Product details
Overview
BC807W-Q from Nexperia is a PNP general-purpose bipolar junction transistor (BJT) in SOT323 (SC-70) package, rated for −45 V VCEO, −500 mA IC, and DC current gain (hFE) of 100–600 at VCE = −1 V and IC = −100 mA. It serves as a compact, AEC-Q101-qualified switching and amplification device in automotive body control modules, LED drivers, and power management circuits.
For engineers reviewing the BC807W-Q datasheet, BC807W-Q pinout, BC807W-Q application, or BC807W-Q equivalent, this page delivers verified electrical parameters, thermal derating behavior, pin-functional mapping, automotive qualification status, and direct alternatives with documented hFE and saturation voltage differences.
Technical Context
This PNP BJT operates in active, saturation, and cutoff regions with base-controlled current amplification. Its hFE range (100–600) supports both low-gain switching (e.g., digital logic interface) and medium-gain analog amplification (e.g., sensor signal conditioning), while its −700 mV VCE(sat) at IC = −500 mA / IB = −50 mA enables efficient low-voltage switching in 3.3 V and 5 V systems.
Thermal resistance Rth(j-a) is 625 K/W on standard FR4 PCB and improves to 431 K/W with 1 cm² collector pad - enabling sustained operation up to 150 °C junction temperature under defined mounting conditions and pulse duty cycles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −45 V: Maximum safe collector-emitter voltage with open base; defines maximum supply rail compatibility in high-side switch configurations. |
| IC | −500 mA continuous: Rated collector current at 25 °C ambient; sets upper limit for load-driving capability in relay drivers or fan controllers. |
| hFE | 100–600 at VCE = −1 V, IC = −100 mA: Wide DC current gain range allows flexible base drive design across varying load impedances and temperature conditions. |
| VCE(sat) | −700 mV max at IC = −500 mA, IB = −50 mA: Low saturation voltage minimizes conduction loss and self-heating in high-duty-cycle switching applications. |
| Ptot | 200 mW at Tamb ≤ 25 °C (standard footprint): Power dissipation limit determines thermal margin in sealed enclosures or stacked PCBs without forced airflow. |
| Tj(max) | 150 °C: Maximum junction temperature; requires thermal design adherence to derating curves (e.g., ≤125 °C ambient for full-rated current). |
Pinout & Package
SOT323 (SC-70) plastic surface-mounted package: ultra-compact 3-lead outline measuring 2.2 mm × 1.35 mm × 0.95 mm (L × W × H), optimized for high-density automotive PCB layouts and reflow soldering per IPC-7095.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Current-controlled input node; requires series resistor to limit IB and ensure reliable saturation or cutoff based on driving logic level. |
| 2 | Emitter (E) | Common reference terminal for PNP configuration; connected to higher potential (e.g., VCC) in high-side switch topologies. |
| 3 | Collector (C) | Output current path; sinks load current to ground or lower-potential node when transistor is biased ON. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and ESD robustness - suitable for under-hood and cabin electronics. |
| Three hFE variants | BC807W-Q (100–600), BC807-16W-Q (100–250), BC807-25W-Q (160–400), BC807-40W-Q (250–600) - enables precise gain matching without redesigning base drive networks. |
| Low VCE(sat) | −700 mV max at IC = −500 mA ensures <1.5% voltage drop across transistor in 48 V automotive loads, reducing heat sink requirements. |
| High VCB0 | −50 V collector-base breakdown supports operation in noisy 24 V/48 V systems with transient spikes up to ±40 V without avalanche conduction. |
Applications
| Automotive Door Module | Industrial PLC Output Stage |
|---|---|
|
Use Scenario: Driving window lift motor relays and interior lighting PWM dimming circuits in door control units. IC Role / Device Role / Timing Role: PNP high-side switch controlling 12 V loads via microcontroller GPIO with inverted logic. Use Value: −45 V VCEO withstands load-dump transients; −700 mV VCE(sat) limits power loss to <350 mW at 500 mA, eliminating need for heatsinking. |

IC Role / Device Role / Timing Role: General-purpose discrete switch interfacing TTL/CMOS logic to industrial 24 V field devices. Use Value: AEC-Q101 qualification ensures long-term reliability in factory environments; 150 °C Tj(max) supports operation near hot control cabinets. |
| USB-C Power Path Control | Medical Sensor Signal Conditioning |
|

IC Role / Device Role / Timing Role: Low-loss PNP pass element in reverse-polarity protected power routing circuit. Use Value: 200 mW Ptot and 625 K/W Rth(j-a) allow stable 500 mA operation at 50 °C ambient without thermal throttling. |
Use Scenario: Amplifying low-level thermistor or strain gauge outputs in portable diagnostic equipment. IC Role / Device Role / Timing Role: Medium-gain linear amplifier stage with predictable hFE stability over −40 °C to +85 °C. Use Value: hFE variation ≤±15% across temperature ensures consistent gain calibration; low Cc (5 pF) preserves bandwidth in sub-MHz sensor interfaces. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP general-purpose transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC807-16W-Q | hFE = 100–250 (narrower range); otherwise identical VCEO, IC, VCE(sat), and package. | Better suited for digital switching where tight gain tolerance reduces base drive variability. | Select when deterministic turn-on/off thresholds are required and gain spread must be minimized. |
| BC857BW-Q | Same SOT323 package but NPN complement; VCEO = 45 V, IC = 100 mA, hFE = 200–450 - not functionally interchangeable without circuit topology change. | Used in low-current NPN configurations (e.g., level shifting, small-signal amplification), not direct replacement. | Choose only for NPN-based designs requiring matched automotive qualification and footprint. |
Compared with BC807-16W-Q, BC807W-Q offers broader hFE flexibility for analog gain tuning; versus BC857BW-Q, it provides higher current handling and PNP polarity essential for high-side switching - making BC807W-Q uniquely suitable for automotive load control where polarity and 500 mA capability are mandatory.

FAQ
What is the maximum allowable base current for continuous operation?
The absolute maximum peak base current is −200 mA per limiting values table, but continuous operation must respect power dissipation limits. At 25 °C ambient, with typical VBE ≈ −1.2 V, sustained IB > −167 mA would exceed 200 mW Ptot. Design practice limits IB to ≤ −50 mA for reliable 500 mA IC switching with adequate gain margin.
Does BC807W-Q support pulsed operation beyond its DC ratings?
Yes - it supports ICM = −1 A for single pulses ≤1 ms, provided duty cycle remains ≤2% (tp ≤ 300 μs, δ ≤ 0.02). Transient thermal impedance data (Fig. 2–3) confirms safe operation under these conditions on standard FR4 PCB, enabling short-circuit protection and surge handling.
How does thermal performance differ between standard and enhanced PCB mounting?
Rth(j-a) drops from 625 K/W (standard footprint) to 431 K/W with a 1 cm² copper pad on the collector lead. This 31% improvement allows 30% higher continuous current at 70 °C ambient before reaching 150 °C Tj, directly enabling higher-power operation without board redesign.
Is marking code '5D%' unique to BC807W-Q across Nexperia's portfolio?
Yes - per Table 5, '5D%' is the exclusive marking code for BC807W-Q, where '%' denotes the manufacturing site identifier. BC807-16W-Q uses '5A%', BC807-25W-Q '5B%', and BC807-40W-Q '5C%', enabling unambiguous visual identification on assembled PCBs.
