Product details
Overview
BC807-25H-QR from Nexperia is a PNP general-purpose bipolar junction transistor in SOT23 package, rated for −45 V VCEO, −500 mA continuous collector current, and DC current gain (hFE) of 160–400 at VCE = −1 V and IC = −100 mA. It operates reliably up to 175 °C and is AEC-Q101 qualified for automotive under-hood switching and signal amplification.
For engineers reviewing the BC807-25H-QR datasheet, BC807-25H-QR pinout, BC807-25H-QR application, or BC807-25H-QR equivalent, this page delivers verified electrical parameters, thermal derating behavior, automotive qualification status, and real-world switching performance under pulsed and DC conditions - all critical for robust discrete BJT selection in safety-conscious designs.
Technical Context
This PNP transistor uses epitaxial planar technology with optimized base doping and geometry to achieve high hFE consistency across temperature (−55 °C to +175 °C) and stable VCE(sat) ≤ −700 mV at IC = −500 mA / IB = −50 mA. Its low Cc (7 pF typical) and Ce (45 pF typical) support moderate-frequency switching up to 80 MHz fT.
The device complies with IEC 60134 absolute maximum ratings, features guaranteed breakdown voltages (VCBO = −50 V, VEBO = −7 V), and exhibits low leakage (ICBO ≤ −100 nA at 25 °C). Thermal resistance Rth(j-a) ranges from 280 K/W (4-layer PCB, 1 cm² collector pad) to 470 K/W (standard FR4 single-sided layout), enabling precise thermal design in constrained spaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −45 V - Maximum safe collector-emitter voltage with open base; defines off-state blocking capability in high-side switch configurations. |
| IC (continuous) | −500 mA - Continuous DC collector current at 25 °C ambient; sets baseline load-driving capacity for logic-level interfacing and driver stages. |
| hFE | 160–400 - DC current gain range at VCE = −1 V, IC = −100 mA; ensures predictable base drive requirements across production lots and temperature. |
| VCE(sat) | ≤ −700 mV - Collector-emitter saturation voltage at IC = −500 mA / IB = −50 mA; directly determines conduction loss and heat generation in saturated switching. |
| fT | 80 MHz - Transition frequency at VCE = −5 V, IC = −10 mA; indicates usable bandwidth for small-signal amplification and medium-speed digital switching. |
| Rth(j-a) | 280–470 K/W - Junction-to-ambient thermal resistance depending on PCB copper layer count and collector pad area; enables accurate junction temperature estimation in thermal-aware layouts. |
| AEC-Q101 | Qualified - Certified for automotive applications per Stress Test Qualification for Discrete Semiconductors; supports use in engine control, body electronics, and ADAS subsystems. |
Pinout & Package
SOT23 plastic surface-mounted package (TO-236AB); 3-lead, 1.3 mm × 2.9 mm footprint with 0.95 mm height; standard reflow-compatible outline per Fig. 43 in datasheet Rev. 1 (2023).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control terminal for forward-biased PNP operation; requires negative base current relative to emitter to turn on. |
| 2 | Emitter (E) | Current source terminal in PNP configuration; connected to higher potential rail in high-side switch topologies. |
| 3 | Collector (C) | 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-Q (100–250), BC807-25H-Q (160–400), BC807-40H-Q (250–600) - Enables precise gain matching for analog biasing and consistent switching thresholds across production. |
| High-temperature operation | Junction temperature rating up to 175 °C - Supports placement near heat sources (e.g., power converters, motor drivers) without derating or thermal shutdown. |
| AEC-Q101 qualification | Stress-tested per automotive discrete semiconductor standard - Validates reliability for 15+ year service life in automotive ECUs and lighting modules. |
| Low VBE(sat) | ≤ −1.2 V at IC = −500 mA / IB = −50 mA - Reduces base drive power dissipation and simplifies level-shifting circuitry in microcontroller-driven switches. |
| Controlled capacitance | Cc = 7 pF, Ce = 45 pF - Limits Miller effect and switching delay in <10 MHz digital applications while maintaining stability in linear amplifiers. |

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 |
|---|---|---|---|
| BC807-25-7-F (Diodes Inc.) | Same SOT23 package, hFE 160–400, but VCEO = −45 V and VCE(sat) = −0.7 V max at IC = −500 mA - identical electrical envelope. | Not AEC-Q101 qualified; suitable for industrial/commercial but not automotive deployment. | Select when AEC-Q101 is not required and cost sensitivity outweighs automotive compliance. |
| MMBT3906LT1G (ON Semiconductor) | hFE 100–300 (lower gain spread), VCEO = −40 V, VCE(sat) = −0.4 V max at IC = −100 mA - reduced voltage margin and narrower gain band. | Limited to ≤40 V systems; less suitable for automotive 12 V/24 V load-dump scenarios requiring −45 V headroom. | Choose only for legacy designs where MMBT3906 footprint compatibility is mandatory and voltage margin is sufficient. |
Compared with BC807-25H-QR, BC807-25-7-F offers identical performance without automotive qualification, while MMBT3906LT1G trades gain consistency and voltage rating for broader legacy availability - making BC807-25H-QR the optimal choice for new AEC-Q101-compliant designs demanding guaranteed hFE and transient robustness.

FAQ
What is the maximum allowable junction temperature for BC807-25H-QR?
The absolute maximum junction temperature is 175 °C, validated per AEC-Q101 stress testing. Operation at this limit requires careful thermal design using the specified Rth(j-a) values (280–470 K/W) and appropriate PCB copper area. Derating curves in Figure 1 confirm continuous power dissipation drops linearly above 25 °C ambient.
Is BC807-25H-QR pin-compatible with BC807-25 or BC807-25W variants?
Yes - all BC807-25x variants use the same SOT23 (TO-236AB) package with identical pin 1–2–3 assignment (B–E–C). However, BC807-25H-QR has tighter hFE binning (160–400) and full AEC-Q101 qualification, unlike non-Q or non-H suffix versions which may lack automotive testing or gain grading.
How does BC807-25H-QR perform in pulsed switching applications?
It supports peak collector current up to −1 A for pulses ≤1 ms (duty cycle ≤0.02), with safe operating area (SOA) defined in Figure 2. At IC = −500 mA and IB = −50 mA, VCE(sat) remains ≤−700 mV, minimizing pulse energy loss. Transient thermal impedance data (Fig. 3–6) confirms effective heat dissipation during short bursts.
Can BC807-25H-QR replace BC807-40H-QR in a design?
No - BC807-40H-QR has higher hFE (250–600) and lower VCE(sat) at light loads, but BC807-25H-QR provides better gain stability at high current (≥300 mA) and superior thermal performance due to optimized doping. Substitution requires verification of base drive capability and gain-dependent loop stability in analog circuits.
