Product details
Overview
BCV28 from Nexperia is a PNP Darlington transistor in SOT89 package, delivering minimum DC current gain of 4000 at −1 mA collector current and up to 20,000 at −100 mA, with −30 V VCE rating and −500 mA continuous collector current - used for high-gain switching and amplification in automotive sensor interface circuits.
For engineers reviewing the BCV28 datasheet, BCV28 pinout, BCV28 application, or BCV28 equivalent, key selection criteria include verified AEC-Q101 qualification, thermal resistance (Rth(j-sp) = 16 K/W), saturation voltage (VCEsat ≤ −1 V), and complementary NPN pairing with BCV29 in space-constrained SMT designs.
Technical Context
The BCV28 integrates two cascaded PNP transistors in a monolithic Darlington configuration, enabling ultra-high hFE without external bias networks. Its structure supports low-base-drive operation while maintaining robust thermal performance on FR4 PCBs with 6 cm² collector pad.
It operates under AEC-Q101 stress testing for automotive environments, with absolute maximum ratings including −40 V VCBO, −10 V VEBO, and 150 °C junction temperature - validated for use in engine control modules and body electronics where reliability under thermal cycling is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCE max | −30 V - defines maximum allowable collector-emitter voltage before breakdown in switching applications |
| hFE min @ IC = −1 mA | 4000 - ensures stable base-current-limited operation in low-signal amplification stages |
| IC continuous | −500 mA - supports direct driving of medium-power loads such as relays or LED arrays |
| VCEsat max | −1 V - minimizes conduction loss and self-heating during saturated switching |
| Rth(j-sp) | 16 K/W - enables predictable thermal management using standard SOT89 solder-point layout |
| AEC-Q101 qualified | Yes - certified for automotive-grade reliability per discrete semiconductor stress test standard |
Pinout & Package
SOT89 (SC-62) flat-lead surface-mount plastic package: 4.5 mm × 2.5 mm × 1.5 mm body, 1.5 mm lead pitch, collector-connected tab for thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter | Current exit path; connected to ground or negative rail in common-emitter configurations |
| 2 | Collector | Main output terminal; electrically and thermally tied to exposed tab for heat transfer to PCB |
| 3 | Base | Control input; requires minimal drive current due to Darlington gain architecture |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-high DC current gain | hFE ≥ 20,000 at −100 mA enables single-stage amplification without additional gain stages |
| Automotive qualification | AEC-Q101 compliance confirms suitability for under-hood and chassis-mounted electronic control units |
| Low saturation voltage | VCEsat ≤ −1 V reduces power loss and improves efficiency in high-duty-cycle switching |
| Thermally optimized package | SOT89 collector tab delivers Rth(j-sp) = 16 K/W - simplifies thermal design on standard FR4 boards |
Applications
| Engine Coolant Temperature Sensor Interface | Automotive Door Lock Actuator Driver |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP Darlington transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCV27 | Lower hFE (min 2000 vs. 4000), same SOT89 package and −30 V rating | Less suitable for ultra-low-base-drive designs; requires higher base current for same collector load | Select when cost sensitivity outweighs gain requirement and thermal margin is ample |
| ZTX951 | TO-92 package, higher VCE (−60 V), hFE min 1000 at −150 mA | Not SMT-compatible; larger footprint and inferior thermal resistance (Rth(j-a) ≈ 200 K/W) | Choose only if through-hole assembly is mandated and voltage headroom >−40 V is required |
Compared with BCV27 and ZTX951, the BCV28 uniquely balances ultra-high gain, AEC-Q101 qualification, and SOT89 thermal performance - making it optimal for space-constrained, high-reliability automotive switching where base drive efficiency and thermal predictability are critical.

FAQ
What is the maximum continuous collector current for BCV28?
The BCV28 supports −500 mA continuous collector current at Tamb ≤ 25 °C with proper PCB thermal design (6 cm² copper pad). At elevated ambient temperatures or reduced copper area, derating applies per the thermal resistance curve in section 9 of the datasheet - e.g., at 85 °C ambient, maximum usable IC drops to approximately −320 mA.
Is BCV28 pin-compatible with BCV29?
No - BCV28 (PNP) and BCV29 (NPN) share identical SOT89 package and pinout (Emitter–Collector–Base), but their polarity and biasing requirements differ fundamentally. Swapping them without circuit redesign will result in non-functional or damaged operation; they are functional complements, not drop-in replacements.
Does BCV28 require a heatsink in typical automotive applications?
Not typically - its Rth(j-sp) of 16 K/W allows safe operation up to ~1.1 W dissipation with standard FR4 mounting. At full −500 mA and −1 V VCEsat, power dissipation is 0.5 W, resulting in ~8 °C junction-to-solder-point rise - well within the 150 °C Tj limit even at 105 °C ambient.
What marking code identifies BCV28 on the device body?
The BCV28 is marked with "ED" on the top surface of the SOT89 package, as confirmed in Table 4 of the official Nexperia datasheet. This two-character code is laser-etched or molded and appears adjacent to the device outline; no date codes or lot identifiers are part of the standard marking.
