Product details

Overview

BC807-25W-QF from Nexperia is a PNP general-purpose bipolar junction transistor in SOT323 (SC-70) package, rated for −45 V V_CEO, −500 mA I_C, and DC current gain (h_FE) of 160–400 at V_CE = −1 V and I_C = −100 mA. It delivers low V_CE(sat) of −700 mV at I_C = −500 mA / I_B = −50 mA and supports automotive-grade operation per AEC-Q101.

For engineers reviewing the BC807-25W-QF datasheet, BC807-25W-QF pinout, BC807-25W-QF application, or BC807-25W-QF equivalent, this device is selected for compact, high-reliability switching in automotive body control modules, LED driver bias networks, and low-voltage power rail enable circuits where precise current gain binning and thermal robustness are required.

Technical Context

This PNP BJT operates with open-base collector-emitter breakdown voltage of −45 V and emitter-base breakdown voltage of −5 V, enabling safe use in 12 V and 24 V automotive supply rails. Its pulsed peak collector current capability reaches −1 A (t_p ≤ 1 ms), supporting transient load switching without secondary breakdown concerns.

The device exhibits a transition frequency (f_T) of 80 MHz at V_CE = −5 V, I_C = −10 mA, confirming suitability for low-speed digital switching and audio-frequency amplification. Thermal resistance R_th(j-a) is 431 K/W when mounted on FR4 PCB with 1 cm² collector pad, aligning with space-constrained board layouts requiring passive thermal management.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−45 V - Maximum safe collector-emitter voltage under open-base condition; defines rail compatibility with 36 V automotive systems.
I_C	−500 mA - Continuous DC collector current rating; supports medium-power load switching (e.g., relays, small solenoids).
h_FE	160–400 - Guaranteed DC current gain range at V_CE = −1 V, I_C = −100 mA; enables predictable base drive sizing in linear and saturated modes.
V_CE(sat)	−700 mV - Collector-emitter saturation voltage at I_C = −500 mA / I_B = −50 mA; limits conduction loss to < 350 mW in switch applications.
f_T	80 MHz - Transition frequency at V_CE = −5 V, I_C = −10 mA; confirms adequate bandwidth for PWM-driven loads up to ~5 MHz.
P_tot	290 mW - Total power dissipation with 1 cm² copper pad; sets practical thermal limit for continuous operation at ambient ≤ 85 °C.

Pinout & Package

SOT323 (SC-70) plastic surface-mounted package: ultra-compact 3-lead outline measuring 2.2 mm × 1.35 mm × 0.95 mm (L × W × H), optimized for high-density PCB layouts and reflow soldering.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Control terminal accepting forward-biased current to turn on PNP conduction; requires external current-limiting resistor for TTL/CMOS drive compatibility.
2	Emitter (E)	Current source terminal connected to higher potential rail; serves as reference node for bias network design and thermal path to PCB copper.
3	Collector (C)	Current sink terminal connected to load; layout must allocate ≥1 cm² copper area for thermal relief per datasheet derating curve.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive applications including engine control units and lighting modules; supports 15-year service life under thermal cycling and humidity stress.
Three h_FE bins	BC807-25W-QF provides mid-range gain (160–400), enabling consistent switching thresholds across production batches without recalibration.
Low V_CE(sat)	−700 mV at full rated current ensures < 0.35 W conduction loss, reducing thermal load in sealed enclosures and improving system efficiency.
SOT323 footprint	Standardized SC-70 land pattern (2.65 mm × 2.35 mm solder mask opening) enables drop-in replacement and compatibility with automated placement equipment.

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
BC807-25LT1G	Same h_FE bin (160–400) but SOT-23 package; 300 mW P_tot; no AEC-Q101 qualification.	Limited to commercial-temperature industrial use; unsuitable for automotive under-hood environments.	Select when cost sensitivity outweighs automotive qualification and thermal performance requirements.
MMBT3906LT1G	Lower V_CEO (−40 V); h_FE 100–300; same SOT-23; AEC-Q101 qualified only in specific variants.	Marginally insufficient for 24 V load-dump immunity; gain spread increases base resistor tolerance sensitivity.	Choose only if existing design uses MMBT3906 footprint and V_CEO margin is verified above −40 V.

Compared with BC807-25W-QF, BC807-25LT1G trades automotive reliability for lower cost and wider distributor availability, while MMBT3906LT1G sacrifices voltage headroom and gain consistency-making BC807-25W-QF optimal for new automotive and thermally constrained designs requiring guaranteed h_FE and transient robustness.

FAQ

What is the maximum allowable junction temperature for BC807-25W-QF?

The absolute maximum junction temperature (T_j) is 150 °C, as defined in the Absolute Maximum Ratings table. Operation beyond this limit risks permanent degradation of h_FE and increased leakage. Derating curves in Figure 1 confirm usable power dissipation drops to zero at 150 °C ambient when mounted on standard FR4 PCB.

Can BC807-25W-QF replace BC807-16W-QF in an existing design?

Yes, with verification of gain-dependent circuit behavior. BC807-25W-QF has higher minimum h_FE (160 vs. 100) and narrower gain range than BC807-16W-QF (100–250). This may reduce required base drive current but could affect saturation depth in high-current switching-confirm V_CE(sat) and switching speed under actual load conditions.

Is the SOT323 package lead-free and RoHS compliant?

Yes. BC807-25W-QF is manufactured with lead-free terminations and complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The "QF" suffix denotes Nexperia's qualified automotive-grade variant with full material declaration and process control documentation.

How does the AEC-Q101 qualification impact BC807-25W-QF's test coverage?

AEC-Q101 qualification requires passing stress tests including HTGB (high-temperature gate bias), AC/DC life testing, ESD (HBM ≥ 2 kV), and temperature cycling (−40 °C to +125 °C for 1000 cycles). These validate reliability for automotive under-hood applications, not just compliance with commercial-grade JEDEC standards.
