Product details

Overview

DSS5160V from Diodes Incorporated is a PNP epitaxial planar bipolar junction transistor in SOT-563 package, rated for -60 V V_CEO, -1 A continuous collector current, and ultra-low -160 mV V_CE(SAT) at I_C = -100 mA / I_B = -1 mA. It serves as a high-efficiency low-side switch in portable power management and LED driver circuits.

For engineers reviewing the DSS5160V datasheet, DSS5160V pinout, DSS5160V application, or DSS5160V equivalent, key selection criteria include verified V_CE(SAT) performance at 1 A, thermal resistance of 208 °C/W on FR-4, and compatibility with automated SMT assembly in space-constrained designs.

Technical Context

This PNP transistor employs epitaxial planar die construction to achieve stable h_FE (100–200) across -1 mA to -1 A collector current and supports fast switching with 80 ns turn-on and 260 ns turn-off times under pulsed conditions (300 μs, ≤2% duty cycle). Its low R_CE(SAT) of 330 mΩ at I_C = -1 A / I_B = -100 mA enables minimal conduction loss in battery-powered load control.

The device operates across -55 °C to +150 °C, with V_(BR)CEO = -60 V and V_(BR)CBO = -80 V ensuring robust blocking capability. Its f_T of 150 MHz confirms suitability for medium-speed digital switching rather than RF amplification.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	-60 V - Maximum safe collector-emitter voltage before breakdown in common-emitter configuration.
I_C (cont.)	-1 A - Continuous DC collector current rating; defines maximum steady-state load drive capability.
V_CE(SAT)	-160 mV @ I_C = -100 mA / I_B = -1 mA - Confirmed low saturation voltage enabling <160 mW conduction loss per switch event.
h_FE	100 min @ I_C = -1 A - Minimum DC current gain ensures reliable base drive margin at full load.
R_θJA	208 °C/W - Thermal resistance from junction to ambient on standard FR-4 PCB; determines max power dissipation at given T_A.
f_T	150 MHz - Current gain-bandwidth product confirming usable switching speed up to ~10–20 MHz square-wave operation.
t_off	260 ns - Total turn-off time including 225 ns storage time; critical for PWM frequency selection in DC-DC or LED dimming.

Pinout & Package

Package: SOT-563 - ultra-small surface-mount plastic package (2.2 × 1.2 mm footprint), lead-free/RoHS compliant, moisture sensitivity level 1, weight ≈ 0.003 g.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 5, 6	Emitter (common)	Internally tied emitter terminals; provides low-inductance, high-current emitter path for improved saturation stability.
3	Base	Single base connection; requires ≥100 mA base drive for full 1 A collector conduction with guaranteed V_CE(SAT).
4	Collector	Output terminal; connected to load return path in low-side switch configurations; handles full load current.

Key Features

Feature	Design Value
Ultra-low V_CE(SAT)	-160 mV at 100 mA enables >98% efficiency in 3.3 V logic-level load switches.
SOT-563 footprint	2.2 × 1.2 mm outline allows placement in dense portable PCB layouts where space is constrained to <3 mm².
Epitaxial planar construction	Ensures tight parameter distribution (h_FE, V_CE(SAT)) across production lots for consistent BOM performance.
Lead-free & "Green" compound	UL 94V-0 molded plastic with matte tin finish meets RoHS and automotive ELV compliance without SnPb reflow concerns.

Use Scenario: Constant-current LED backlight in handheld medical display with 5 V supply.

IC Role / Device Role / Timing Role: Linear current sink regulating LED string via base-controlled collector current.

Use Value: Stable h_FE (150 typ. @ 500 mA) enables precise analog current setting without feedback loop complexity.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DSS4160V	Complementary NPN type; +60 V V_CEO, +1 A I_C, +160 mV V_CE(SAT) - identical saturation performance but opposite polarity.	Used in high-side switch configurations where emitter connects to supply rail; not interchangeable without circuit redesign.	Select when topology requires NPN sourcing instead of PNP sinking, e.g., active-high enable paths.
MMBT4403	Higher V_CEO (-40 V), lower I_C (-600 mA), higher V_CE(SAT) (-300 mV @ 100 mA); SOT-23 package (larger footprint).	Limited to sub-500 mA loads; less suitable for 1 A battery-switching due to thermal derating and higher conduction loss.	Acceptable only if peak load current stays below 500 mA and board area permits SOT-23 vs. SOT-563 size reduction.

Compared with DSS4160V, this part offers complementary polarity for dual-rail designs; compared with MMBT4403, it delivers 47% lower V_CE(SAT) at 1 A and 30% smaller footprint-critical for miniaturized portable systems.

FAQ

What is the maximum continuous collector current for DSS5160V?

The DSS5160V is rated for -1 A continuous collector current at T_A = 25 °C with proper PCB copper pour. Derating applies above 25 °C per Fig. 1: at 85 °C ambient, max I_C drops to approximately -650 mA due to 208 °C/W thermal resistance and 600 mW power limit.

Is DSS5160V pin-compatible with standard SOT-23 or SC-70 packages?

No. DSS5160V uses the SOT-563 package (6-pin, dual-emitter layout), which is physically distinct from 3-pin SOT-23 or SC-70. Pin 1–2–5–6 are internally shorted emitters; pin 3 is base; pin 4 is collector. Direct replacement requires PCB layout revision.

Does DSS5160V require a base resistor in switching applications?

Yes. To ensure saturation at I_C = -1 A, a base current of -100 mA is required (I_C/I_B = 10). A series base resistor must be sized to deliver this current from the driving GPIO, considering V_BE(SAT) = -1.1 V and driver voltage swing.

Can DSS5160V be used in linear regulator applications?

It is not optimized for linear regulation. While V_CE(SAT) is low, its h_FE variation with temperature and current (Fig. 3) and lack of built-in thermal shutdown make it unsuitable as a pass element. Use only in saturated-switch mode with defined on/off states.
