Product details
Overview
NSV30100LT1G from onsemi is a PNP bipolar junction transistor (BJT) optimized for low-voltage, high-speed switching in power management circuits. It delivers −30 V VCEO, −2.0 A ICM, 40–300 hFE (DC current gain), <−0.65 V VCE(sat) at −2.0 A, and operates across −55 °C to +150 °C. It is used in DC-DC converters and automotive airbag deployment systems.
For engineers reviewing the NSV30100LT1G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q101 qualification, SOT-23 package with verified Style 6 pinout, low saturation voltage under high-current pulsed conditions, and thermal resistance of 176 °C/W with 1.0 × 1.0 inch copper pad.
Technical Context
This device belongs to onsemi's e2PowerEdge family of low VCE(sat) transistors, engineered for energy-efficient control in battery-powered and automotive systems. Its linear gain (Beta) supports analog amplifier use, while high hFE enables direct drive from PMU outputs without external amplification.
The NSV30100LT1G features two distinct thermal dissipation ratings: 310 mW with minimal PCB pad (FR-4), and 710 mW with 1.0 × 1.0 inch copper pad-reflecting design dependency on layout-level thermal management. Its safe operating area (SOA) is defined for single-pulse durations up to 10 seconds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −30 V - Maximum collector-emitter blocking voltage before breakdown; defines usable supply rail headroom in PNP switch configurations. |
| ICM | −2.0 A - Peak pulsed collector current capability; supports short-duration load switching in motor drivers and airbag initiators. |
| VCE(sat) | <−0.65 V at −2.0 A/−0.2 A - Ultra-low saturation voltage minimizes conduction loss and heat generation in high-current switching nodes. |
| hFE | 40–300 - Wide DC current gain range across operating points; enables stable biasing from low-drive digital outputs (e.g., PMU GPIO). |
| RθJA | 176 °C/W - Thermal resistance with 1.0 × 1.0 inch copper pad; determines maximum allowable power dissipation at ambient temperature. |
| TJ Range | −55 °C to +150 °C - Extended junction temperature range confirms suitability for under-hood automotive environments. |
Pinout & Package
SOT-23 (TO-236) surface-mount package, 2.90 mm × 1.30 mm × 1.00 mm body size, 1.90 mm lead pitch, Pb-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input terminal; requires −0.2 A base current to saturate at −2.0 A collector current per datasheet Figure 5. |
| 2 | Emiter | Current source terminal; connected to higher potential rail (e.g., battery+) in high-side switch topology. |
| 3 | Collector | Switched output terminal; sinks load current to ground or lower-potential node in typical PNP configuration. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 Qualified | Validated for automotive applications including airbag deployment and instrument cluster; supports PPAP documentation requirements. |
| Low VCE(sat) | ≤ −0.65 V at −2.0 A ensures <1.3 W conduction loss, reducing heatsink need in space-constrained portable and automotive modules. |
| e2PowerEdge Family | Optimized for low-voltage, high-efficiency switching in battery-powered systems where <3.3 V rails are common. |
| High hFE Linearity | hFE remains ≥80 at −1.0 A, enabling predictable analog gain in sensor interface or precision current mirror circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP low VCE(sat) transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBT3906LT1G | Lower ICM (−200 mA), higher VCE(sat) (−0.4 V @ −50 mA), no AEC-Q101 qualification | General-purpose logic-level switching only; unsuitable for automotive or >1 A loads | Select when cost sensitivity outweighs current/power requirements and automotive qualification is unnecessary. |
| PN2907A | Through-hole TO-92, −600 mA IC, −1.6 V VCE(sat) @ −500 mA, no Pb-free or AEC-Q101 status | Legacy prototyping or low-volume industrial controls; incompatible with SMT assembly | Choose only for manual assembly or legacy board rework where SOT-23 footprint and automotive compliance are not required. |
Compared with MMBT3906LT1G and PN2907A, the NSV30100LT1G provides 3.3× higher peak current, 2.5× lower saturation voltage at rated load, and certified automotive qualification-making it uniquely suitable for modern high-reliability, high-density power switching.

FAQ
Is NSV30100LT1G still in production?
No, the NSV30100LT1G is officially marked as discontinued per onsemi's January 2026 datasheet revision. However, Aetrix Electronics maintains active inventory and offers lifecycle support-including last-time buy planning and cross-reference guidance-for customers continuing to use NSV30100LT1G in legacy designs.
What does the "NSV" prefix indicate for NSV30100LT1G?
The "NSV" prefix identifies NSV30100LT1G as a variant meeting automotive-specific site and process control requirements. It confirms AEC-Q101 qualification and PPAP capability-critical for deployment in safety-critical automotive subsystems like airbag controllers and instrument clusters.
Can NSV30100LT1G replace NSS30100LT1G in existing designs?
Yes, NSV30100LT1G and NSS30100LT1G share identical electrical specifications, SOT-23 package, Style 6 pinout, and thermal characteristics. The NSV version adds automotive-specific process controls and qualification-making it a drop-in upgrade for NSS30100LT1G in automotive applications, though not vice versa for PPAP-compliant builds.
What is the maximum continuous collector current rating for NSV30100LT1G?
The NSV30100LT1G has a maximum continuous collector current (IC) rating of −1.0 A at TA = 25 °C. This rating assumes adequate PCB copper area (1.0 × 1.0 inch pad) to maintain RθJA = 176 °C/W; derating applies above 25 °C ambient.
Does NSV30100LT1G support analog amplifier applications?
Yes, the NSV30100LT1G supports analog amplifier use due to its linear DC current gain (hFE) behavior across collector current-documented in Figure 1 of the datasheet. Its hFE remains ≥80 from −10 mA to −1.0 A, enabling stable biasing in current mirrors, sensor interfaces, and low-noise preamplifier stages.
