Product details
Overview
BC807-25W from Nexperia is a PNP bipolar junction transistor (BJT) in SOT323 (SC-70) package, rated for −45 V VCEO, −500 mA IC, and DC current gain (hFE) of 160–400 at VCE = −1 V and IC = −100 mA. It serves as a general-purpose switching and amplification device in low-power analog and digital interface circuits.
For engineers reviewing the BC807-25W datasheet, BC807-25W pinout, BC807-25W application, or BC807-25W equivalent, this page delivers verified electrical parameters, thermal derating behavior, base-emitter saturation voltage (VBE(sat) ≤ −1.2 V), collector-emitter saturation voltage (VCE(sat) ≤ −700 mV), and SOT323 footprint compatibility for high-density PCB layouts.
Technical Context
This PNP transistor operates with open-base collector-emitter breakdown voltage of −45 V and emitter-base breakdown voltage of −5 V, supporting robust biasing in negative-rail signal conditioning and level-shifting topologies. Its pulsed DC current gain range (160–400) enables stable small-signal amplification and reliable switching across industrial temperature ranges (−65 °C to 150 °C).
Thermal resistance from junction to ambient is 431 K/W on FR4 PCB with 1 cm² collector pad, and 625 K/W under standard footprint conditions - critical for thermal design in space-constrained consumer and IoT applications. Power dissipation is limited to 290 mW under optimized mounting and derates linearly above 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −45 V: Maximum safe collector-emitter voltage with base open; defines rail-to-rail headroom in PNP switch configurations. |
| IC | −500 mA continuous: Sustained collector current capability; supports medium-current load switching (e.g., LED drivers, relay coils). |
| hFE | 160–400 at VCE = −1 V, IC = −100 mA: Predictable current amplification for stable bias network design in amplifier stages. |
| VCE(sat) | ≤ −700 mV at IC = −500 mA, IB = −50 mA: Low saturation voltage minimizes power loss and heating in saturated-switch operation. |
| VBE(sat) | ≤ −1.2 V at IC = −500 mA: Confirmed base drive requirement for full turn-on; informs logic-level compatibility with microcontroller GPIOs. |
| fT | 80 MHz at VCE = −5 V, IC = −10 mA: Transition frequency enabling audio-frequency amplification and fast digital switching up to ~10 MHz. |
| Ptot | 290 mW on FR4 with 1 cm² collector pad: Absolute maximum power handling under defined PCB layout; derates linearly above 25 °C ambient. |
Pinout & Package
SOT323 (SC-70) plastic surface-mounted package: ultra-compact 3-lead footprint (2.2 mm × 1.35 mm × 0.95 mm), optimized for high-density routing and reflow-compatible assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control terminal; requires ≥−1.2 V and sufficient base current (e.g., −13 mA typical for 500 mA collector drive) to saturate the transistor. |
| 2 | Emitter (E) | Current source terminal; connected to higher potential rail (e.g., VCC) in common-emitter switch configurations. |
| 3 | Collector (C) | Current sink terminal; routes load current to ground or lower-potential node; thermally coupled to PCB pad per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Three hFE variants | BC807-16W (100–250), BC807-25W (160–400), BC807-40W (250–600): Enables precise gain matching for production consistency in analog gain blocks. |
| Low VCE(sat) | ≤ −700 mV at IC = −500 mA ensures <150 mW conduction loss in switching mode - critical for battery-powered efficiency. |
| High fT | 80 MHz transition frequency supports stable operation in audio preamps and clock buffer stages up to 10 MHz fundamental. |
| Robust thermal rating | 150 °C max junction temperature and defined derating curves allow operation in sealed enclosures without forced airflow. |
| Standard SC-70 footprint | Compatible with JEDEC-standard reflow profiles and wave soldering footprints (Fig. 17/18); eliminates custom stencil requirements. |
Applications
