Product details
Overview
BC806-25H-QR from Nexperia is a PNP general-purpose bipolar junction transistor in SOT23 package, rated for −80 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 and is AEC-Q101 qualified for automotive board-net switching.
For engineers reviewing the BC806-25H-QR datasheet, BC806-25H-QR pinout, BC806-25H-QR application, or BC806-25H-QR equivalent, key selection criteria include its high-voltage PNP switching capability, thermal robustness in 48 V automotive systems, and verified hFE binning for consistent bias design.
Technical Context
This discrete PNP transistor delivers stable current amplification and switching performance across −55 °C to +175 °C ambient, with VCE(sat) ≤ −400 mV at IC = −500 mA and IB = −50 mA. Its low Cc (5 pF typ.) and Ce (47 pF typ.) support moderate-frequency switching up to 80 MHz fT.
The device uses standard SOT23 leadframe construction with tin-plated terminations, optimized for reflow soldering on FR4 PCBs. Thermal resistance Rth(j-a) is 500 K/W (standard footprint) or 363 K/W (1 cm² collector pad), enabling reliable power dissipation up to 300 mW at 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −80 V: Maximum safe collector-emitter voltage under open-base condition; enables use in 48 V automotive supply rails with margin. |
| IC | −500 mA continuous: Rated collector current defines maximum steady-state load drive capability in linear or saturated operation. |
| hFE | 160–400 at VCE = −1 V, IC = −100 mA: Tight DC current gain bin ensures predictable base drive requirements for bias networks. |
| VCE(sat) | ≤ −400 mV at IC = −500 mA, IB = −50 mA: Low saturation voltage minimizes conduction loss in high-current switching applications. |
| Tj(max) | +175 °C: Junction temperature rating supports operation in under-hood automotive environments without derating below 125 °C ambient. |
| fT | 80 MHz: Transition frequency confirms suitability for signal amplification and switching up to mid-MHz frequencies. |
| Rth(j-a) | 500 K/W (standard PCB): Thermal resistance determines required board copper area for thermal management in compact layouts. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package with gull-wing leads, 1.3 mm body height, and 2.1–2.5 mm length per JEDEC outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control terminal; requires current-limited drive to achieve specified hFE and VCE(sat) performance. |
| 2 | Emitter (E) | Common reference terminal for PNP configuration; connected to higher potential rail in high-side switch topologies. |
| 3 | Collector (C) | Current output terminal; handles full load current and dissipates power during switching transitions. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing-enables direct use in ASIL-B supporting circuits. |
| High-temperature operation | Rated for continuous operation up to +175 °C junction temperature-eliminates need for external thermal derating in engine-control modules. |
| Two hFE bins | BC806-25H-Q offers 160–400 hFE, distinct from BC806-16H-Q (100–250); allows precise gain matching in differential or feedback amplifier designs. |
| Low VBE variation | VBE ≤ −1.2 V at IC = −500 mA ensures stable base drive voltage across temperature and process spread. |
| Standard SOT23 footprint | Compatible with industry-standard reflow and wave soldering profiles-reduces manufacturing changeover cost and supports automated assembly. |
Applications
| Automotive Load Switching | 48 V Board-Network Regulation |
|---|---|

IC Role / Device Role / Timing Role: Discrete PNP switch enabling controlled power-up sequencing and fault-isolation logic. Use Value: 175 °C Tj(max) sustains operation near battery cells; tight hFE bin reduces base-drive component tolerance stack-up. |
| Industrial Sensor Interface | Consumer Power Management |
|

IC Role / Device Role / Timing Role: Linear-mode PNP amplifier stage providing current gain before ADC input conditioning. Use Value: Stable hFE across −55 °C to +125 °C ambient ensures consistent gain calibration without software compensation. |
Use Scenario: Enabling/disabling auxiliary power rails in smart home hubs with strict BOM cost targets and size limits. IC Role / Device Role / Timing Role: Low-cost discrete switch replacing integrated load switches where programmability is unnecessary. Use Value: SOT23 footprint saves >40% PCB area vs. SO-8 alternatives; −400 mV VCE(sat) keeps self-heating below 100 mW at 300 mA load. |
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 |
|---|---|---|---|
| BC806-16H-Q | Lower hFE range (100–250) and identical VCEO/IC ratings. | Preferred where lower gain reduces risk of unintended oscillation in high-impedance sensor interfaces. | Select when base drive current budget is constrained and gain stability at low IC is prioritized over maximum current amplification. |
| BC816-25H-Q | NPN complement with same VCEO, IC, hFE, and AEC-Q101 qualification. | Used in low-side switching configurations where emitter grounding simplifies PCB layout and controller interfacing. | Choose for complementary pair designs or when existing NPN-based schematics require direct substitution without topology change. |
Compared with BC806-16H-Q, BC806-25H-Q provides higher and more tightly binned hFE for improved bias predictability; versus BC816-25H-Q, it enables high-side switching but requires inverted logic drive and careful ground-referenced sensing.

FAQ
Is BC806-25H-QR pin-compatible with BC806-16H-Q?
Yes-both share identical SOT23 pinout (1: Base, 2: Emitter, 3: Collector) and mechanical footprint. The only functional difference is hFE binning; no PCB redesign is needed when upgrading from BC806-16H-Q to BC806-25H-QR for improved gain consistency.
What is the maximum allowable power dissipation at 100 °C ambient?
At Tamb = 100 °C, Ptot must be derated linearly from 300 mW (25 °C) using the 500 K/W Rth(j-a). This yields Ptot = 300 mW × (1 − (100 − 25)/500) = 150 mW. Exceeding this risks junction temperature exceeding 175 °C.
Does BC806-25H-QR support pulse operation beyond 500 mA?
Yes-peak collector current ICM is rated at −1 A for single pulses ≤1 ms. However, VCE(sat) rises to −1 V under these conditions, and thermal limits still apply; sustained operation above −500 mA requires active cooling or reduced duty cycle.
Can BC806-25H-QR replace BC807-25 in existing designs?
No-BC807-25 is an NPN transistor with opposite polarity and complementary pinout (1: Emitter, 2: Base, 3: Collector). Substitution would invert logic and require PCB rewiring; BC816-25H-Q is the correct NPN counterpart for BC806-25H-QR.
