Product details

Overview

BC807-25W/ZLF from Nexperia is a PNP 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 160–400 at V_CE = −1 V and I_C = −100 mA. It serves as a general-purpose switching and amplification device in low-power analog and digital interface circuits, including level-shifting stages in microcontroller I/O drivers.

For engineers reviewing the BC807-25W/ZLF datasheet, BC807-25W/ZLF pinout, BC807-25W/ZLF application, or BC807-25W/ZLF equivalent, key selection criteria include verified h_FE binning (160–400), thermal resistance (R_th(j-a) = 625 K/W on FR4), saturation voltage (V_CEsat ≤ −700 mV at I_C = −500 mA / I_B = −50 mA), and SC-70 footprint compatibility with high-density PCB layouts.

Technical Context

This PNP transistor operates with open-base collector-emitter breakdown of −45 V and emitter-base breakdown of −5 V, supporting reliable operation in negative-rail biasing configurations. Its pulsed peak collector current rating is −1 A (t_p ≤ 1 ms), enabling short-duration surge handling in power control nodes.

Thermal performance is defined for two mounting conditions: standard FR4 footprint (R_th(j-a) = 625 K/W) and enhanced 1 cm² collector pad (R_th(j-a) = 431 K/W). Transition frequency f_T is 80 MHz at V_CE = −5 V, I_C = −10 mA, confirming suitability for low-frequency signal amplification and switching up to ~10 MHz.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−45 V - Maximum safe collector-emitter voltage with base open; defines rail-to-rail headroom in PNP switch applications.
I_C	−500 mA - Continuous DC collector current; supports load switching up to ~500 mA in compact SOT323 form factor.
h_FE	160–400 - Guaranteed DC current gain range at V_CE = −1 V, I_C = −100 mA; enables predictable base drive sizing.
V_CEsat	≤ −700 mV - Collector-emitter saturation voltage at I_C = −500 mA / I_B = −50 mA; ensures low conduction loss in saturated switch mode.
f_T	80 MHz - Transition frequency at V_CE = −5 V, I_C = −10 mA; confirms usable bandwidth for audio and low-speed digital signal buffering.
R_th(j-a)	625 K/W - Junction-to-ambient thermal resistance on standard FR4 PCB; determines temperature rise under continuous 300 mW dissipation.

Pinout & Package

BC807-25W/ZLF uses the SOT323 (SC-70) surface-mount plastic package - a 3-lead, ultra-small outline measuring 2.2 mm × 1.35 mm × 0.95 mm (L × W × H) with 0.65 mm lead pitch. The package is optimized for reflow soldering and high-density placement.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Control terminal; requires current-limited drive (e.g., series resistor) to achieve target I_C based on h_FE bin.
2	Emitter (E)	Common reference node; connected to higher potential rail in PNP switch configuration (e.g., +V_CC).
3	Collector (C)	Output terminal; sinks current from load to ground or lower-potential node when B is pulled low relative to E.

Key Features

Feature	Design Value
Three h_FE bins	BC807-25W offers 160–400 h_FE, enabling precise base drive design without overdesigning current-limiting resistors.
High-voltage PNP capability	−45 V V_CEO allows use in 24 V industrial control rails and −36 V telecom bias networks without derating.
Low V_CEsat	≤ −700 mV at full rated current minimizes power loss and self-heating in always-on or PWM-driven loads.
SOT323 footprint	Standardized SC-70 land pattern (2.65 mm × 2.35 mm solder mask opening) ensures compatibility with automated assembly lines.

Applications

Industrial Sensor Interface

Microcontroller Level Shifting

Use Scenario: Amplifying weak NTC thermistor signals in 24 V-powered HVAC controllers with rail-referenced ADC inputs.

IC Role / Device Role / Timing Role: PNP amplifier stage providing inverted, buffered output with gain stability across −40 °C to +85 °C ambient.

Use Value: 160–400 h_FE bin ensures consistent transconductance; −45 V rating accommodates transient spikes on 24 V supply lines.

