Product details

Overview

BC807-25B5003 from Nexperia is a PNP silicon general-purpose audio-frequency transistor with h_FE = 160–250 at I_C = 100 mA, V_CE = 1 V; V_CEO = 45 V; I_C = 500 mA continuous; V_CE(sat) ≤ 0.7 V at I_C = 500 mA, I_B = 50 mA; packaged in SOT23. It serves as a low-voltage switching and linear amplification device in power management and signal conditioning stages of industrial control modules.

For engineers reviewing the BC807-25B5003 datasheet, BC807-25B5003 pinout, BC807-25B5003 application, or BC807-25B5003 equivalent, key selection criteria include DC current gain group (h_FE-grp. 25), thermal resistance (R_thJS ≤ 215 K/W), saturation voltage performance under high-current drive, and AEC-Q101 qualification for automotive-grade reliability.

Technical Context

This PNP bipolar junction transistor operates in active, saturation, and cutoff regions for analog amplification and digital switching. Its h_FE group 25 ensures predictable current amplification across I_C = 10 mA to 500 mA at V_CE = 1 V, with f_T = 200 MHz enabling stable operation up to mid-RF frequencies in oscillator and driver circuits.

Designed for surface-mount use in space-constrained PCBs, it features complementary NPN pairing with BC817-25/BC817-25W and meets RoHS compliance with Pb-free SOT23 packaging. Thermal derating follows a defined P_tot vs. T_S curve, supporting reliable operation up to T_j = 150 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	45 V - Maximum safe collector-emitter voltage before breakdown in open-base configuration
I_C (continuous)	500 mA - Continuous collector current rating defining usable load-driving capability
h_FE (min–max)	160–250 at I_C = 100 mA, V_CE = 1 V - Confirmed DC current gain range for bias design and gain stability
V_CE(sat)	≤ 0.7 V at I_C = 500 mA, I_B = 50 mA - Low saturation voltage enables efficient switching with minimal conduction loss
f_T	200 MHz - Transition frequency confirming suitability for AF and low-MHz signal amplification
R_thJS	≤ 215 K/W - Junction-to-soldering-point thermal resistance guiding heatsinking and layout decisions

Use Value: Tight h_FE grouping (160–250) and low I_CBO (<0.1 µA) ensure stable current ratio and low offset drift over temperature.

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
BC807-25,115 (Nexperia)	Same die, identical h_FE group and electrical specs; differs only in tape-and-reel packaging code	No functional difference; suitable for identical PCB layouts and thermal environments	Select when standard reel packaging (10,000 pcs/reel) is required instead of custom B5003 variant
MMBT807 (ON Semiconductor)	h_FE min = 100 (vs. 160), V_CEO = 45 V, R_thJS = 250 K/W - lower gain and higher thermal resistance	Acceptable in non-critical switching where base drive margin exists; not recommended for precision current mirrors	Choose only if BC807-25B5003 is unavailable and design allows 40% h_FE reduction and 16% thermal penalty

Compared with BC807-25B5003, BC807-25,115 offers identical performance in standard packaging, while MMBT807 trades gain and thermal efficiency for broader legacy availability-making the former ideal for drop-in continuity and the latter a fallback requiring design validation.

FAQ

Is BC807-25B5003 pin-compatible with BC807-25,115?

Yes, BC807-25B5003 and BC807-25,115 share identical SOT23 pinout (Emitter–Base–Collector on pins 1–2–3), same die, and identical electrical specifications. The "B5003" suffix denotes a specific tape-and-reel packaging configuration (e.g., 3,000 pcs/reel, custom orientation), not a functional variant.

What is the maximum allowable base current for continuous operation?

The absolute maximum rated base current is 100 mA, but for reliable continuous operation with I_C = 500 mA, the datasheet specifies I_B = 50 mA to achieve V_CE(sat) ≤ 0.7 V. Exceeding 50 mA does not improve saturation and risks accelerated degradation under thermal stress.

Can BC807-25B5003 replace BC808-25 in a 25 V circuit?

No-BC808-25 has V_CEO = 25 V and is optimized for lower-voltage systems. BC807-25B5003 has V_CEO = 45 V and higher leakage (I_CBO) at elevated voltage. Substituting it into a 25 V design may cause unnecessary overdesign and mismatched h_FE temperature behavior.

Does BC807-25B5003 support pulsed operation beyond 500 mA?

Yes-peak collector current I_CM is rated at 1000 mA for pulse widths <300 µs and duty cycle <2%. This enables short-duration surge handling in motor commutation or ESD protection clamping, provided average power remains within P_tot = 330 mW limits.
