Product details

Overview

BC807-25 B5003 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, and I_C = 500 mA continuous - used in low-voltage switching and linear amplification stages of power management and signal conditioning circuits.

For engineers reviewing the BC807-25 B5003 datasheet, BC807-25 B5003 pinout, BC807-25 B5003 application, or BC807-25 B5003 equivalent, key selection criteria include DC current gain group (h_FE-grp. 25), SOT23 package thermal resistance (R_thJS ≤ 215 K/W), saturation voltage at high drive (V_CEsat ≤ 0.7 V @ I_C = 500 mA / I_B = 50 mA), and AEC-Q101 qualification for automotive-grade reliability.

Technical Context

This PNP bipolar junction transistor operates in active, saturation, and cutoff regions with defined breakdown limits: V_(BR)CEO = 45 V (min), V_(BR)CBO = 50 V (min), and V_(BR)EBO = 5 V (min). Its f_T = 200 MHz (typ) supports mid-frequency amplification up to ~100 MHz with stable h_FE across −40°C to 105°C.

Thermal performance is characterized by R_thJS ≤ 215 K/W (SOT23) and P_tot = 330 mW at T_S ≤ 79°C. The device meets AEC-Q101 stress testing for automotive under-hood applications and is RoHS-compliant with lead-free termination.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	45 V - maximum safe collector-emitter voltage before avalanche in open-base configuration
h_FE (I_C = 100 mA)	160–250 - ensures predictable base drive sizing for 500 mA load switching
V_CEsat (I_C = 500 mA)	≤ 0.7 V - minimizes conduction loss in saturated-switching applications
f_T	200 MHz (typ) - supports stable small-signal amplification up to ~100 MHz
R_thJS	≤ 215 K/W - defines junction-to-solder-point thermal path for SOT23 mounting
P_tot (T_S ≤ 79°C)	330 mW - sets absolute power limit before thermal derating begins
AEC-Q101 Qualified	Yes - validated for automotive temperature cycling, HTRB, and ESD robustness

Pinout & Package

BC807-25 B5003 is housed in a standard SOT23 plastic surface-mount package with gull-wing leads and JEDEC MO-215 outline compliance.

Pin/Terminal	Circuit Role	Design Meaning

Key Features

Feature	Design Value

Use Scenario: Switching 350 mA LED string in rear combination lamp with PWM dimming.

IC Role / Device Role / Timing Role: PNP current sink switch controlled by microcontroller GPIO.

Use Value: V_CEsat ≤ 0.7 V ensures <250 mW dissipation at full brightness, eliminating need for heatsinking on FR4.

Use Scenario: Driving 24V coil of industrial relay with 80 mA hold current.

IC Role / Device Role / Timing Role: Low-side driver stage translating 3.3V logic to 24V load switching.

Use Value: h_FE ≥ 160 allows direct MCU GPIO drive without external base resistor scaling.

Consumer Audio Preamp Stage

Medical Sensor Signal Conditioning

Use Scenario: Class-A common-emitter amplifier for electret microphone output buffering.

IC Role / Device Role / Timing Role: Linear amplification with fixed bias point and local feedback.

Use Value: f_T = 200 MHz provides >10× bandwidth margin over 20 kHz audio band, minimizing phase distortion.

Use Scenario: Low-noise current mirror in analog front-end for photodiode signal extraction.

IC Role / Device Role / Timing Role: Precision current source with matched h_FE tracking across temperature.

Use Value: Tight h_FE binning (grp. 25) reduces gain mismatch to <±8% over −25°C to +85°C.

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 (ON Semiconductor)	Same h_FE range (160–250), but SOT23-3 package with different lead frame; R_thJS = 200 K/W	Compatible in layout but requires land pattern verification due to variant mold compound shrinkage	Select if sourcing from ON Semi distribution channels or requiring alternate logistics path
MMBT3906 (Central Semiconductor)	Lower h_FE (100–300, wider spread), V_CEO = 40 V, V_CEsat = 0.4 V (typ) at lower I_C	Less suitable for 500 mA loads due to higher V_CEsat drift above 300 mA	Prefer for cost-sensitive consumer designs where 300 mA max load suffices

Compared with BC807-25LT1G and MMBT3906, BC807-25 B5003 offers tighter h_FE consistency, higher V_CEO, and AEC-Q101 validation - making it optimal for automotive and industrial systems demanding predictable gain and thermal margin at 500 mA.

FAQ

What is the maximum continuous collector current for BC807-25 B5003?

The BC807-25 B5003 supports 500 mA continuous collector current (I_C) at T_S ≤ 79°C. At higher board temperatures, derating applies per the P_tot vs. T_S curve - e.g., 250 mA at T_S = 100°C. Peak pulsed current reaches 1000 mA with duty cycle <2% and pulse width <300 µs.

Is BC807-25 B5003 pin-compatible with BC817-25?

No - BC807-25 B5003 is PNP while BC817-25 is its NPN complementary counterpart. They share identical SOT23 pinout (1=Base, 2=Emitter, 3=Collector), but polarity reversal means direct substitution requires circuit topology changes, including bias network inversion and load relocation.

Does BC807-25 B5003 require a base resistor in switching applications?

Yes - a base resistor is required to limit I_B and ensure saturation. For 500 mA I_C, minimum I_B = I_C/h_FE(min) = 500 mA/160 ≈ 3.1 mA. With 3.3V GPIO driving V_BEsat ≈ 1.2 V, R_B ≈ (3.3 − 1.2)V / 3.1 mA ≈ 680 Ω. Lower values improve overdrive margin but increase MCU load.

What is the significance of the 'B5003' suffix in BC807-25 B5003?

The 'B5003' is Nexperia's internal manufacturing code indicating wafer lot, assembly site, and test revision. It does not affect electrical specifications or package dimensions. All BC807-25 devices - regardless of suffix - meet identical electrical, thermal, and qualification specs per datasheet Rev. 6 (2007-06-08).
