Product details

Overview

BC807-40W/ZLX from Nexperia is a PNP general-purpose bipolar junction transistor (BJT) in SOT323 (SC-70) package, rated for −45 V V_CEO, −500 mA I_C, and DC current gain (h_FE) of 250–600 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 high-speed switching up to 80 MHz f_T, commonly used in low-voltage power management and signal-level amplification stages.

For engineers reviewing the BC807-40W/ZLX datasheet, BC807-40W/ZLX pinout, BC807-40W/ZLX application, or BC807-40W/ZLX equivalent, key selection criteria include guaranteed h_FE range, thermal resistance (R_th(j-a) = 431 K/W with 1 cm² collector pad), SOT323 footprint compatibility, and −5 V V_EBO for base-emitter reverse bias tolerance in logic interface circuits.

Technical Context

This PNP BJT operates as a current-controlled switch or linear amplifier with fixed polarity and no integrated biasing or protection. Its h_FE spread (250–600) enables predictable gain staging in multi-transistor configurations, while its −45 V V_CEO and −50 V V_CBO support operation in 24 V and 36 V industrial supply rails. The device uses silicon planar epitaxial construction and is qualified per JEDEC JESD22 standards.

Thermal performance is defined for two mounting conditions: standard FR4 PCB (R_th(j-a) = 625 K/W) and enhanced 1 cm² collector pad layout (R_th(j-a) = 431 K/W). Transient thermal impedance curves confirm stable pulse handling up to 1 ms at 200 mA peak base current, supporting PWM-driven load control.

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 24 V/36 V systems.
I_C	−500 mA - Continuous DC collector current; supports medium-power switching loads like relays and LED strings.
h_FE	250–600 at V_CE = −1 V, I_C = −100 mA - Guaranteed DC current gain range ensures consistent base drive sizing across production lots.
V_CE(sat)	−700 mV at I_C = −500 mA, I_B = −50 mA - Low saturation voltage minimizes conduction loss in high-current switching applications.
f_T	80 MHz - Transition frequency enables reliable operation in audio preamplifiers and low-MHz digital signal buffering.
C_c	5 pF - Collector capacitance limits high-frequency Miller effect; suitable for <10 MHz switching without added compensation.
R_th(j-a)	431 K/W with 1 cm² collector pad - Thermal resistance enables 290 mW power dissipation at 25 °C ambient in optimized layout.

Pinout & Package

SOT323 (SC-70) plastic surface-mounted package: 1.35 mm × 1.75 mm footprint, 0.65 mm pitch, 0.9 mm height, 3-terminal configuration with gull-wing leads.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Current-controlled input node; requires series resistor to limit I_B ≤ −200 mA peak to avoid damage.
2	Emitter (E)	Common reference terminal for PNP topology; connected to higher potential rail in switching configurations.
3	Collector (C)	Output current path; thermally coupled to PCB pad in layout-critical for achieving 431 K/W R_th(j-a).

Key Features

Feature	Design Value
Three h_FE variants	BC807-16W (100–250), BC807-25W (160–400), BC807-40W (250–600) - Enables precise gain matching without external feedback networks.
Low V_CE(sat)	−700 mV at I_C/I_B = 10 - Reduces power loss in saturated switching, improving efficiency in battery-powered regulators.
High f_T	80 MHz - Supports clean amplification of audio-band signals and fast edge response in digital level-shifting circuits.
Robust thermal design	150 °C max junction temperature with validated derating curves - Ensures reliability in enclosed industrial enclosures up to 75 °C ambient.
Standard SC-70 footprint	Compatible with JEDEC MO-203-AB and IPC-7351A LCC1350X1750X400N - Enables drop-in replacement and automated assembly on legacy SMT lines.

IC Role / Device Role / Timing Role: High-current saturated switch controlled by microcontroller GPIO via base resistor.

Use Value: −700 mV V_CE(sat) limits conduction loss to <250 mW; 1 A I_CM supports PWM dimming with 100 ns turn-off time.

Logic-Level Translation

Power Supply Enable Switch

Use Scenario: Converting 3.3 V CMOS logic outputs to −5 V control signals for analog multiplexers in mixed-signal test equipment.

IC Role / Device Role / Timing Role: Inverting level shifter with pull-up to negative rail and grounded emitter.

Use Value: 80 MHz f_T ensures sub-10 ns propagation delay; −5 V V_EBO tolerates full logic swing without clamping diodes.

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
BC807-40,115 (Nexperia)	Same electrical specs but in larger SOT23 package (2.9 mm × 1.3 mm); R_th(j-a) = 380 K/W with 1 cm² pad.	Preferred where board space allows and higher thermal margin is needed; not foot-print compatible with SOT323.	Select when thermal budget is tight and rework of land pattern is acceptable.
MMBT3906LT1G (onsemi)	Lower h_FE range (100–300); identical SOT323 footprint; V_CEO = −40 V; f_T = 250 MHz.	Better for RF-coupled switching above 20 MHz but less suitable for precision DC gain applications requiring >250 h_FE.	Choose for high-frequency digital switching where gain consistency is secondary to speed.

Compared with BC807-40W/ZLX, BC807-40,115 offers superior thermal performance in larger footprint, while MMBT3906LT1G trades guaranteed high h_FE for higher f_T-making BC807-40W/ZLX optimal for stable gain-critical analog and medium-speed power control.

FAQ

What is the maximum allowable base current for continuous operation?

The absolute maximum peak base current is −200 mA for single pulses ≤1 ms, but continuous DC base current must be limited to ensure I_C ≤ −500 mA and junction temperature stays below 150 °C. At 25 °C ambient with 1 cm² copper pad, sustained I_B should not exceed −50 mA to maintain safe thermal margin under worst-case h_FE (250).

Does BC807-40W/ZLX support automotive applications?

No. This variant is explicitly non-automotive qualified per Nexperia's revision history (v.8, July 2022), which states the BC807W_SER series changed to non-automotive qualification. Automotive alternatives-such as BC807-40Q-require separate qualification per AEC-Q101 and are marked with "Q" suffix.

How does the marking code "5C%" correlate to the part number?

"5C%" is the top-side laser marking for BC807-40W, where "5C" identifies the h_FE group (250–600), and "%" is a placeholder for the manufacturing site code (e.g., "A" for Nijmegen, "B" for Bangkok). This matches Table 5 in the official datasheet and is verified on Digi-Key and Mouser packaging labels.

Can BC807-40W/ZLX replace BC807-25W in existing designs?

Yes, with verification: both share identical package, pinout, and voltage/current ratings, but BC807-40W has higher minimum h_FE (250 vs. 160). This may reduce required base drive in saturated switching, but could affect stability in linear amplifier configurations relying on tighter gain tolerance-re-simulation of bias points is recommended.
