Diodes Incorporated DSS5160TQ-7

Overview

DSS5160TQ from Diodes Incorporated is a PNP bipolar junction transistor (BJT) optimized for automotive-grade medium-power switching and amplification, featuring -60 V V_CEO, -1 A continuous collector current, and low -175 mV V_CE(SAT) at I_C = -100 mA / I_B = -1 mA. It is AEC-Q101 qualified and housed in an SOT23 package for space-constrained engine control and body electronics.

For engineers reviewing the DSS5160TQ datasheet, DSS5160TQ pinout, DSS5160TQ application, or DSS5160TQ equivalent, key selection criteria include its -60 V breakdown rating, low saturation voltage under high-current drive, thermal performance on FR-4 PCBs, and automotive qualification status for under-hood reliability.

Technical Context

This PNP BJT uses epitaxial planar die construction to achieve stable h_FE of 200 at I_C = -1 mA and 100 at I_C = -1 A, enabling predictable gain across operating conditions. Its -1.1 V V_BE(SAT) at I_C = -1 A supports robust base drive in saturated-switching configurations.

The device operates across -55°C to +150°C with R_θJA = 79°C/W under pulsed conditions and 172°C/W in steady-state, reflecting thermal design trade-offs between PCB layout and duty cycle. Safe Operating Area (SOA) curves confirm capability for 100 µs to DC operation up to -1 A at -60 V.

FAQ

What is the maximum safe operating voltage for DSS5160TQ in automotive load-dump conditions?

The DSS5160TQ has a -60 V V_CEO rating and -80 V V_CBO, providing 20 V margin above standard 12 V automotive nominal systems. It meets ISO 7637-2 Pulse 5a (load dump) requirements up to +35 V when used with appropriate clamping, but must be paired with TVS protection for full 12 V system compliance.

Can DSS5160TQ replace a generic PNP transistor like PN2907 in an existing design?

Yes, but only after verifying pin compatibility (SOT23 vs TO-92), thermal layout (R_θJA = 172°C/W on standard PCB), and drive capability: DSS5160TQ requires -100 mA base current for full -1 A saturation, whereas PN2907 typically needs less. Layout revision and base resistor recalculation are mandatory.

Does DSS5160TQ support PWM frequencies above 20 kHz for motor control?

With a 150 MHz f_T and 265 ns total turn-off time, DSS5160TQ supports PWM switching up to ~100 kHz in linear or partially saturated modes. However, for hard-switched 20+ kHz motor gate driving, its 230 ns storage time may cause shoot-through risk-use only in low-side or buffered configurations with careful dead-time management.

Is PPAP documentation available for DSS5160TQ?

Yes-DSS5160TQ is PPAP capable per Diodes Incorporated's automotive compliance program. Aetrix Electronics can provide Level 3 PPAP packages including PSW, control plans, measurement system analysis, and process flow diagrams upon request for qualified OEM programs.
