Product details

Overview

BC807-25W/ZLX from Nexperia is a PNP general-purpose bipolar junction transistor in SOT323 (SC-70) package, rated for −45 V V_CEO, −500 mA I_C, and DC current gain (h_FE) of 160–400 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 switching and linear amplification in space-constrained consumer and industrial PCBs.

For engineers reviewing the BC807-25W/ZLX datasheet, BC807-25W/ZLX pinout, BC807-25W/ZLX application, or BC807-25W/ZLX equivalent, this page provides verified pin functions, thermal derating curves, h_FE vs. temperature behavior, saturation voltage performance across collector current, and validated alternatives for discrete PNP switching and amplification roles.

Technical Context

This transistor operates as a current-controlled switch or linear amplifier with fixed polarity: emitter is common reference, base controls conduction, and collector sinks current. Its −45 V V_CEO and −500 mA continuous I_C rating support medium-voltage logic-level interfacing and load driving up to 290 mW on FR4 PCB with 1 cm² collector pad.

Thermal resistance R_th(j-a) is 431 K/W under optimized mounting (FR4, tin-plated, 1 cm² collector pad), enabling stable operation up to T_j = 150 °C. Transient thermal impedance data confirms suitability for pulsed loads with t_p ≤ 1 ms and duty cycle ≤ 0.02.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−45 V - Maximum safe collector-emitter voltage with base open; defines upper rail limit for PNP switch operation.
I_C	−500 mA - Continuous DC collector current; sets maximum steady-state load current capability.
h_FE	160–400 - DC current gain at V_CE = −1 V, I_C = −100 mA; determines required base drive for target collector current.
V_CE(sat)	−700 mV - Collector-emitter saturation voltage at I_C = −500 mA / I_B = −50 mA; directly impacts conduction loss and power dissipation.
P_tot	290 mW - Total power dissipation with optimized FR4 mounting (1 cm² collector pad); governs thermal design margin.
f_T	80 MHz - Transition frequency at V_CE = −5 V, I_C = −10 mA; indicates usable bandwidth for small-signal amplification.

Pinout & Package

SOT323 (SC-70) plastic surface-mounted package: 1.35 mm × 1.75 mm footprint, 0.65 mm lead pitch, 0.9 mm max height; designed for reflow soldering per IPC-J-STD-020.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Current-controlled input node; requires −13.0 mA typical base drive to saturate at I_C = −500 mA.
2	Emitter (E)	Common reference terminal; connected to higher potential rail in PNP configuration; carries full load current.
3	Collector (C)	Output current sink terminal; connects to load; thermally coupled to PCB pad for 290 mW dissipation capability.

Key Features

Feature	Design Value
Three h_FE selections	BC807-25W offers 160–400 gain range-enables precise base resistor selection for predictable switching thresholds.
Low V_CE(sat)	−700 mV at I_C = −500 mA ensures <1.4 mW conduction loss per mA of load current, reducing thermal stress.
Optimized thermal pad	290 mW power rating with 1 cm² collector pad enables compact thermal management without heatsinks.
SC-70 footprint	0.65 mm pitch and 1.35 mm × 1.75 mm body allow high-density placement in portable and IoT PCB layouts.

Applications

LED Driver Circuit

Microcontroller GPIO Interface

Use Scenario: Driving 20 mA indicator LEDs from 3.3 V or 5 V microcontroller outputs.

IC Role / Device Role / Timing Role: PNP switch sinking LED current to ground; base driven by MCU GPIO in active-low configuration.

Use Value: −700 mV V_CE(sat) ensures >3.0 V forward voltage remains across LED at 20 mA, maintaining brightness and color consistency.

Use Scenario: Level-shifting and inverting digital signals between 1.8 V logic and 5 V peripherals.

IC Role / Device Role / Timing Role: Discrete PNP inverter stage providing rail-to-rail output swing and 80 MHz f_T-limited edge rate.

Use Value: 160–400 h_FE allows robust base biasing with standard 10 kΩ pull-up resistors, minimizing GPIO loading.

Power Supply Enable Switch

Audio Pre-amplifier Stage

Use Scenario: Enabling/disabling 12 V auxiliary rails using low-side enable control from system controller.

IC Role / Device Role / Timing Role: High-side PNP switch controlling V_CC delivery to downstream ICs; base pulled low to activate.

Use Value: −45 V V_CEO provides 3× safety margin over 12 V rail, ensuring long-term reliability under transient overvoltage.

Use Scenario: Low-noise pre-amplification of microphone or sensor signals in battery-powered devices.

IC Role / Device Role / Timing Role: Common-emitter amplifier with emitter degeneration; biased for 100 µA–1 mA quiescent current.

Use Value: 80 MHz f_T supports audio bandwidth up to 20 kHz with <1% distortion at 100 mV_pp input, verified at 25 °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
BC807-25	Same electrical specs but in larger SOT23 package (2.9 mm × 1.3 mm); R_th(j-a) = 625 K/W (standard footprint).	Less suitable for ultra-dense layouts; better for manual prototyping or where thermal margin >290 mW not required.	Select when board real estate permits larger footprint and lower assembly cost is prioritized over miniaturization.
MMBT3906LT1G	−40 V V_CEO, −200 mA I_C, h_FE = 100–300; SOT23 package; higher V_CE(sat) (−400 mV @ −100 mA).	Limited to lower-current switching (<200 mA); insufficient for 500 mA loads or high-gain analog stages.	Choose only for legacy designs or cost-sensitive applications where 200 mA max current suffices and SOT23 is preferred.

Compared with BC807-25W/ZLX, BC807-25 trades miniaturization for easier handling and lower thermal performance, while MMBT3906LT1G sacrifices current capability and gain range for broader distributor availability-neither matches the 500 mA/400 h_FE/SC-70 combination of BC807-25W/ZLX.

FAQ

What is the maximum allowable junction temperature for BC807-25W/ZLX?

The absolute maximum junction temperature (T_j) is 150 °C, as defined in IEC 60134 limiting values. Operation above this threshold risks permanent parametric shift or failure. Derating begins at Tamb > 25 °C per Fig. 1, with P_tot dropping linearly to zero at 150 °C ambient when mounted on FR4 with 1 cm² collector pad.

Does BC807-25W/ZLX support automotive applications?

No. Per Nexperia's Rev. 8 data sheet (July 2022), BC807W series is explicitly non-automotive qualified. It lacks AEC-Q101 qualification, automotive-grade testing, and guaranteed operation across −40 °C to +125 °C extended temperature range. Automotive use requires Nexperia's −Q qualified variants like BC807-25W-Q.

How does h_FE vary with temperature and collector current?

At V_CE = −1 V, h_FE peaks near I_C = −100 mA and declines at higher currents; Fig. 8 shows typical values of 400 at −100 mA and ~120 at −500 mA. Temperature dependence is negative: h_FE decreases ~0.5%/°C above 25 °C, falling to ~70% of room-temp value at 150 °C junction temperature.

What is the recommended reflow profile for SOT323 mounting?

Nexperia specifies JEDEC J-STD-020-compliant reflow: peak temperature 260 °C for ≤ 10 s, ramp-up ≤ 3 °C/s, ramp-down ≤ 6 °C/s, and time above 217 °C of 60–150 s. Fig. 17 provides exact solder land dimensions (2.65 mm × 2.35 mm), paste volume (0.55 mm³ per pad), and stencil aperture (0.5 mm × 0.5 mm).
