Product details

Overview

SSL32 V7G from Taiwan Semiconductor is a 3A, 20V repetitive peak reverse voltage Schottky barrier rectifier in DO-214AB (SMC) package, optimized for high-efficiency switching mode power supplies, adapters, and DC-DC converters with low forward voltage drop (≤0.41 V at 3 A, 25°C) and high surge current capability (100 A, 8.3 ms).

For engineers reviewing the SSL32 V7G datasheet, SSL32 V7G pinout, SSL32 V7G application, or SSL32 V7G equivalent, this page delivers verified electrical specs, thermal resistance values (R_θJL = 13°C/W), junction temperature limits (–55°C to +125°C), reverse leakage behavior (≤200 µA at 25°C), and mechanical packaging details per JEDEC DO-214AB.

Technical Context

The SSL32 V7G implements a single-die Schottky structure with guard ring overvoltage protection, enabling robust operation under transient conditions. Its low R_θJA (53°C/W on 16 mm × 16 mm Cu pad) and matte tin-plated leads support automated SMT assembly and reliable thermal management in compact power stages.

Designed for unidirectional conduction, it features polarity indicated by cathode band, moisture sensitivity level 1 (per J-STD-020), and UL 94V-0 molding compound - meeting RoHS and halogen-free compliance requirements without derating in standard ambient conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	20 V - maximum non-repetitive reverse voltage before breakdown; defines safe operating window in flyback/clamp circuits
I_F	3 A continuous - rated average forward current at case temperature ≤75°C; supports sustained load in 24W+ SMPS designs
I_FSM	100 A - peak surge current tolerance for 8.3 ms half-sine; handles inrush and fault transients without failure
V_F	≤0.41 V at I_F = 3 A, T_J = 25°C - enables <1.23 W conduction loss, critical for >90% efficiency targets
R_θJL	13°C/W - low junction-to-lead thermal resistance allows direct PCB copper pour heat sinking without external heatsink
T_J max	+125°C - maximum junction temperature; sets thermal design margin for enclosed or high-ambient environments
I_R	≤200 µA at V_R = 20 V, T_J = 25°C - low leakage preserves standby power in energy-efficient adapters

Pinout & Package

Package: DO-214AB (SMC), surface-mount, single-anode/single-cathode configuration with cathode band marking. Dimensions comply with JEDEC DO-214AB Issue D; recommended pad layout: 6.80 mm × 7.75 mm, 1.95 mm lead width.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay SS32HE3_A/H	V_RRM = 20 V, I_F = 3 A, V_F = 0.5 V (typ) at 3 A - 90 mV higher forward drop than SSL32 V7G	Higher conduction loss reduces efficiency in thermally constrained adapters; same DO-214AB footprint	Acceptable where 0.5 V V_F is tolerable and Vishay supply chain preference exists
ON Semiconductor SB320	V_RRM = 20 V, I_F = 3 A, V_F = 0.52 V (max) at 3 A - 110 mV higher worst-case V_F; R_θJA = 65°C/W vs. 53°C/W	Requires larger copper area or lower ambient to maintain T_J < 125°C at full load	Valid alternative if thermal margin ≥15°C is available and SB320's legacy qualification meets program requirements

Compared with SS32HE3_A/H and SB320, SSL32 V7G delivers the lowest confirmed V_F (≤0.41 V) and best thermal resistance (R_θJA = 53°C/W), making it preferred for space-constrained, high-efficiency 3A rectification where every 10 mV and 5°C/W matters.

FAQ

What is the maximum junction temperature rating for SSL32 V7G?

The SSL32 V7G has a maximum junction temperature (T_J) of +125°C, with an operational range from –55°C to +125°C. This rating is validated under specified thermal conditions using a 16 mm × 16 mm copper pad test board. Designers must ensure actual PCB layout and airflow keep SSL32 V7G junction temperature below this limit during continuous 3 A operation.

Does SSL32 V7G have a guard ring structure?

Yes, SSL32 V7G incorporates a guard ring for overvoltage protection, as explicitly stated in its official features list. This structure mitigates edge breakdown under transient reverse voltage stress, enhancing reliability in switching power supplies subject to ringing or surge events - a distinguishing feature not present in basic Schottky rectifiers.

What is the forward voltage of SSL32 V7G at rated current?

The SSL32 V7G exhibits a maximum forward voltage (V_F) of 0.41 V at I_F = 3 A and T_J = 25°C, per its electrical specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and represents the upper limit for conduction loss calculation in efficiency modeling of power supplies using SSL32 V7G.

Is SSL32 V7G RoHS and halogen-free compliant?

Yes, SSL32 V7G is both RoHS compliant and halogen-free, as confirmed in the official features section. These compliance attributes are integral to its qualification for use in consumer electronics and industrial equipment sold in EU, China, and other regulated markets requiring strict environmental material declarations.

What packaging format is used for SSL32 V7G?

SSL32 V7G is supplied in DO-214AB (SMC) surface-mount package, packed 3,000 units per tape-and-reel. The device uses matte tin-plated leads, conforms to J-STD-002 solderability standards, and carries a cathode band for polarity identification - all verified in the mechanical data and ordering information sections of the official documentation.