| LED Driver Circuit | Microcontroller Level Shifter |
|---|---|
Use Scenario: Driving multiple 20 mA indicator LEDs from a 3.3 V MCU GPIO in active-low configuration. IC Role / Device Role / Timing Role: PNP switch sinking current from VCC through LED to MCU pin (logic-low turn-on). Use Value: VCE(sat) ≤ −700 mV ensures >2.6 V forward voltage margin for red/green LEDs while limiting junction temperature rise to <15 °C at 500 mA peak. |
Use Scenario: Translating 5 V logic signals down to 3.3 V for interfacing legacy peripherals with modern microcontrollers. IC Role / Device Role / Timing Role: Active-low level shifter using emitter-follower configuration with base biased to 3.3 V. Use Value: hFE ≥ 160 guarantees minimal base current loading (<30 µA) on the 3.3 V rail while maintaining <10 ns propagation delay due to 80 MHz fT. |
| Power Supply Enable Switch | Audio Signal Inverter |
Use Scenario: Enabling/disabling a 12 V auxiliary rail via microcontroller command in an industrial sensor node. IC Role / Device Role / Timing Role: High-side PNP switch controlling PMOS gate drive or directly sourcing load current. Use Value: −45 V VCEO provides 3× safety margin over 12 V rail; −500 mA IC supports up to 100 mA load with 5× derating for reliability. |
Use Scenario: Inverting low-level audio signals (≤100 mVpp) in portable headphone amplifier feedback paths. IC Role / Device Role / Timing Role: Common-emitter amplifier stage with fixed-gain bias network (RC/RB). Use Value: 160–400 hFE range allows predictable gain setting (AV ≈ −hFERC/RE) with <±5% variation across production lots. |
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 |
|---|---|---|---|
| BC807-25 | Same electrical specs but in larger SOT23 package (3.0 mm × 1.4 mm); 290 mW Ptot at 25 °C vs. 200 mW for BC807-25W. | Less suitable for ultra-dense layouts; better thermal performance in non-optimized PCBs. | Select when board space permits and thermal margin is prioritized over miniaturization. |
| MMBT3906LT1G | hFE = 100–300 (lower max gain); VCEO = −40 V; same SOT23 footprint but not SOT323-compatible. | Requires PCB redesign; lower VCEO limits use in 36 V systems. | Choose only if existing SOT23 footprint reuse is mandatory and −40 V rating suffices. |
Compared with BC807-25 and MMBT3906LT1G, BC807-25W delivers superior density (SOT323), higher guaranteed hFE ceiling (400 vs. 300), and −45 V breakdown - making it optimal for next-gen wearables and compact industrial controllers where size, gain stability, and voltage margin are co-critical.

FAQ
What is the maximum allowable base current for BC807-25W?
The absolute maximum peak base current is −200 mA per Table 6 (Limiting Values). However, for reliable continuous operation at IC = −500 mA, the recommended base current is −50 mA (IC/IB = 10), ensuring deep saturation without exceeding thermal limits or degrading hFE stability over time.
Can BC807-25W replace BC807-16W in an existing design?
Yes - BC807-25W is a direct drop-in replacement for BC807-16W in the same SOT323 package, with identical pinout and voltage/current ratings. Its higher minimum hFE (160 vs. 100) improves bias stability in amplifier circuits but may require minor resistor value adjustment in critical gain-setting networks.
Is BC807-25W qualified for automotive applications?
No. Per Revision History (Section 13), BC807W_SER v.8 explicitly states "Product(s) changed to non-automotive qualification" as of July 2022. Automotive-grade alternatives (e.g., BC807-25Q) must be selected for AEC-Q101-compliant designs; BC807-25W is intended for industrial, consumer, and computing applications only.
What is the thermal resistance (Rth(j-a)) under standard PCB mounting?
When mounted on an FR4 PCB with single-sided copper, tin-plated, and standard footprint (no extended collector pad), Rth(j-a) is 625 K/W per Table 7. This value increases significantly above 25 °C ambient, requiring derating to 200 mW at 75 °C ambient per Figure 1.
