Product details

Overview

BC807-25-7 from Diodes Incorporated is a 45V PNP small-signal transistor in SOT23 package, optimized for switching and audio-frequency amplifier applications. It delivers h_FE = 160–250 at I_C = −100 mA, V_CE = −1.0 V; V_CE(sat) ≤ −0.7 V at I_C = −500 mA/I_B = −50 mA; f_T = 100 MHz; and operates across −55°C to +150°C. Used in discrete logic-level translators and load-switching stages of industrial control modules.

For engineers reviewing the BC807-25-7 datasheet, BC807-25-7 pinout, BC807-25-7 application, or BC807-25-7 equivalent, key selection criteria include guaranteed h_FE binning (−25 variant), low saturation voltage under high-current drive, thermal robustness on FR4 PCBs, and RoHS-compliant green packaging with J-STD-020 Level 1 moisture sensitivity.

Technical Context

This PNP bipolar junction transistor employs epitaxial planar die construction for stable gain and low leakage. Its complementary NPN counterpart is BC817-25, enabling matched pair design in push-pull amplifiers and differential stages.

The device supports pulsed operation up to 1.0 A peak collector current with 2% duty cycle, and exhibits 12 pF collector-base capacitance at V_CB = −10 V, making it suitable for <100 MHz signal routing where capacitive loading must be minimized.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−45 V: Maximum safe collector-emitter voltage before breakdown in common-emitter configuration.
h_FE (I_C = −100 mA)	160–250: Guaranteed DC current gain range for reliable base-drive sizing in linear and saturated switching modes.
V_CE(sat)	≤ −0.7 V at I_C/I_B = −500/−50 mA: Enables low-loss switching in 3.3 V–5 V logic-controlled loads.
f_T	100 MHz: Supports AF amplification and fast digital edge handling up to ~10 MHz square waves.
P_D	310 mW (FR4, min pad): Thermal limit on standard PCB layout without heatsinking or airflow.
ESD HBM	4,000 V: Robust handling during board assembly and bench testing without special ESD precautions.

Pinout & Package

Package: SOT23 - surface-mount plastic package with matte tin-plated leads, 0.008 g mass, UL 94V-0 rated molding compound, and J-STD-020 Level 1 moisture sensitivity.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Current sink terminal	Connected to higher potential rail in PNP switch; sets reference for base bias network.
2 (Base)	Control input	Receives current-limited drive (e.g., via 10 kΩ resistor) to saturate or cut off collector current.
3 (Collector)	Output current path	Drives load to ground when active; requires external pull-up or connected to supply via load.

Key Features

Feature	Design Value
Epitaxial planar die construction	Ensures consistent h_FE distribution and low leakage (I_CES ≤ −5.0 µA at 150°C).
Green, halogen-free package	Meets RoHS 3 (2015/863/EU) and automotive environmental standards with Br+Cl < 1500 ppm.
Automated insertion compatibility	SOT23 footprint and lead geometry support high-speed pick-and-place placement and reflow soldering.
Complementary NPN pairing	Direct functional match with BC817-25 enables balanced push-pull output stages without gain mismatch.

Applications

Industrial Sensor Interface

IC Role / Device Role / Timing Role: Output stage current amplifier in discrete headphone driver circuit.

Use Value: 100 MHz f_T preserves audio bandwidth up to 20 kHz; low V_CE(sat) minimizes heat generation at 100–300 mA quiescent current.

PLC Digital Output Module

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP small-signal transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC807-25-7-F (Diodes)	Same die, identical h_FE binning and electrical specs; differs only in tape/reel marking (K5B vs K5B-F).	No functional difference; both qualified for industrial use; -F suffix denotes fully RoHS-compliant finish.	Select -F version for traceability and compliance documentation in regulated OEM programs.
MMBT3906LT1G (ON Semiconductor)	Lower h_FE (100–300 vs 160–250), higher V_CE(sat) (−0.4 V typ. @ −10 mA, but −1.0 V @ −500 mA), same SOT23 package.	Less suitable for high-current saturation; better for low-power bias networks than load switching.	Prefer BC807-25-7 where guaranteed high h_FE and low V_CE(sat) at ≥300 mA are required.

Compared with MMBT3906LT1G and BC807-25-7-F, the BC807-25-7 offers tighter h_FE binning and lower saturation voltage at high current-critical for efficient load switching-while maintaining identical SOT23 mechanical compatibility and automotive-grade thermal performance.

FAQ

What is the maximum continuous collector current rating for BC807-25-7?

The absolute maximum continuous collector current (I_C) is −0.5 A at T_A = +25°C. Derating applies above 25°C: power dissipation drops linearly to zero at 150°C ambient, per the published derating curve. This rating assumes operation within the SOA limits defined in the datasheet, including V_CE and pulse conditions.

Is BC807-25-7 suitable for automotive applications?

The standard BC807-25-7 is not AEC-Q101 qualified. However, Diodes offers the automotive-grade BC807-40Q variant (separate datasheet) with extended temperature validation, enhanced process controls, and PPAP documentation. For non-safety-critical 12 V body electronics, BC807-25-7 may be used subject to internal qualification-but not for airbag, braking, or ADAS systems.

How does the h_FE binning of BC807-25-7 differ from BC807-16 and BC807-40?

BC807-25-7 is binned for h_FE = 160–250 at I_C = −100 mA/V_CE = −1.0 V, whereas BC807-16 covers 100–160 and BC807-40 covers 250–600. This allows designers to select precise gain ranges for bias stability, noise performance, or current mirror accuracy without post-manufacturing sorting.

Can BC807-25-7 replace BC807-25 in existing designs?

Yes-BC807-25-7 is functionally identical to BC807-25, differing only in packaging format (7-inch reel, 3,000 pcs) and marking (K5B). Electrical, thermal, and mechanical specifications are fully aligned. No layout or schematic changes are needed; the "-7" suffix denotes tape-and-reel configuration, not a parametric revision.
