Product details
Overview
S1KLSHRVG from Taiwan Semiconductor is a 1.2A, 800V repetitive peak reverse voltage (VRRM) standard surface-mount silicon rectifier diode in SOD-123HE package, featuring 50A peak forward surge current (IFSM), 175°C maximum junction temperature, and low 1.3V forward voltage at 1.2A - used in DC-DC converter output stages for efficient unidirectional power conversion.
For engineers reviewing the S1KLSHRVG datasheet, S1KLSHRVG pinout, S1KLSHRVG application, or S1KLSHRVG equivalent, key selection criteria include VRRM = 800V, IF = 1.2A, thermal resistance RθJL = 46°C/W, moisture sensitivity level 1, and SOD-123HE footprint compatibility with automated placement systems.
Technical Context
This single-die standard rectifier operates as a unidirectional current switch with cathode-band polarity indication, optimized for high-efficiency switching-mode power supplies where low conduction loss and robust surge handling are required. Its 1.3V VF at 1.2A and 5µA reverse leakage at 25°C support stable DC output regulation under load.
The SOD-123HE package enables compact board layout with JESD201 Class 2 whisker resistance, UL 94V-0 molding compound, and matte tin-plated leads compliant with J-STD-002 solderability - all validated for industrial ambient temperature ranges from –55°C to +175°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - supports input rectification in 400–600V AC line-derived SMPS designs without breakdown risk |
| IF | 1.2 A continuous - sustains steady-state output current in low-to-medium power DC-DC converters |
| IFSM | 50 A (8.3 ms half-sine) - withstands inrush and transient surges during startup or fault conditions |
| VF | ≤1.3 V @ 1.2 A, 25°C - minimizes conduction loss and thermal rise in high-duty-cycle operation |
| RθJL | 46 °C/W - enables direct PCB copper pad heat sinking for reliable thermal management |
| TJ(max) | 175 °C - allows operation in thermally constrained enclosures without derating below full current |
| MSL | Level 1 (per J-STD-020) - no floor life limitation or bake requirement before reflow assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L08U | VRRM = 800V, IF = 1A, VF = 1.15V @ 1A - lower current rating, slightly lower VF | Not suitable for continuous 1.2A loads; requires derating above 85°C ambient | Select when prioritizing lowest VF over current headroom in thermally managed 1A designs |
| ON Semi MUR108 | VRRM = 800V, IF = 1A, IFSM = 30A - lower surge rating, TO-220AC package | Requires through-hole assembly and larger board area; unsuitable for high-density SMT layouts | Choose only if legacy TO-220 footprint must be retained and surge margin is secondary |
Compared with STTH1L08U and MUR108, S1KLSHRVG uniquely delivers 1.2A continuous current in SOD-123HE with MSL Level 1 and 50A surge capability - making it optimal for space-constrained, high-reliability SMT power supplies requiring no derating at full rated current.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of the S1KLSHRVG?
The S1KLSHRVG has a VRRM of 800 V, confirmed in the Absolute Maximum Ratings table on page 2 of the official Taiwan Semiconductor datasheet (Version H2103). This rating defines the highest reverse voltage the device can block repeatedly without breakdown, making S1KLSHRVG suitable for 400–600V AC line-derived applications with safety margin. It is part of the S1DLS–S1MLS family where 'K' denotes the 800V grade.
Does the S1KLSHRVG meet RoHS and halogen-free requirements?
Yes, the S1KLSHRVG is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. The device uses matte tin-plated leads and UL 94V-0 molding compound, satisfying environmental compliance for export and industrial certification. These attributes are verified for the SOD-123HE package variant shipped as S1KLSHRVG.
What is the forward voltage (VF) specification for the S1KLSHRVG at rated current?
The S1KLSHRVG has a maximum forward voltage of 1.3 V at IF = 1.2 A and TJ = 25°C, per the ELECTRICAL SPECIFICATIONS table (page 2). This value is measured under pulsed conditions (PW = 0.3 ms) and represents worst-case conduction loss. At elevated temperatures or lower currents, VF decreases - critical for calculating thermal rise in S1KLSHRVG-based power stages.
Is the S1KLSHRVG suitable for automated SMT assembly?
Yes, the S1KLSHRVG is explicitly designed for automated placement, as noted in its FEATURES list. Its SOD-123HE package, MSL Level 1 rating (no floor life restriction), and J-STD-002-compliant matte tin leads ensure compatibility with standard reflow profiles and high-speed pick-and-place equipment. No pre-bake or special handling is required prior to SMT assembly of S1KLSHRVG.
What is the junction-to-lead thermal resistance (RθJL) of the S1KLSHRVG?
The S1KLSHRVG has a typical RθJL of 46°C/W, measured with the device mounted on a 5 mm × 5 mm copper pad PCB per JEDEC standards. This parameter quantifies thermal conduction from die to lead frame and directly impacts steady-state temperature rise. For S1KLSHRVG operating at 1.2A, this value enables accurate thermal modeling when designing copper pour areas or selecting board stack-ups.
