onsemi NSVBCW68GLT1G

Overview

NSVBCW68GLT1G from onsemi is a PNP silicon general-purpose transistor rated for −45 V_CEO, −800 mA continuous collector current, and 100 MHz f_T, housed in an SOT-23 package. It delivers DC current gain (h_FE) of 120–400 at −10 to −300 mA, with V_CE(sat) ≤ −0.7 V at −500 mA/−50 mA drive, suitable for automotive load switching and industrial signal amplification.

For engineers reviewing the NSVBCW68GLT1G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q101 qualification, −55 °C to +150 °C operating range, SOT-23 thermal resistance of 417 °C/W on alumina substrate, and verified PNP switching performance under high-temperature bias conditions.

Technical Context

This device operates as a medium-power PNP bipolar junction transistor with fixed-emitter configuration and base-controlled conduction. Its design supports linear amplification and saturated switching in low-voltage DC circuits, with guaranteed V_(BR)CEO = −45 V and V_BE(sat) ≤ −2.0 V at −500 mA/−50 mA.

Thermal performance is defined for two board types: FR-5 (225 mW @ 25 °C, 1.8 mW/°C derating) and alumina substrate (300 mW @ 25 °C, 2.4 mW/°C derating), enabling use in thermally constrained automotive modules and industrial control PCBs.

FAQ

What is the maximum collector-emitter voltage rating for NSVBCW68GLT1G?

The NSVBCW68GLT1G has a maximum collector-emitter voltage (V_CEO) rating of −45 Vdc, tested under specified conditions with I_C = −10 mA and I_B = 0. This rating ensures safe operation in 12 V and 24 V automotive systems subject to load-dump transients up to ISO 7637-2 Pulse 5a. Exceeding this voltage may cause irreversible breakdown of the NSVBCW68GLT1G.

Is NSVBCW68GLT1G suitable for high-temperature industrial applications?

Yes, the NSVBCW68GLT1G is rated for junction temperatures from −55 °C to +150 °C and is AEC-Q101 qualified, making it suitable for under-hood automotive and industrial environments such as motor drives and power supplies. Its thermal resistance of 417 °C/W on alumina substrate allows reliable operation at full −800 mA load current up to +125 °C ambient when properly heatsinked.

What does the "NSV" prefix indicate on NSVBCW68GLT1G?

The "NSV" prefix on NSVBCW68GLT1G identifies it as a version manufactured under onsemi's automotive-specific quality system, with unique site and process control change requirements, full PPAP documentation support, and traceability aligned to IATF 16949. It distinguishes the NSVBCW68GLT1G from commercial-grade variants like BCW68GLT1G and confirms its eligibility for automotive production programs.

Does NSVBCW68GLT1G have a documented pinout compatible with standard SOT-23 footprints?

Yes, the NSVBCW68GLT1G uses Style 6 pinout per onsemi's mechanical drawings: pin 1 = BASE, pin 2 = EMITTER, pin 3 = COLLECTOR. This matches JEDEC TO-236 standard orientation and is compatible with standard SOT-23 land patterns (1.90 mm pitch). The NSVBCW68GLT1G footprint requires no layout revision when replacing other Style 6 SOT-23 PNP transistors.

What is the typical current-gain-bandwidth product (f_T) of NSVBCW68GLT1G?

The NSVBCW68GLT1G has a minimum current-gain-bandwidth product (f_T) of 100 MHz, measured at I_C = −20 mA, V_CE = −10 Vdc, and f = 100 MHz. This enables use in audio-frequency amplifiers and low-speed digital switching applications up to ~10 MHz, though actual usable bandwidth depends on bias point and external impedance matching in the NSVBCW68GLT1G circuit implementation.
