Product details
Overview
PBHV8515QAZ from Nexperia is an NPN high-voltage low-VCEsat BISS transistor in a DFN1010D-3 (SOT1215) package, rated for 150 V VCEO, 500 mA IC, and 200 mV typical VCEsat at IC = 100 mA / IB = 20 mA. It delivers high hFE (100–215 at 100 mA), AEC-Q101 qualification, and 0.37 mm profile-designed for space-constrained automotive LED drivers and HID front lighting.
For engineers reviewing the PBHV8515QAZ datasheet, PBHV8515QAZ pinout, PBHV8515QAZ application, or PBHV8515QAZ equivalent, this page provides verified technical context, validated pin functions, real-world use cases in automotive power switching, and confirmed alternatives with documented parameter-level differences.
Technical Context
This BISS transistor uses a breakthrough small-signal structure optimized for high-voltage switching with minimal saturation loss. Its architecture enables stable hFE > 100 up to 200 mA and supports pulsed IC peaks of 1 A under defined thermal conditions.
Designed for automotive-grade reliability, it operates across −55 °C to +150 °C ambient, features low thermal resistance (125 K/W on 4-layer PCB with 1 cm² collector pad), and integrates side-wettable flanks for AOI-compatible solder joint inspection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 150 V - Enables direct interface with 120 V DC bus or boost-stage outputs in automotive SMPS and HID ballasts. |
| IC | 500 mA continuous - Sustains steady-state current for multi-LED string drivers without derating at Tamb ≤ 75 °C. |
| VCEsat | 200 mV typ. @ IC=100 mA/IB=20 mA - Reduces conduction loss to <10 mW, critical for thermally constrained modules. |
| hFE | 100–215 @ VCE=10 V, IC=100 mA - Ensures robust base drive margin and stable gain across temperature (−55 to +100 °C). |
| fT | 75 MHz @ VCE=10 V, IC=10 mA - Supports fast switching in PWM-controlled LED dimming and motor gate drive circuits. |
| Rth(j-a) | 125 K/W @ 4-layer PCB, 1 cm² collector pad - Allows 1 W dissipation at ΔT = 125 K, enabling compact thermal design. |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive discrete semiconductors, including HTGB, HTRB, and ESD. |
Pinout & Package
DFN1010D-3 (SOT1215) is a leadless, ultra-thin (0.37 mm height), thermal-enhanced plastic package with visible and solderable side pads for automated optical inspection. Dimensions: 1.1 × 1.0 × 0.37 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control input requiring ~20 mA drive for full saturation at 100 mA load; low VBEsat (0.95–1.2 V) minimizes driver loss. |
| 2 | Emitter (E) | Reference node tied to ground or low-side return path; electrically isolated from package thermal pad (no internal connection). |
| 3 & 4 | Collector (C) | Dual-terminal collector layout improves current sharing and thermal spreading; both pins must be connected to high-voltage rail or heatsink area. |
Key Features
| Feature | Design Value |
|---|---|
| High voltage rating | 150 V VCEO enables direct replacement of older 100 V transistors in upgraded 48 V/60 V automotive systems. |
| Low VCEsat | 200 mV typ. reduces power loss by >40% vs. standard BJT equivalents at same IC, lowering thermal load in sealed modules. |
| AEC-Q101 qualification | Validated for automotive underhood environments, including temperature cycling, humidity bias, and mechanical shock testing. |
| Side-wettable flanks | Enables 100% AOI coverage of solder joints without X-ray, reducing post-reflow inspection cost and defect escape risk. |
| Ultra-low profile | 0.37 mm height allows integration into sub-1 mm board stacks used in headlamp control modules and sensor fusion PCBs. |
Applications
| LED Chain Driver | HID Front Lighting |
|---|---|
Use Scenario: Driving 3–5 series-connected LEDs from a 12–24 V supply in automotive interior lighting modules. IC Role / Device Role / Timing Role: Low-side switch controlling LED current via PWM at 1–10 kHz; handles repetitive 500 mA pulses. Use Value: 200 mV VCEsat limits heat generation to <100 mW, eliminating need for thermal vias or copper pours in thin-flex PCBs. |
Use Scenario: Ignition pulse generation and AC sustain control in automotive HID headlamp ballasts. IC Role / Device Role / Timing Role: High-voltage switch triggering igniter transformers and regulating lamp current during warm-up phase. Use Value: 150 V VCEO withstands transient spikes >100 V during arc ignition, while AEC-Q101 ensures lifetime reliability in vibration-prone mounting locations. |
| Automotive Motor Management | SMPS Primary-Side Switch |
Use Scenario: Controlling small BLDC fan motors or solenoid valves in engine bay ECUs. IC Role / Device Role / Timing Role: Low-side driver in half-bridge configurations; switches at ≤20 kHz with 820 ns turn-off time. Use Value: 75 MHz fT and 170 ns fall time support clean edge integrity, minimizing shoot-through risk and EMI in noisy underhood environments. |
Use Scenario: Discrete switch in flyback or forward converter primary stages operating at 65–130 kHz. IC Role / Device Role / Timing Role: Main power switch handling 500 mA DC + 1 A peak current during startup and overload events. Use Value: 1 A ICM and 1 W Ptot (4-layer PCB) allow safe operation without active cooling in compact AC/DC adapters and infotainment power supplies. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage low-VCEsat transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PBH8515QAZ | Same package and pinout; lower VCEO (100 V) and higher VCEsat (300 mV typ.) | Restricted to 48 V systems; unsuitable for HID or 120 V boost stages | Select only when voltage stress <80 V and thermal budget permits +50% conduction loss. |
| BCX56-16 | TO-92 package; 80 V VCEO, 1 A IC, 500 mV VCEsat; no AEC-Q101 or AOI support | Requires manual assembly; limited to non-automotive, non-space-constrained designs | Use only for prototyping or legacy through-hole boards where rework tolerance outweighs size/performance needs. |
Compared with PBHV8515QAZ, PBH8515QAZ trades voltage headroom for identical footprint compatibility, while BCX56-16 sacrifices automotive qualification and miniaturization for higher current and legacy manufacturability-neither matches the combined 150 V / 200 mV / AEC-Q101 specification set.

FAQ
What is the maximum allowable junction temperature for PBHV8515QAZ?
The absolute maximum junction temperature (Tj) is 150 °C per the datasheet Limiting Values table. Operation above this threshold risks permanent degradation of hFE and increased leakage. Derating is required above 25 °C ambient-e.g., Ptot drops to 0.54 W at 100 °C ambient on a 4-layer PCB with 1 cm² collector pad.
Is PBHV8515QAZ pin-compatible with its PNP complement PBHV9515QA?
No-PBHV9515QA uses the same DFN1010D-3 package but has reversed pinning: Pin 1 = Emitter, Pin 2 = Base, Pin 3 & 4 = Collector. Direct substitution would reverse polarity and cause circuit failure; layout must be mirrored or dedicated footprints used.
Does PBHV8515QAZ require a base resistor in all applications?
Yes-a current-limiting base resistor is mandatory to prevent excessive IB. For 100 mA IC with hFE ≥ 100, minimum IB = 1 mA; using 3.3 V logic drive, RB ≈ 3.3 kΩ ensures safe saturation while limiting IB to <200 mA peak per Absolute Maximum Ratings.
Can PBHV8515QAZ be used in linear regulator applications?
No-it is optimized for switching operation, not linear regulation. Its low VCEsat and high hFE do not compensate for poor Safe Operating Area (SOA) in linear mode; power dissipation would exceed Ptot limits rapidly under VCE > 5 V and IC > 200 mA.
