady-state switching or amplification capability. |
| VCE(sat) | < -500 mV @ -0.5A - Ensures minimal conduction loss and heat generation when fully turned on. |
| hFE | 40–250 - Gain range supports stable biasing across temperature (-55°C to +150°C) and load variation. |
| fT | 150 MHz - Enables use in audio-frequency switching and low-MHz signal amplification without bandwidth limitation. |
| RθJA | 83 °C/W - Thermal resistance on 25mm × 25mm 1oz copper, directly informing heatsinking requirements. |
| PD | 1.5 W - Maximum dissipation under specified mounting condition, limiting duty-cycle or ambient temperature operation. |
Pinout & Package
Package: SOT89 - Surface-mount plastic package with exposed collector pad for enhanced thermal conduction and mechanical stability. Molded in halogen- and antimony-free "Green" compound (UL 94V-0), moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | E | Current exit terminal; connected to higher potential in PNP operation; requires low-impedance return path for stable biasing. |
| 2 (Base) | B | Control input; drives transistor into saturation or cutoff; requires current-limited drive due to hFE-dependent base current demand. |
| 3 (Collector) | C | Main power terminal; electrically and thermally tied to exposed metal pad; must be soldered to ≥25mm² copper for rated 1.5W dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Complementary NPN pairing | BCX55TA provides matched VCEO, IC, and thermal specs for push-pull or H-bridge designs. |
| AEC-Q101 readiness | Manufactured in IATF 16949-certified facilities; PPAP-capable for automotive-grade supply chain traceability. |
| Low VCE(sat) | < -500 mV at -0.5A enables >95% efficiency in 12V/24V medium-power switches (e.g., solenoid drivers). |
| Green packaging | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) meets global environmental compliance mandates. |
| ESD robustness | 4 kV HBM and 1 kV CDM ratings reduce risk of assembly-line damage and field failure in unshielded environments. |
Applications

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 = -60V, IC = -1A, but SOT223 package; RθJA = 100°C/W (higher thermal resistance). | Larger footprint and lower thermal performance limit use in space-constrained 1.5W applications. | Select if board layout accommodates SOT223 and thermal margin allows 100°C/W derating. |
| MJD2955T4G | VCEO = -60V, IC = -10A, TO-220 package; significantly higher power but larger size and cost. | Over-specified for ≤1.5W loads; requires heatsink even at moderate duty cycles. | Choose only when future-proofing for >5A peak loads or legacy TO-220 compatibility is required. |
Compared with ZTX753 and MJD2955T4G, BCX5210TA delivers optimal balance of SOT89 compactness, 83°C/W thermal performance on standard PCBs, and automotive-ready manufacturing-making it preferred for cost-sensitive, thermally constrained medium-power switching where footprint and qualification matter.

FAQ
What is the maximum continuous collector current for BCX5210TA?
The BCX5210TA is rated for -1A continuous collector current (IC) at TA = +25°C with proper PCB copper area (25mm × 25mm 1oz). Derating applies above +25°C per the datasheet's thermal curve; at +100°C ambient, max IC drops to approximately -0.6A to maintain junction temperature below 150°C.
Is BCX5210TA qualified for automotive applications?
Yes-BCX5210TA is manufactured in IATF 16949-certified facilities and supports PPAP documentation. While not pre-qualified to AEC-Q101 out-of-box, Diodes states it meets requirements for automotive applications "requiring specific change control," and full qualification can be initiated upon customer request with test plan alignment.
How does the SOT89 package improve thermal performance over SOT23?
The SOT89 package features an exposed collector pad that provides direct thermal conduction to PCB copper, achieving RθJA = 83°C/W on 25mm² copper-nearly 2× better than typical SOT23 RθJA (~150–200°C/W). This enables 1.5W dissipation without a heatsink, whereas SOT23 would require forced air or derating below 0.5W.
Can BCX5210TA be used in linear amplification mode?
Yes-its hFE of 40–250 across IC = 5mA–500mA and VCE = -2V, combined with fT = 150MHz, supports stable small-signal and medium-power linear amplification. Designers must ensure VCE remains > -2V and power dissipation stays within derated limits to avoid thermal runaway.
