onsemi NSVMSB92T1G

Overview

NSVMSB92T1G from onsemi is a PNP silicon planar transistor designed for high-voltage general-purpose amplifier applications, featuring −300 V collector-emitter and collector-base breakdown voltages, 150 mA continuous collector current, 150 mW power dissipation, and 50 MHz transition frequency - deployed in industrial voltage amplification stages requiring robust off-state blocking.

For engineers reviewing the NSVMSB92T1G datasheet, pinout, applications, or equivalent options, key selection criteria include high-voltage PNP switching capability, SC−59 surface-mount compatibility, DC current gain across temperature (25–100 at IC = −10 mA), saturation voltage under defined drive conditions, and thermal performance up to 150°C junction temperature.

Technical Context

This device operates as a medium-power PNP bipolar junction transistor with fixed polarity and non-reconfigurable terminal roles. Its high −300 V V(BR)CEO and V(BR)CBO ratings enable use in flyback snubber circuits and HV bias networks where reverse-blocking integrity is critical.

The SC−59 package supports low-profile PCB mounting with validated thermal resistance (from junction-to-ambient under FR-4 conditions), while fT = 50 MHz and Ccb ≤ 6.0 pF indicate suitability for audio-frequency amplification and moderate-speed switching below 10 MHz.

Key Specifications

Pinout & Package

The NSVMSB92T1G is housed in the SC−59 (Case 318D, Style 1) surface-mount package - a 3-pin, low-profile plastic package measuring 2.90 × 1.50 × 1.15 mm with 1.90 mm lead pitch, optimized for automated assembly and thermal performance on FR-4 boards.

Key Features

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP high-voltage transistor applications.

Compared with MMDT3906-7-F and ZTX653, the NSVMSB92T1G uniquely balances −300 V blocking, SC−59 surface-mount compatibility, and 150 mW FR-4-limited dissipation - making it optimal for compact, medium-voltage SMT amplifier and snubber designs where leaded alternatives or low-voltage devices fall short.

FAQ

What is the maximum collector-emitter voltage rating for NSVMSB92T1G?

The NSVMSB92T1G has a guaranteed minimum collector-emitter breakdown voltage V(BR)CEO of −300 V at IC = −1.0 mA and IB = 0. This rating is validated per onsemi's datasheet Rev. 2 (January 2025) and defines the maximum reverse bias the device can sustain before avalanche conduction begins. Operation beyond this voltage risks irreversible junction damage, even for short durations.

Is NSVMSB92T1G compatible with lead-free reflow soldering processes?

Yes, the NSVMSB92T1G is a Pb-free device compliant with JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for standard reflow profiles. Its SC−59 package uses lead-free terminations and molding compound, supporting peak reflow temperatures up to 260°C. The device marking includes "G" or microdot to indicate Pb-free status per onsemi's generic marking diagram.

What is the DC current gain (hFE) range of NSVMSB92T1G at different operating points?

The NSVMSB92T1G exhibits hFE1 ≥ 25 at VCE = −10 V and IC = −1.0 mA, hFE2 ≥ 40 at VCE = −10 V and IC = −10 mA, and hFE3 ≥ 25 at VCE = −10 V and IC = −30 mA. These values are specified at TA = 25°C and reflect typical gain behavior across its linear operating region - critical for designing stable bias networks in amplifier or switch applications using the NSVMSB92T1G.

Can NSVMSB92T1G be used in automotive under-hood applications?

The NSVMSB92T1G is rated for junction temperatures up to +150°C and storage from −55°C to +150°C, meeting baseline thermal requirements for under-hood environments. However, it is not AEC-Q101 qualified. For automotive production use, NSVMSB92T1G must undergo customer-specific qualification testing; its electrical parameters and reliability data are derived from commercial-grade characterization, not automotive stress protocols.

What is the pin configuration of NSVMSB92T1G in the SC−59 package?

The NSVMSB92T1G uses SC−59 Style 1 pinout: Pin 1 is Base, Pin 2 is Emitter, and Pin 3 is Collector - confirmed in the onsemi mechanical case outline (Case 318D, Issue J, Feb 2024). This arrangement is standardized across SC−59 PNP transistors and differs from NPN variants. Correct orientation is essential to avoid reverse-bias damage during PCB assembly and functional testing of the NSVMSB92T1G.
