Product details

Overview

BC807-40W H6433 from Nexperia is a PNP silicon general-purpose audio-frequency transistor in SOT323 package, rated for 45 V V_CEO, 500 mA I_C, and 250 mW power dissipation at T_S ≤ 130 °C, with h_FE = 250–630 (IC = 100 mA, V_CE = 1 V), V_CE(sat) ≤ 0.7 V (IC = 500 mA, IB = 50 mA), and f_T = 200 MHz - used in low-voltage switching and linear amplification stages of automotive body control modules.

For engineers reviewing the BC807-40W H6433 datasheet, BC807-40W H6433 pinout, BC807-40W H6433 application, or BC807-40W H6433 equivalent, key selection criteria include guaranteed h_FE group 40 performance across temperature, RoHS-compliant SOT323 thermal resistance (R_thJS ≤ 80 K/W), and AEC-Q101 qualification for automotive-grade reliability.

Technical Context

This PNP bipolar junction transistor operates in active, saturation, and cutoff regions with DC current gain specified across three h_FE groups (16/25/40); BC807-40W delivers minimum h_FE = 250 at IC = 100 mA and V_CE = 1 V, rising to 400–630 at lower currents. Its low V_CE(sat) and V_BE(sat) support efficient switching in 5–12 V rail systems.

Thermal design is enabled by SOT323 package-specific R_thJS ≤ 80 K/W and derated P_tot = 250 mW above 130 °C case temperature. AC performance includes f_T = 200 MHz and C_cb = 8 pF (VCB = 10 V), suitable for AF and low-speed digital signal conditioning.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	45 V - supports operation in 24 V automotive supply rails with margin against transients
I_C	500 mA continuous - drives medium-power loads like relays, LEDs, and small solenoids
h_FE (min)	250 @ IC = 100 mA - ensures stable biasing in emitter-follower and switch driver configurations
V_CE(sat)	≤ 0.7 V @ IC = 500 mA, IB = 50 mA - minimizes conduction loss and self-heating in saturated switching
f_T	200 MHz - enables use in audio preamplifiers and low-frequency pulse shaping circuits
R_thJS	≤ 80 K/W - allows direct PCB copper pour thermal coupling for improved power handling in compact layouts
AEC-Q101	Qualified - meets stress test requirements for automotive electronics including temperature cycling and HTSL

Pinout & Package

BC807-40W H6433 is housed in a RoHS-compliant SOT323 plastic surface-mount package with standard lead finish and moisture sensitivity level (MSL) 1.

Pin/Terminal	Circuit Role	Design Meaning
1 (Base)	Control input	Receives base current to regulate collector-emitter conduction; requires current-limiting resistor in series
2 (Emitter)	Current source reference	Connected to higher potential rail in PNP configuration; provides return path for load current
3 (Collector)	Output terminal	Delivers controlled current to load; polarity reversed vs NPN - sinks current when active

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive under-hood applications including BCM, lighting, and HVAC actuators
h_FE group 40	Guaranteed minimum DC current gain of 250 ensures consistent switching thresholds across production lots
SOT323 thermal resistance	R_thJS ≤ 80 K/W enables 250 mW dissipation at 130 °C case temperature without heatsink
Low V_CE(sat)	≤ 0.7 V reduces power loss and improves efficiency in high-duty-cycle switching applications
Complementary NPN pairing	Direct match with BC817-40W/BC818-40W for push-pull output stages and differential amplifiers

Applications

Automotive Body Control Module

Industrial Sensor Interface

Use Scenario: Driving 12 V relay coils and LED status indicators in door module PCBs.

IC Role / Device Role / Timing Role: PNP switch controlling load current sourced from battery rail.

Use Value: Low V_CE(sat) and guaranteed h_FE ensure reliable coil actuation even at cold cranking voltages (6.5 V).

Use Scenario: Level-shifting and buffering analog sensor outputs (e.g., thermistor networks) into microcontroller ADC inputs.

IC Role / Device Role / Timing Role: Emitter-follower buffer providing low-output-impedance drive without inversion.

Use Value: High h_FE and low C_eb preserve signal fidelity up to 20 kHz while isolating sensitive analog nodes.

Consumer Audio Preamp Stage

Power Supply Enable Circuit

Use Scenario: First-stage voltage amplification in portable speaker amplifier input stage.

IC Role / Device Role / Timing Role: Common-emitter amplifier with fixed bias network and emitter degeneration.

Use Value: f_T = 200 MHz and low noise characteristics support clean gain up to 20 kHz with minimal distortion.

Use Scenario: Enabling/disabling secondary 5 V LDO regulator based on system sleep/wake command.

IC Role / Device Role / Timing Role: High-side switch controlling EN pin of downstream regulator.

Use Value: Fast turn-off (limited by C_cb/C_eb) and low leakage (<100 nA IEBO) prevent unintended regulator activation during standby.

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
BC807-40 SOT23	Same die, but in larger SOT23 package with R_thJS ≤ 215 K/W and P_tot = 330 mW at T_S ≤ 79 °C	Lower power density; suited for non-automotive, board-space-tolerant designs with passive cooling	Select when thermal budget permits larger footprint and higher ambient operating temperature is not required
ZTX653 SOT23	Higher V_CEO = 60 V, h_FE = 200–450, but not AEC-Q101 qualified; R_thJS ≈ 120 K/W	Not automotive-qualified; better for industrial power supplies needing extended voltage margin	Choose only for non-automotive applications requiring >45 V breakdown or tighter h_FE tolerance

Compared with BC807-40W H6433, the SOT23 variant offers higher absolute power handling but poorer thermal performance per unit area, while ZTX653 trades automotive qualification for wider voltage range - making BC807-40W optimal for space-constrained, thermally managed automotive modules.

FAQ

What is the maximum operating junction temperature for BC807-40W H6433?

The absolute maximum junction temperature (T_j) is 150 °C, as specified in the Absolute Maximum Ratings table. Operation beyond this limit risks permanent device degradation. Thermal design must ensure T_j remains within specification using the provided R_thJS ≤ 80 K/W and derated power curves.

Is BC807-40W H6433 pin-compatible with BC807-40?

Yes - both share identical pinout (1=Base, 2=Emitter, 3=Collector) and electrical specifications, differing only in package (SOT323 vs SOT23) and thermal ratings. PCB layout must accommodate SOT323 footprint, and thermal management must reflect the lower R_thJS and different P_tot derating curve.

Does BC807-40W H6433 support pulsed operation?

Yes - permissible pulse load data shows P_tot(max)/P_tot(DC) ratios up to 10× for pulse widths <100 µs (duty cycle D ≤ 0.005). This enables short-duration surge current handling beyond 500 mA, provided average power stays within 250 mW limits and thermal mass prevents junction overheating.

How does h_FE vary with temperature for BC807-40W H6433?

h_FE decreases with rising temperature: typical values drop ~25% from 25 °C to 105 °C at IC = 100 mA. The datasheet provides h_FE vs IC curves across –40 °C to +105 °C, confirming minimum 250 remains valid over full automotive ambient range when operated within rated conditions.
