Product details
Overview
NSVBCH807-40LT1G from onsemi is a PNP silicon general-purpose transistor rated for −45 V VCEO, −500 mA IC continuous, and 175 °C maximum junction temperature, optimized for automotive load switching and high-reliability industrial control circuits.
For engineers reviewing the NSVBCH807-40LT1G datasheet, pinout, applications, or equivalent options, key selection criteria include DC current gain (hFE = 250–600 at IC = −500 mA), low VCE(sat) (≤ −0.7 V), AEC-Q101 qualification, and SOT-23 package thermal performance on FR-4 and alumina substrates.
Technical Context
This device operates as a medium-power PNP bipolar junction transistor with fixed emitter-base and collector-base breakdown limits (V(BR)EBO = −5.0 V, V(BR)CBO = −50 V) and specified saturation behavior under IC/IB = 10 drive conditions. Its fT of 100 MHz supports moderate-speed switching up to ~100 kHz in linear or saturated operation.
Thermal design is constrained by RJA = 400 °C/W on FR-4 (1 oz Cu, 100 mm²) and 330 °C/W on alumina substrate, with derating slopes of 1.3 mW/°C and 1.8 mW/°C respectively. Junction-to-storage temperature range spans −55 °C to +175 °C, enabling deployment in under-hood automotive environments.
Key Specifications

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 |
|---|---|---|---|
| NSVBCH807-25LT1G | Lower hFE range (160–400), same VCEO/IC/package | Suitable where reduced gain suffices and tighter hFE tolerance is acceptable | Select when base drive margin is ample and cost optimization is prioritized |
| BC807-40W | Same electrical specs but SOT-323 package (smaller footprint, higher RJA ≈ 450 °C/W) | Preferred for space-constrained boards where thermal budget allows higher junction rise | Choose only if board area savings outweigh thermal derating impact |
Compared with NSVBCH807-40LT1G, the NSVBCH807-25LT1G offers lower gain at identical voltage/current ratings, while BC807-40W trades thermal performance for smaller size-neither is pin-compatible due to differing SOT-23 vs. SOT-323 footprints, requiring layout revision.

FAQ
What is the maximum junction temperature rating for NSVBCH807-40LT1G?
The NSVBCH807-40LT1G has a maximum junction temperature (TJ) rating of +175 °C, validated per AEC-Q101 stress testing. This allows uninterrupted operation in under-hood automotive environments and sealed industrial enclosures without forced cooling. The NSVBCH807-40LT1G maintains specified electrical parameters across its full −55 °C to +175 °C operating range.
Is NSVBCH807-40LT1G pin-compatible with standard BC807-40 variants?
No-NSVBCH807-40LT1G uses the SOT-23 (case 318, style 6) package with pin 1 = Base, pin 2 = Emitter, pin 3 = Collector, matching BC807-40 pinout. However, the NSV prefix denotes automotive-specific process controls and traceability; it is not a mechanical or electrical drop-in for non-NSV parts unless explicitly qualified for the target application.
What does the "NSV" prefix signify in NSVBCH807-40LT1G?
The "NSV" prefix in NSVBCH807-40LT1G identifies a dedicated automotive-grade manufacturing flow with enhanced process controls, lot-level traceability, and PPAP documentation support. It confirms AEC-Q101 qualification and distinguishes the part from commercial-grade BCH807-40LT1G variants, ensuring compliance with automotive quality and reliability requirements.
What is the typical DC current gain (hFE) of NSVBCH807-40LT1G at rated current?
The NSVBCH807-40LT1G exhibits hFE = 250–600 at IC = −500 mA and VCE = −1.0 V, per the datasheet's Electrical Characteristics table. This wide gain range reflects process variation but ensures sufficient drive margin for saturated switching applications. Designers should verify base resistor values using the minimum hFE (250) to guarantee turn-on under worst-case conditions.
Does NSVBCH807-40LT1G support high-frequency switching applications?
The NSVBCH807-40LT1G has an fT of 100 MHz, indicating usable small-signal amplification up to that frequency. However, as a general-purpose PNP transistor, it is optimized for switching speeds up to ~100 kHz in saturated mode. For faster switching, designers must account for storage time and use appropriate base drive (e.g., Baker clamp or active pull-down) to minimize turn-off delay in the NSVBCH807-40LT1G.