Use Scenario: Converting 3.3 V logic outputs from an ARM Cortex-M0+ MCU to drive 5 V/12 V relay coils or optocouplers.

IC Role / Device Role / Timing Role: Active-low switch sinking up to 500 mA, with fast turn-off enabled by low C_c (5 pF) and 80 MHz f_T.

Use Value: V_CEsat ≤ −700 mV limits coil driver loss to <150 mW; SOT323 size saves board space in multi-channel IO expanders.

LED Driver for Status Indication

Power Supply Enable Control

Use Scenario: Driving multiple parallel red/green LEDs (20 mA each) from a shared 5 V rail in network equipment front panels.

IC Role / Device Role / Timing Role: Low-side PNP current sink configured in common-emitter mode with fixed base bias.

Use Value: Guaranteed h_FE range allows single-resistor base drive design; R_th(j-a) = 625 K/W permits continuous operation at 70 °C ambient.

Use Scenario: Enabling/disabling a 3.3 V LDO regulator via its EN pin using a 1.8 V FPGA GPIO in battery-powered IoT nodes.

IC Role / Device Role / Timing Role: Voltage-level translator and current amplifier, pulling EN high through emitter-follower configuration.

Use Value: −5 V V_EBO rating safely handles reverse-biased base-emitter junction during 1.8 V → 3.3 V translation.

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	Same h_FE bin (160–400), identical SOT-23 package but larger footprint (2.9 mm × 1.3 mm vs. SOT323's 2.2 mm × 1.35 mm); R_th(j-a) = 400 K/W (enhanced thermal pad).	Preferred where thermal margin > electrical specs; unsuitable for ultra-dense layouts requiring SC-70 size.	Select when board layout allows larger SOT-23 and junction temperature must stay <110 °C at 400 mW dissipation.
MMBT3906LT1G	Lower V_CEO (−40 V), narrower h_FE range (100–300), same SOT-23 package; f_T = 250 MHz.	Better for high-speed switching (>10 MHz) but less robust in 24 V industrial transients.	Choose only if speed is critical and supply rails are tightly regulated below 36 V; avoid in unfiltered 24 V systems.

Compared with BC807-25W/ZLF, BC807-25LT1G trades miniaturization for thermal headroom, while MMBT3906LT1G sacrifices voltage margin and gain consistency for higher bandwidth - making BC807-25W/ZLF optimal for space-constrained, medium-voltage industrial interfaces.

FAQ

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

The absolute maximum junction temperature (T_j) is 150 °C, as specified in the Limiting Values table. Operation above this threshold risks permanent parametric shift or failure. Derating is required above 25 °C ambient: total power dissipation must be reduced linearly to zero at 150 °C, based on R_th(j-a) = 625 K/W for standard FR4 mounting.

Does BC807-25W/ZLF support automotive applications?

No - BC807-25W/ZLF is explicitly marked as non-automotive qualified in the revision history (Rev. 8, July 2022). It lacks AEC-Q101 qualification, automotive-grade screening, and guaranteed operation across −40 °C to +125 °C. For automotive use, Nexperia offers the BC807-25Q series with full AEC-Q101 compliance and extended temperature validation.

How does the marking code '5B%' identify BC807-25W/ZLF on the package?

The top-side marking '5B%' indicates BC807-25W, where '5B' is the device-specific code per Table 5, and '%' is a placeholder for the manufacturing site identifier (e.g., 'A' for Nijmegen, 'B' for Bangkok). This matches Nexperia's standard SOT323 marking convention and distinguishes it from BC807-16W ('5A%') and BC807-40W ('5C%').

Can BC807-25W/ZLF replace BC807-16W in an existing design?

Yes, with verification - both share identical package, pinout, and voltage/current ratings, but BC807-25W has higher minimum h_FE (160 vs. 100). This may reduce required base drive current, potentially improving noise immunity. However, check circuit stability under worst-case h_FE = 400, especially in linear amplifier configurations where gain variation affects bias point.
