Product details
Overview
BC807-25HZ from Nexperia is a PNP general-purpose bipolar junction transistor (BJT) in SOT23 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 operates up to 175 °C junction temperature and is used in low-voltage switching and linear amplification circuits such as power supply enable control and sensor interface stages.
For engineers reviewing the BC807-25HZ datasheet, BC807-25HZ pinout, BC807-25HZ application, or BC807-25HZ equivalent, key selection criteria include its −45 V collector-emitter breakdown voltage, thermal robustness to 175 °C, SOT23 footprint compatibility, and hFE range optimized for stable biasing in discrete amplifier and switch designs.
Technical Context
This PNP BJT features a planar epitaxial silicon structure with emitter ballasting for improved current sharing and thermal stability. Its base-emitter saturation voltage is specified at −1.2 V (max) under IC = −500 mA / IB = −50 mA conditions, enabling predictable turn-on behavior in saturated-switch applications.
The device exhibits fT = 80 MHz at VCE = −5 V, IC = −10 mA, supporting moderate-frequency signal amplification. Capacitance values-Cc = 7 pF (typ) and Ce = 45 pF (typ) at 1 MHz-reflect its suitability for audio and low-speed digital switching rather than RF operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −45 V: Maximum safe collector-emitter voltage with open base; defines upper rail limit in PNP switch configurations. |
| IC | −500 mA continuous: Rated collector current at 25 °C ambient; derates above 25 °C per thermal resistance curves. |
| hFE | 160–400 at VCE = −1 V, IC = −100 mA: Ensures reliable DC bias stability across production lots and temperature. |
| VCE(sat) | −700 mV max at IC = −500 mA, IB = −50 mA: Low saturation voltage minimizes conduction loss in high-current switching. |
| Tj(max) | 175 °C: Enables use in high-temperature industrial environments without derating penalties typical of lower-rated transistors. |
| Ptot | 540 mW on 4-layer FR4 PCB with 1 cm² collector pad: Defines maximum dissipation under optimized board layout. |
Pinout & Package
SOT23 plastic surface-mount package (TO-236AB), 3-pin, 1.3 mm × 2.9 mm footprint, 1.1 mm height; JEDEC-compliant outline with standard reflow and wave soldering land patterns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - B | Base | Control terminal for forward-biased PNP operation; requires negative base current relative to emitter to turn on. |
| 2 - E | Emitter | Current source terminal in PNP configuration; connected to higher potential rail in common-emitter switch topologies. |
| 3 - C | Collector | Current sink terminal; carries load current to ground or lower-potential node when transistor is saturated. |
Key Features
| Feature | Design Value |
|---|---|
| Three hFE grades | BC807-16H (100–250), BC807-25H (160–400), BC807-40H (250–600): Enables precise gain matching for analog stages and consistent switching thresholds. |
| High-temperature operation | Junction rating up to 175 °C: Supports deployment in engine control units, industrial motor drives, and enclosed power supplies without thermal shutdown. |
| Low VBE(sat) | −1.2 V max at IC = −500 mA: Reduces base drive power requirement and eases design of compact current-limited driver stages. |
| Robust SOA | Peak IC = −1 A (1 ms pulse); VCE = −45 V: Accommodates inductive kickback and surge currents in relay and solenoid drivers. |
Applications
| Power Supply Enable Switch | Microcontroller GPIO Interface |
|---|---|
|
Use Scenario: Enabling/disabling a 12 V auxiliary rail using an MCU's 3.3 V output pin. IC Role / Device Role / Timing Role: PNP switch controlling high-side power path; base driven via current-limiting resistor from MCU. Use Value: −45 V VCEO provides margin against input transients; −700 mV VCE(sat) ensures minimal dropout and heat generation at 300 mA load. |
Use Scenario: Level-shifting and current amplification for driving LED indicators or small relays from low-current microcontroller outputs. IC Role / Device Role / Timing Role: Discrete current buffer between MCU I/O and external load; configured in common-emitter mode. Use Value: hFE ≥ 160 guarantees >10 mA output current with <100 µA base drive; SOT23 footprint saves board space in dense layouts. |
| Industrial Sensor Signal Conditioning | Automotive Body Control Module |
|
Use Scenario: Amplifying weak NTC thermistor signals in HVAC control circuits operating from 5 V rails. IC Role / Device Role / Timing Role: Linear amplifier stage with emitter-follower or common-emitter topology for gain and impedance transformation. Use Value: Stable hFE over −40 °C to +125 °C ensures consistent gain across environmental range; low Ce = 45 pF avoids high-frequency roll-off. |
Use Scenario: Driving door lock actuators and window lift motors in non-safety-critical body electronics modules. IC Role / Device Role / Timing Role: High-reliability discrete switch handling intermittent 400 mA loads with repeated cycling. Use Value: 175 °C Tj(max) supports under-dash mounting; −1 A peak IC rating absorbs motor startup surges without failure. |
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 non-H grade; no guaranteed hFE binning; lower production consistency. | Limited suitability for precision biasing or gain-critical analog stages. | Select BC807-25HZ when hFE consistency and high-temperature reliability are required. |
| MMBT3906LT1G | hFE = 100–300 (lower max), VCEO = −40 V, Ptot = 310 mW on FR4. | Not recommended for 45 V systems or >350 mA continuous loads due to lower voltage and power ratings. | Choose MMBT3906LT1G only for cost-sensitive, low-power, ≤40 V applications where thermal margin is ample. |
Compared with BC807-25 and MMBT3906LT1G, the BC807-25HZ delivers tighter hFE control, higher VCEO margin, and superior thermal capability-making it the preferred choice for industrial-grade switching and amplification where long-term parametric stability matters.

FAQ
Is BC807-25HZ pin-compatible with BC807-25?
Yes, BC807-25HZ uses the identical SOT23 package and pinout (B-E-C) as BC807-25. The "HZ" suffix denotes the H-grade version with guaranteed hFE binning (160–400) and enhanced high-temperature qualification per Rev. 2 datasheet, while maintaining full mechanical and electrical interchangeability.
What is the maximum allowable base current for continuous operation?
The absolute maximum peak base current is −200 mA (single pulse, tp ≤ 1 ms). For continuous DC operation, base current must be limited to ensure junction temperature remains ≤175 °C. With typical hFE ≥ 160, IB ≤ 3.1 mA suffices to drive IC = −500 mA, well within safe thermal limits on standard PCBs.
Can BC807-25HZ replace BC807-40H in a circuit?
No-BC807-25HZ has hFE = 160–400, while BC807-40H is binned to 250–600. Substituting may cause insufficient gain in high-impedance or low-base-drive circuits, leading to incomplete saturation or unstable bias points. Verify hFE requirements before interchanging grades.
Does BC807-25HZ meet automotive AEC-Q101 requirements?
No-per Revision History in the datasheet, BC807H_SER v.2 explicitly states product qualification was changed to non-automotive status. Automotive-grade equivalents (e.g., BC807-25Q) are available separately and qualified to AEC-Q101; BC807-25HZ is intended for industrial and commercial applications only.
