Product details
Overview
BC807-40W,115 from Nexperia is a PNP bipolar junction transistor (BJT) in SOT323 (SC-70) package, rated for −45 V VCEO, −500 mA IC, and DC current gain (hFE) of 250–600 at VCE = −1 V and IC = −100 mA. It serves as a general-purpose switching and amplification device in low-power analog and digital circuits, including level-shifting stages in portable power management and signal inversion in sensor interface boards.
For engineers reviewing the BC807-40W,115 datasheet, BC807-40W,115 pinout, BC807-40W,115 application, or BC807-40W,115 equivalent, key selection criteria include verified hFE range under pulsed conditions, thermal resistance (Rth(j-a) = 625 K/W on FR4), saturation voltage (VCE(sat) ≤ −700 mV at IC = −500 mA/IB = −50 mA), and SC-70 footprint compatibility with high-density PCB layouts.
Technical Context
This PNP transistor operates with open-base collector-emitter breakdown voltage of −45 V and emitter-base breakdown voltage of −5 V, supporting reliable operation in negative-rail biasing configurations. Its pulsed hFE test condition (tp ≤ 300 μs, duty δ ≤ 0.02) ensures stable gain behavior in switching applications with short conduction intervals.
Thermal performance is defined for two mounting conditions: standard FR4 footprint (Rth(j-a) = 625 K/W) and enhanced 1 cm² collector pad (Rth(j-a) = 431 K/W), enabling thermal design flexibility across consumer and industrial ambient ranges (−65 °C to +150 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −45 V - Maximum safe collector-emitter voltage with base open; defines rail-to-rail headroom in negative-supply switching. |
| IC | −500 mA - Continuous DC collector current rating; supports load switching up to 0.5 A in compact SMT designs. |
| hFE | 250–600 - Verified DC current gain at VCE = −1 V, IC = −100 mA, pulsed; enables predictable base drive sizing. |
| VCE(sat) | ≤ −700 mV - Collector-emitter saturation voltage at IC = −500 mA/IB = −50 mA; limits conduction loss in saturated switch mode. |
| Ptot | 200 mW - Total power dissipation on standard FR4 PCB; sets thermal derating boundary for ambient temperatures above 25 °C. |
| fT | 80 MHz - Transition frequency at VCE = −5 V, IC = −10 mA; confirms usable bandwidth for audio-frequency amplification and fast-switching control. |
| Cc | 5 pF - Collector capacitance at VCB = −10 V; impacts high-frequency response and Miller effect in amplifier stages. |
Pinout & Package
BC807-40W,115 uses the SOT323 (SC-70) surface-mount plastic package: 1.35 mm × 1.15 mm × 0.95 mm body, 0.65 mm lead pitch, and 3-terminal configuration optimized for automated placement and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control terminal for forward-biased PNP operation; requires negative base current relative to emitter to enable conduction. |
| 2 | Emitter (E) | Current source terminal; connected to higher potential (e.g., VCC or bias rail) in common-emitter switching configurations. |
| 3 | Collector (C) | Current sink terminal; delivers load current to ground or lower-potential node when transistor is saturated. |
Key Features
| Feature | Design Value |
|---|---|
| Three hFE variants | BC807-40W offers 250–600 hFE, enabling precise gain matching for consistent switching thresholds across production batches. |
| High peak current capability | 1 A ICM (single pulse, tp ≤ 1 ms) supports surge-tolerant operation in motor driver pre-driver or relay coil snubbing. |
| Low VBE | −1.2 V at IC = −500 mA enables efficient base drive with minimal voltage overhead in low-voltage systems. |
| Thermally robust SOT323 | 150 °C max junction temperature and −65 °C min storage temperature support extended operation in industrial environments. |
Applications
| LED Driver Stage | Level-Shifting Interface |
|---|---|
|
