Diodes Incorporated DPLS160V-7

Overview

DPLS160V-7 from Diodes Incorporated is a low V_CE(SAT) PNP bipolar junction transistor in SOT-563 package, rated for -60 V V_CEO, -1 A continuous collector current, and 300 mW power dissipation at 25°C ambient. It delivers ultra-low saturation voltage down to -175 mV at I_C = -1 A / I_B = -100 mA and supports high-reliability automotive applications per AEC-Q101 qualification.

For engineers reviewing the DPLS160V-7 datasheet, DPLS160V-7 pinout, DPLS160V-7 application, or DPLS160V-7 equivalent, key selection criteria include its -160 mΩ R_CE(SAT), 150–220 MHz f_T, AEC-Q101 qualification, SOT-563 footprint compatibility, and complementary pairing with DNLS160V for push-pull switching circuits.

Technical Context

This PNP transistor uses epitaxial planar die construction for stable gain and low leakage. Its V_CE(SAT) remains ≤ -175 mV under high-current switching (I_C = -1 A), enabling efficient low-voltage load control in space-constrained PCBs.

The device exhibits h_FE = 180–325 across I_C = -1 mA to -1 A and maintains f_T ≥ 150 MHz at V_CE = -10 V, supporting fast-switching applications such as LED drivers and power management blocks where speed and saturation loss are critical.

FAQ

What is the maximum allowable junction temperature for DPLS160V-7?

The DPLS160V-7 has an operating junction temperature range of -55°C to +150°C. Its absolute maximum T_J is +150°C, validated per AEC-Q101 test conditions. Derating begins above 25°C ambient per the 417°C/W R_θJA curve in Figure 1, requiring thermal pad layout per AP02001 for sustained 1 A operation.

Is DPLS160V-7 pin-compatible with DNLS160V?

No - DPLS160V-7 (PNP) and DNLS160V (NPN) share identical SOT-563 mechanical footprint and pin numbering, but their internal terminal assignments differ: DPLS160V-7 uses pins 1/2/5/6 as emitter, pin 3 as base, and pin 4 as collector; DNLS160V reverses polarity with pins 1/2/5/6 as collector, pin 3 as base, and pin 4 as emitter.

Does DPLS160V-7 require external base resistors for microcontroller GPIO drive?

Yes - driving the base directly from a 3.3 V or 5 V GPIO requires a series resistor to limit I_B. For full saturation at I_C = -1 A, I_B ≈ -100 mA is needed; a 22 Ω resistor (for 5 V GPIO) or 15 Ω (for 3.3 V) ensures proper bias while staying within GPIO current limits and avoiding excessive base power dissipation.

Can DPLS160V-7 be used in linear regulator pass transistor applications?

It is not recommended - although DPLS160V-7 supports DC operation, its 300 mW power dissipation limit and lack of SOA curves in the datasheet restrict use to switching mode only. Linear regulation would exceed safe operating area under typical dropout and load conditions, risking thermal runaway without additional protection circuitry.
