Product details

Overview

S1MLSHRVG from Taiwan Semiconductor is a 1.2A, 1000V repetitive peak reverse voltage (V_RRM) surface-mount standard rectifier in SOD-123HE package, featuring 50A peak forward surge current (I_FSM), 1.3V max forward voltage at 1.2A, and 175°C maximum junction temperature - deployed in DC-DC converters and switching-mode inverters.

For engineers reviewing the S1MLSHRVG datasheet, S1MLSHRVG pinout, S1MLSHRVG application, or S1MLSHRVG equivalent, key selection criteria include V_RRM = 1000V, I_F = 1.2A, thermal resistance R_θJA = 86°C/W, moisture sensitivity level 1, and RoHS/halogen-free compliance per IEC 61249-2-21.

Technical Context

This single-die standard rectifier operates with unidirectional conduction and cathode-band polarity indication. Its 1000V V_RRM rating supports high-voltage DC bus conditioning, while 50A I_FSM enables robust handling of transient surges in power supply startup and fault conditions.

Thermal performance is characterized by R_θJL = 46°C/W and R_θJA = 86°C/W on a 5mm × 5mm Cu pad PCB - enabling reliable operation up to T_J = 175°C without forced cooling in space-constrained industrial power stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	1000 V - Withstands 1000V repetitive reverse voltage, suitable for 800V DC-link applications with safety margin
I_F	1.2 A - Continuous average forward current rating at T_A = 25°C, derates above 25°C per curve Fig.1
I_FSM	50 A - Peak non-repetitive surge current (8.3ms half-sine), supports inrush and fault-current stress
V_F max	1.3 V @ I_F = 1.2A, T_J = 25°C - Low conduction loss improves efficiency in high-frequency SMPS designs
T_J max	175 °C - Enables operation in high-ambient environments such as enclosed industrial power supplies
R_θJA	86 °C/W - Measured on 5mm × 5mm Cu pad; defines thermal design baseline for PCB layout

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1L06S	V_RRM = 600V, I_F = 1A, V_F = 1.15V typ @ 1A - lower voltage rating and current, slightly lower V_F	Not suitable for 1000V systems; acceptable only in ≤400V DC-link applications	Select only if system V_RRM margin permits reduction and thermal budget allows higher V_F-related loss
ON Semi MUR120RLG	V_RRM = 200V, I_F = 1A, ultrafast recovery t_rr = 75ns - faster switching but insufficient voltage rating	Designed for high-frequency snubberless topologies; incompatible with 1000V reverse stress	Use only where fast recovery is prioritized over voltage capability - not a functional substitute for S1MLSHRVG

Compared with STTH1L06S and MUR120RLG, S1MLSHRVG uniquely delivers 1000V V_RRM at 1.2A continuous current in SOD-123HE - making it the only option among the three qualified for high-voltage industrial DC bus rectification without derating or parallel devices.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for S1MLSHRVG?

The S1MLSHRVG has a V_RRM rating of 1000 V, confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version H2103). This value defines the highest reverse voltage the device can block repeatedly without breakdown under normal operating conditions and is critical for selecting appropriate safety margins in high-voltage power supply designs.

Does S1MLSHRVG have RoHS and halogen-free compliance?

Yes, S1MLSHRVG is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. These certifications are verified for the SOD-123HE package variant and apply to the full S1DLS–S1MLS family, including S1MLSHRVG.

What is the forward voltage (V_F) specification for S1MLSHRVG at rated current?

S1MLSHRVG exhibits a maximum forward voltage of 1.3 V at I_F = 1.2 A and T_J = 25°C, per the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and represents worst-case conduction loss - essential for calculating thermal rise and efficiency in power stage design.

What is the moisture sensitivity level (MSL) of S1MLSHRVG?

S1MLSHRVG is rated MSL Level 1 per J-STD-020, meaning it may be stored indefinitely at ambient conditions (<30°C / 60% RH) and requires no baking prior to reflow soldering. This eliminates handling complexity in high-volume SMT lines and is confirmed in the FEATURES section of the official datasheet.

Is S1MLSHRVG suitable for use in automotive applications?

No - Taiwan Semiconductor explicitly states that products in the S1DLS–S1MLS series, including S1MLSHRVG, are not designed for medical, life-saving, or life-sustaining applications. While the device meets industrial-grade reliability (T_J = −55°C to +175°C), it lacks AEC-Q101 qualification and automotive-specific testing, so it is not recommended for automotive power systems.
