Product details
Overview
BC807K-25R from Nexperia is a PNP general-purpose bipolar junction transistor (BJT) in SOT23 (TO-236AB) package, rated for −45 V collector-emitter voltage, −500 mA continuous collector current, and DC current gain (hFE) of 160–400 at VCE = −1 V and IC = −100 mA. It serves as a low-voltage switching or linear amplification device in automotive body control modules, industrial sensor interface circuits, and power supply enable stages.
For engineers reviewing the BC807K-25R datasheet, BC807K-25R pinout, BC807K-25R application, or BC807K-25R equivalent, this page delivers verified electrical parameters, thermal derating behavior, AEC-Q101 qualification status, and real-world implementation guidance for discrete PNP switching in space-constrained PCB designs.
Technical Context
This PNP BJT operates in active, saturation, and cutoff regions with defined breakdown limits: VCEO = −45 V, VCBO = −50 V, and VEBO = −5 V. Its pulsed peak collector current reaches −1 A (tp ≤ 1 ms), supporting short-duration load switching.
Thermal performance depends on PCB layout: Rth(j-a) ranges from 157 K/W (4-layer copper, 1 cm² collector pad) to 358 K/W (single-sided FR4, standard footprint). Junction temperature is rated to 150 °C, with storage spanning −65 °C to 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −45 V - Maximum safe collector-emitter voltage with base open; defines upper rail limit in high-side switch configurations. |
| IC | −500 mA - Continuous DC collector current rating; sets maximum steady-state load drive capability. |
| hFE | 160–400 - DC current gain at VCE = −1 V, IC = −100 mA; determines required base drive for reliable saturation. |
| VCE(sat) | −700 mV max at IC = −500 mA, IB = −50 mA - Low saturation voltage minimizes conduction loss in switching applications. |
| fT | 80 MHz - Transition frequency at VCE = −5 V, IC = −10 mA; supports audio-frequency amplification and fast digital switching. |
| Ptot | 800 mW - Maximum total power dissipation on 4-layer FR4 with 1 cm² collector pad; guides thermal layout decisions. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-pin, 1.3 mm × 2.9 mm footprint, 1.1 mm height, lead pitch 0.95 mm. RoHS-compliant, halogen-free, qualified per AEC-Q101.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Current-controlled input node; requires ≥−50 mA drive for full saturation at −500 mA collector load. |
| 2 | Emitter (E) | Common reference terminal; connected to higher potential rail in high-side switch topologies. |
| 3 | Collector (C) | Output current path; electrically tied to PCB copper pour for thermal management in power switching. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood and cabin applications including BCMs and lighting control units. |
| Three hFE bins (−16/−25/−40) | Enables precise base resistor selection across production lots without redesigning bias networks. |
| High Ptot (800 mW) | Supports sustained 500 mA loads on thermally optimized 4-layer boards without external heatsinking. |
| Low VBE(sat) (−1.2 V max) | Reduces base drive power requirement and eases compatibility with 3.3 V or 5 V logic-level controllers. |
Applications
| Automotive Body Control Module | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Driving resistive loads such as door lock actuators or HVAC damper solenoids in 12 V systems. IC Role / Device Role / Timing Role: High-side PNP switch enabling ground-referenced load control with microcontroller GPIO. Use Value: −45 V VCEO withstands load dump transients; AEC-Q101 ensures reliability over 15-year vehicle lifetime. |

IC Role / Device Role / Timing Role: Linear amplifier in common-emitter configuration with stable hFE across −40 °C to +125 °C. Use Value: 80 MHz fT preserves signal integrity up to 10 kHz; low Cc (7 pF) minimizes capacitive loading on sensitive nodes. |
| DC-DC Converter Enable Circuit | LED Driver for Status Indication |

Use Value: Tight hFE bin (160–400) enables ±5% LED current tolerance without feedback; −500 mA rating supports multi-LED strings. |
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 | No AEC-Q101 qualification; identical hFE, VCEO, and IC ratings; same SOT23 package. | Not suitable for automotive environments; acceptable for commercial-grade consumer or industrial control. | Select when automotive qualification is unnecessary and cost sensitivity outweighs long-term reliability requirements. |
| MMBT3906LT1G | Lower IC (−200 mA), lower VCEO (−40 V), hFE 100–300; SOT23 package with compatible pinout. | Limited to low-power signal switching; insufficient for 500 mA loads or 12 V automotive rails with transients. | Choose only for space-constrained, low-current (<200 mA), non-automotive applications where footprint compatibility is critical. |
Compared with BC807-25 and MMBT3906LT1G, BC807K-25R provides guaranteed automotive qualification, higher current handling, and tighter hFE distribution-making it the sole choice for safety-critical or high-reliability PNP switching where transient immunity and lifetime stability are mandatory.

FAQ
What is the maximum allowable junction temperature for BC807K-25R?
The absolute maximum junction temperature (Tj) is 150 °C. Operation above this value risks permanent degradation of hFE, increased leakage, and bond wire failure. Thermal design must ensure Tj remains below 150 °C under worst-case ambient and power dissipation conditions, using the appropriate Rth(j-a) value for the actual PCB construction.
Is BC807K-25R pin-compatible with BC807-25?
Yes-both use identical SOT23 (TO-236AB) packaging with pin 1 = Base, pin 2 = Emitter, pin 3 = Collector. Mechanical and solder footprint compatibility is confirmed per Figures 43–45 in the datasheet. However, BC807K-25R adds AEC-Q101 qualification and tighter process controls not present in the standard BC807-25.
Can BC807K-25R be used in linear amplifier configurations?
Yes-it exhibits stable hFE from −55 °C to +150 °C and low VBE variation (±0.1 V typical across IC range), supporting Class-A and AB amplifier stages. For best linearity, bias at VCE ≈ −1 V and IC = −10 mA to −100 mA, where hFE is most consistent and fT remains >50 MHz.
What is the meaning of the 'K' suffix in BC807K-25R?
The 'K' denotes Nexperia's automotive-grade product family, indicating full AEC-Q101 qualification, extended temperature operation (−55 °C to +150 °C), and enhanced process controls for zero-defect manufacturing. The 'R' suffix indicates tape-and-reel packaging (3000 pcs/reel), standard for SMT assembly.
