Product details
Overview
NSL12AWT1 from onsemi is a PNP silicon low-VCE(sat) transistor in SC-88 (SOT-363) package, rated for −12 VCEO, −2.0 A continuous collector current, and 170 mV typical VCE(sat) at −1.0 A, designed for high-efficiency switching in battery-powered portable electronics including power management circuits and load switches.
For engineers reviewing the NSL12AWT1 datasheet, pinout, applications, or equivalent options, key selection criteria include verified low saturation voltage under high current, thermal performance with 192°C/W RJA (1″ pad), dual-collector configuration for parallel current handling, and Pb-free RoHS-compliant packaging suitable for space-constrained consumer and industrial designs.
Technical Context
This device implements a dual-collector PNP bipolar junction transistor architecture with shared emitter and base terminals across two identical transistor elements in one SC-88 package. Its design enables current sharing without external balancing components while maintaining tight VCE(sat) matching (±5% typical) between channels.
It operates within −55°C to +150°C junction temperature range and supports pulsed operation up to 1.4 W (single pulse <10 sec). The 100 MHz fT and 50 pF Cobo confirm suitability for medium-speed switching applications where low conduction loss dominates over ultra-high-frequency response.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −12 V - Maximum safe collector-emitter reverse bias before breakdown in open-base condition. |
| IC Continuous | −2.0 A - Sustained DC current per channel without exceeding thermal limits on standard FR-4 PCB (1″ pad). |
| VCE(sat) @ −1.0 A | −0.17 V typical - Low conduction loss enabling >95% efficiency in 3.3 V–5 V battery-switching paths. |
| RJA (1″ pad) | 192°C/W - Thermal resistance enabling 650 mW dissipation at TA = 25°C with minimal heatsinking. |
| fT | 100 MHz - Sufficient gain-bandwidth for PWM frequencies up to ~10 MHz with stable switching behavior. |
| hFE @ −1.0 A | 100–160 - Predictable DC current gain supporting fixed-base-drive designs with ±20% IB tolerance. |
| Cobo | 50 pF - Low output capacitance minimizing switching energy loss and gate drive burden in discrete driver stages. |
Pinout & Package
NSL12AWT1 uses the SC-88 (SOT-363) surface-mount package (Case 419B, Style 20), measuring 2.00 × 1.25 × 0.90 mm with 0.65 mm lead pitch. It integrates two identical PNP transistor units sharing common emitter and base connections, with six terminals configured for dual-collector operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6 | Collector (dual-channel) | Four independent collector terminals-two per transistor element-enabling parallel connection or separate routing for redundancy or current splitting. |
| 3 | Base | Single shared base terminal controlling both PNP elements simultaneously; requires −20 mA drive for full −1.0 A per channel. |
| 4 | Emitter | Common emitter node tied to system ground or negative rail; serves as reference for both transistor channels. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) | 170 mV typical at −1.0 A reduces I²R losses by >40% vs. standard PNP transistors, extending battery runtime in portable devices. |
| Dual-collector topology | Four collector pins support flexible PCB layout-either paralleled for 4 A peak capability or isolated for dual-load control with single base drive. |
| Pb-free & RoHS compliance | Meets global environmental regulations without compromising thermal or electrical performance; marked "G" for lead-free identification. |
| High power density | 650 mW dissipation in 2.0 × 1.25 mm footprint enables replacement of larger SOT-23 or SOIC-8 solutions in space-critical designs. |
Applications

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 |
|---|---|---|---|
| DMT3005LKQ | N-channel MOSFET (30 V, 5.5 A, 28 mΩ); requires level-shifting gate drive for high-side use. | Better efficiency above 1 A but adds complexity in gate biasing; unsuitable for direct GPIO drive. | Select when board space allows gate driver IC and efficiency >98% is critical; avoid for simple microcontroller-driven switches. |
| MMBT3906LT1G | Single PNP (−40 V, −200 mA, −400 mV VCE(sat) @ −50 mA); smaller SOT-23 package, lower current rating. | Limited to sub-500 mA loads; higher saturation voltage increases power loss in battery-critical paths. | Use only for signal-level switching or low-current bias networks-not for main power rail control. |
Compared with DMT3005LKQ and MMBT3906LT1G, the NSL12AWT1 uniquely delivers −2.0 A continuous current with −170 mV VCE(sat) in a compact SC-88 package using simple base-drive logic-making it optimal for cost-sensitive, space-constrained, battery-operated PNP switching where MOSFET gate complexity or low-current BJTs are inadequate.

FAQ
What is the maximum continuous collector current rating for NSL12AWT1?
The NSL12AWT1 is rated for −2.0 A continuous collector current per channel at TA = 25°C with a 1″ copper pad on FR-4 PCB. Derating applies above 25°C at 5.2 mW/°C. This rating assumes both collector terminals (pins 1/2/5/6) are used in parallel per channel; actual current capability depends on PCB thermal design and ambient conditions. The NSL12AWT1 datasheet confirms this value under "MAXIMUM RATINGS" with Note 2 referencing the 1″ pad thermal condition.
Does NSL12AWT1 support dual independent transistor operation?
No-the NSL12AWT1 integrates two PNP transistor elements sharing a common base (pin 3) and common emitter (pin 4); its four collector terminals (pins 1, 2, 5, 6) belong to two matched units but cannot be independently controlled. The device functions as a single high-current PNP switch with redundant collector paths-not as two separate transistors. This architecture is confirmed in the "MARKING DIAGRAM" and "STYLE 20" pinout table on page 2 of the NSL12AWT1 datasheet.
What is the typical VCE(sat) of NSL12AWT1 at −1.0 A collector current?
The NSL12AWT1 exhibits −0.17 V typical VCE(sat) at −1.0 A collector current and −20 mA base current, as specified in the "ELECTRICAL CHARACTERISTICS" table under "ON CHARACTERISTICS." This value is measured at TJ = 25°C and reflects the device's optimized low-saturation design for battery-operated applications. The maximum guaranteed value is −0.290 V under the same conditions.
Is NSL12AWT1 RoHS compliant and lead-free?
Yes-NSL12AWT1 is explicitly marked as Pb-free and RoHS compliant in the "Features" section of its datasheet, with additional confirmation in the "ORDERING INFORMATION" table listing "NSL12AWT1G" as the Pb-free variant. The "G" suffix denotes lead-free packaging, and the device meets halogen-free/BFR-free requirements per the manufacturer's compliance documentation.
What package type does NSL12AWT1 use and what are its dimensions?
NSL12AWT1 uses the SC-88 (also known as SOT-363) package, designated Case 419B Style 20. Its physical dimensions are 2.00 mm × 1.25 mm × 0.90 mm with a 0.65 mm lead pitch. This information is documented in the "MECHANICAL CASE OUTLINE" section and "PACKAGE DIMENSIONS" diagram on page 2 of the NSL12AWT1 datasheet, confirming compatibility with standard SOT-363 pick-and-place and reflow processes.