Use Scenario: Driving 20 mA indicator LEDs from 3.3 V microcontroller GPIO pins with inverted logic. IC Role / Device Role / Timing Role: PNP switch configured in common-emitter topology, sinking LED current to ground when base is pulled low. Use Value: VCE(sat) ≤ −700 mV ensures <150 mW dissipation per LED channel, minimizing self-heating in dense LED arrays. |
Use Scenario: Translating 5 V logic signals down to 3.3 V for interfacing legacy peripherals with modern MCUs. IC Role / Device Role / Timing Role: Active-low level shifter using emitter-follower configuration with base tied to 3.3 V reference. Use Value: hFE ≥ 250 guarantees sufficient current sourcing into 10 kΩ input loads without requiring external pull-up resistors. |
| Sensor Signal Inversion | Power Rail Sequencing |
|
Use Scenario: Inverting output of NPN-output ambient light sensor before feeding to ADC input of battery-powered IoT node. IC Role / Device Role / Timing Role: Single-transistor inverter stage providing rail-compatible swing and noise margin against supply ripple. Use Value: fT = 80 MHz ensures <10 ns propagation delay, preserving timing integrity for sub-100 kHz sensor sampling rates. |
Use Scenario: Enabling 12 V auxiliary rail only after main 5 V supply reaches regulation, using discrete power-good sequencing. IC Role / Device Role / Timing Role: High-side switch controlling gate of downstream PMOS FET via base resistor network. Use Value: −45 V VCEO provides 3× safety margin over 12 V rail, preventing breakdown during load-dump transients. |
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 | Same electrical specs but in larger SOT23 package (2.9 mm × 1.3 mm vs. SOT323's 1.35 mm × 1.15 mm); Rth(j-a) = 450 K/W on FR4. | Preferred where manual rework or thermal margin >625 K/W is required; unsuitable for ultra-dense layouts. | Select when board space allows larger footprint and thermal derating must exceed 200 mW at 70 °C ambient. |
| MMBT3906LT1G | −40 V VCEO, −200 mA IC, hFE = 100–300; SOT23 package; lower power handling and narrower gain range. | Used in low-current bias networks and low-speed logic; not suitable for 500 mA switching loads. | Choose only for signal-level inversion or biasing where IC < 150 mA and VCEO < −40 V suffices. |
Compared with BC807-40W,115, BC807-40,115 trades miniaturization for improved thermal performance and ease of handling, while MMBT3906LT1G sacrifices current capacity and gain consistency for cost-sensitive, low-power signal-chain roles.

FAQ
What is the maximum allowable base current for continuous operation?
The absolute maximum peak base current is −200 mA (single pulse, tp ≤ 1 ms), but continuous operation must limit IB to ensure IC ≤ −500 mA and Ptot ≤ 200 mW. At IC = −500 mA and hFE = 250, IB ≈ −2 mA; practical designs use 5–10× overdrive (−10 to −20 mA) for saturation, staying well within thermal limits on FR4.
Can BC807-40W,115 be used in linear amplifier configurations?
Yes - its fT = 80 MHz and hFE stability across IC = −1 mA to −500 mA support Class-A and Class-AB audio preamplifier stages. However, linearity is optimized at VCE ≥ −2 V; operation below −1 V increases distortion due to Early effect and reduced hFE.
Is this part qualified for automotive applications?
No - BC807-40W,115 is explicitly marked non-automotive qualified per Revision History v.8 (2022). It lacks AEC-Q101 stress testing and automotive-specific reliability reporting. For automotive use, Nexperia's BC807-40Q series (with "-Q" suffix) must be selected.
How does the SOT323 package affect soldering yield in high-volume assembly?
The SOT323 footprint (0.65 mm pitch, 0.5 mm pad width) is compatible with standard Type 3 solder paste and 0201-class stencil apertures. Reflow profiles must maintain peak temperature ≤ 260 °C for ≤ 10 s; wave soldering requires the recommended 3.65 mm × 2.1 mm footprint (Fig. 18) to prevent tombstoning and ensure coplanar wetting of all three terminals.
