Product details
Overview
DSS5160T-7 from Diodes Incorporated is a 60V, -1A PNP bipolar junction transistor in SOT23 package, featuring low VCE(sat) of -175 mV at IC = -100 mA / IB = -1 mA, AEC-Q101 qualified for automotive reliability, and optimized for medium-power switching in DC-DC converters and load control circuits.
For engineers reviewing the DSS5160T-7 datasheet, DSS5160T-7 pinout, DSS5160T-7 application, or DSS5160T-7 equivalent, key selection criteria include its -60 V VCEO, -1 A continuous collector current, -175 mV saturation voltage, hFE ≥100 at IC = -1 A, and SOT23 thermal performance with RθJA = 79 °C/W under pulsed conditions.
Technical Context
This PNP transistor uses epitaxial planar die construction to achieve stable gain and low saturation voltage across temperature. Its VCEO = -60 V and VCBO = -80 V support robust blocking in 24V/48V industrial and automotive supply rails.
Designed for high-reliability switching, it delivers fast turn-on (ton = 75 ns) and controlled turn-off (toff = 265 ns), with fT = 150 MHz enabling use in moderate-frequency PWM stages and signal amplification up to ~10 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -60 V - Supports safe operation in 48V automotive and industrial bus systems with margin |
| IC (continuous) | -1 A - Enables direct drive of medium-current loads such as solenoids or LED strings |
| VCE(sat) | -175 mV @ IC = -100 mA / IB = -1 mA - Minimizes conduction loss and self-heating in switching applications |
| hFE | 100 min @ IC = -1 A - Ensures reliable base drive efficiency at full rated current |
| fT | 150 MHz - Allows use in high-speed switching and small-signal amplification up to 10 MHz |
| RθJA (pulsed) | 79 °C/W - Achieved on 15 mm × 15 mm FR4 PCB; enables >500 mW pulsed power handling |
| Package | SOT23 - Standardized footprint compatible with automated placement and reflow processes |
Pinout & Package
Package: SOT23 - Surface-mount plastic package with matte tin-plated copper leadframe, moisture sensitivity level 1, UL 94V-0 rated, weight ≈ 0.008 g.

| B (Base) | Control input for transistor biasing | Requires negative current relative to emitter to enable conduction; supports ≤ -300 mA DC drive |
| C (Collector) | Current sink terminal | Connected to load return path; withstands -60 V reverse bias during off-state |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade temperature cycling (-55°C to +150°C) and mechanical stress |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP medium-power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBT4403-7-F | VCEO = -40 V, VCE(sat) = -0.2 V @ IC = -150 mA - lower voltage rating and higher saturation voltage | Not suitable for 48V bus or high-current (>500 mA) loads due to derated breakdown and conduction loss | Select only for 12V/low-power logic-level switching where cost is primary constraint |
| ZTX653STZ | VCEO = -60 V, IC = -1.5 A, but SOT89 package - larger footprint and higher thermal resistance (RθJA ≈ 120 °C/W) | Acceptable for same voltage/current specs but requires PCB redesign and offers inferior thermal performance on standard FR4 | Choose when higher peak current headroom is needed and board space allows SOT89 mounting |
Compared with MMBT4403-7-F and ZTX653STZ, DSS5160T-7 uniquely balances -60 V rating, -1 A capability, ultra-low -175 mV VCE(sat), and SOT23 thermal efficiency-making it optimal for space-constrained, thermally sensitive 24–48V automotive and industrial switches.

FAQ
What is the maximum continuous collector current for DSS5160T-7?
The DSS5160T-7 supports -1 A continuous collector current at TA = 25°C with proper PCB thermal relief (15 mm × 15 mm, 1 oz copper). Derating applies above 25°C ambient per the published thermal curve; at 100°C ambient, max IC drops to approximately -600 mA under pulsed conditions.
Is DSS5160T-7 suitable for high-frequency switching applications?
Yes - with fT = 150 MHz and turn-on/off times of 75 ns and 265 ns respectively, the device supports clean switching up to ~500 kHz in hard-switched topologies. For >1 MHz operation, gate/base drive strength and layout parasitics become critical limiting factors.
Does DSS5160T-7 require a heatsink in typical applications?
No - under pulsed conditions on a standard 15 mm × 15 mm FR4 PCB, its RθJA = 79 °C/W allows safe operation at up to ~500 mW dissipation without external heatsinking. At full 1 A DC with -175 mV VCE(sat), power dissipation is ~175 mW, well within this limit.
How does the AEC-Q101 qualification impact DSS5160T-7's use in non-automotive designs?
AEC-Q101 qualification confirms extended temperature operation (-55°C to +150°C), enhanced mechanical robustness, and rigorous reliability testing - benefits that directly improve field lifetime and reduce failure rates in demanding industrial, medical, and outdoor equipment, even outside automotive contexts.
