Product details
Overview
BC807-40HZ from Nexperia is a PNP general-purpose bipolar junction transistor in SOT23 package, rated for −45 V VCEO, −500 mA continuous collector current, and DC current gain (hFE) of 250–600 at VCE = −1 V and IC = −100 mA. It operates reliably up to 175 °C junction temperature and is used in low-voltage switching and linear amplification circuits in industrial control modules.
For engineers reviewing the BC807-40HZ datasheet, BC807-40HZ pinout, BC807-40HZ application, or BC807-40HZ equivalent, this page delivers verified electrical parameters, thermal derating behavior, SOT23 terminal mapping, and validated alternatives for discrete PNP switching design.
Technical Context
This transistor implements standard PNP BJT architecture with base-emitter and collector-base junctions optimized for stable DC gain across wide temperature range (−55 °C to +175 °C). Its hFE binning (40H) ensures minimum 250 gain at IC = −100 mA, supporting predictable biasing in emitter-follower and common-emitter configurations.
Thermal performance is defined by four mounting-dependent Rth(j-a) values (280–470 K/W), reflecting power dissipation limits under varying PCB copper layer count and collector pad area - critical for sustained operation near 500 mA in compact industrial enclosures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −45 V: Maximum safe collector-emitter voltage with open base; defines off-state blocking capability in low-side switch applications. |
| IC | −500 mA: Continuous DC collector current at 25 °C ambient; sets maximum load drive capacity in relay drivers or LED sinks. |
| hFE | 250–600 @ VCE = −1 V, IC = −100 mA: Confirmed DC current gain range enabling precise base resistor calculation for saturation control. |
| VCE(sat) | ≤ −700 mV @ IC = −500 mA, IB = −50 mA: Verified saturation voltage ensuring ≤0.7 V drop during full-load conduction, minimizing power loss. |
| Tj(max) | +175 °C: Maximum junction temperature; supports operation in high-ambient environments like motor control housings or power supply heatsinks. |
| Ptot | 540 mW @ 4-layer FR4 PCB with 1 cm² collector pad: Real-world power handling limit under optimal thermal layout conditions. |
| fT | 80 MHz @ VCE = −5 V, IC = −10 mA: Transition frequency confirming suitability for audio-frequency amplification and <10 MHz switching. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package with 3 leads; standardized footprint per Nexperia's reflow and wave soldering guidelines (Fig. 44–45).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Current-controlled input node; requires series resistor to limit IB and ensure saturation at target IC. |
| 2 | Emitter (E) | Common reference terminal for PNP configuration; connected to higher potential rail in low-side switch topologies. |
| 3 | Collector (C) | Output current path; routed to load (e.g., relay coil or LED anode) with thermal pad connection recommended for >300 mA operation. |
Key Features
| Feature | Design Value |
|---|---|

| High-temperature operation | Rated for continuous operation up to +175 °C junction temperature, supporting use in sealed industrial enclosures without forced cooling. |
| Low VCE(sat) | ≤700 mV at full 500 mA load ensures <350 mW conduction loss, critical for thermally constrained PCB layouts. |
| Standard SOT23 footprint | Compatible with automated pick-and-place and reflow processes; matches JEDEC TO-236AB mechanical dimensions (3.0 × 1.4 × 1.1 mm). |
Applications
| Industrial Relay Driver | LED Current Sink |

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 |
|---|---|---|---|
| BC807-40W | Same hFE bin (250–600) but marked for wafer-level testing; identical electrical specs and SOT23 package. | No functional difference; W suffix denotes alternate test flow, not performance variation. | Select when sourcing from distributors emphasizing wafer-tested lots for traceability-critical programs. |
| MMBT3906LT1G | Lower VCEO (−40 V), lower hFE (100–300), and higher VCE(sat) (≤−800 mV @ −50 mA); same SOT23 footprint. | Not suitable for 45 V systems or high-gain biasing; acceptable only in ≤30 V, low-current (<100 mA) applications. | Choose only if cost sensitivity outweighs voltage margin and gain stability requirements. |
Compared with BC807-40HZ, BC807-40W offers identical performance with enhanced test documentation, while MMBT3906LT1G trades voltage headroom and gain consistency for broader distributor availability at lower cost in non-critical designs.

FAQ
What is the maximum allowable collector current for BC807-40HZ at 100 °C ambient temperature?
At Tamb = 100 °C, the maximum continuous collector current is derated to approximately −320 mA based on the 540 mW Ptot rating and thermal resistance of 280 K/W (4-layer PCB). This assumes proper heat spreading via the collector pad and no additional airflow.
Does BC807-40HZ support pulsed operation beyond its DC ratings?
Yes - peak collector current reaches −1 A for single pulses ≤1 ms (Tamb = 25 °C), as confirmed in Table 6. Safe operation requires adherence to the SOA curve (Fig. 2), especially limiting VCE during high-current pulses to avoid second breakdown.
How does the marking code "6U%" correspond to BC807-40HZ?
The marking "6U%" on the device body identifies the BC807-40HZ variant, where "6U" is the factory-specific code for the 40H gain bin, and "%" is a placeholder for the manufacturing site identifier per Table 5 - no functional impact on electrical behavior.
Can BC807-40HZ replace BC807-25H in an existing design without modification?
Yes - both share identical pinout, voltage/current ratings, and package. The higher hFE (250–600 vs. 160–400) may reduce required base drive, potentially improving noise immunity but requiring verification of base resistor value to avoid excessive IB in saturation.
