Product details

Overview

S15KLWHRVG from Taiwan Semiconductor is a 1.5A, 800V repetitive peak reverse voltage (V_RRM) surface-mount standard rectifier in SOD-123W package, designed for high-efficiency DC/DC conversion and switching-mode power supplies. It delivers 50A surge capability (I_FSM), operates up to 175°C junction temperature, and exhibits 0.98V typical forward voltage at 1.5A/25°C.

For engineers reviewing the S15KLWHRVG datasheet, S15KLWHRVG pinout, S15KLWHRVG application, or S15KLWHRVG equivalent, key selection criteria include V_RRM = 800V, I_F = 1.5A, thermal resistance R_θJA = 85°C/W on 5mm × 5mm Cu pad, and moisture sensitivity level 1 compliance per J-STD-020.

Technical Context

This single-die standard rectifier uses planar epitaxial construction for stable reverse recovery and low leakage. Its 800V V_RRM rating targets mid-voltage industrial SMPS and offline auxiliary supplies where 600–1000V devices are required but higher-cost ultra-fast or soft-recovery types are unnecessary.

Thermal performance is defined with standardized PCB mounting (5mm × 5mm copper pad); R_θJL = 29°C/W enables efficient heat transfer to the PCB lead frame, while R_θJC = 31°C/W confirms case-to-junction conduction path integrity under steady-state operation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	800 V - Maximum repetitive reverse blocking voltage; defines usable input voltage range in bridge or flyback snubber circuits
I_F	1.5 A - Continuous average forward current rating at 75°C ambient on standard PCB; sets output power limit in compact converters
I_FSM	50 A - Peak non-repetitive surge current (8.3 ms half-sine); supports inrush and transient overload handling without failure
V_F @ 1.5A, 25°C	0.98 V (typ), 1.10 V (max) - Directly determines conduction loss and thermal rise in high-duty-cycle applications
T_J max	+175 °C - Enables reliable operation in enclosed, high-ambient industrial environments without derating penalties
C_J	10 pF @ 1 MHz, 4 V - Low junction capacitance minimizes switching noise and EMI in high-frequency (>100 kHz) topologies

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1L08U	V_RRM = 800 V, I_F = 1 A, faster recovery (t_rr = 75 ns), higher V_F (1.15 V @ 1 A)	Better suited for high-frequency (≥300 kHz) SMPS where reverse recovery loss dominates	Select STTH1L08U only if t_rr reduction justifies 33% lower I_F rating and higher conduction loss
ON Semi MUR108	V_RRM = 800 V, I_F = 1 A, ultrafast recovery (t_rr ≈ 50 ns), TO-220AC package	Requires through-hole mounting and heatsinking; unsuitable for SMT-only production	Choose MUR108 only when board-level thermal management permits larger footprint and higher assembly cost

Compared with STTH1L08U and MUR108, the S15KLWHRVG offers higher continuous current (1.5 A vs. 1 A) in an SMT-optimized SOD-123W package, making it preferable for space-constrained, medium-frequency (<200 kHz) industrial power supplies where surge robustness and thermal efficiency outweigh ultrafast recovery needs.

FAQ

What is the maximum junction temperature rating for S15KLWHRVG?

The S15KLWHRVG has a maximum junction temperature (T_J) of +175°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating allows uninterrupted operation in high-ambient industrial environments such as motor drive enclosures or sealed power supplies. The S15KLWHRVG maintains specified electrical performance across its full –55°C to +175°C junction temperature range, and thermal derating begins only above 75°C ambient on standard PCB mounting.

Does S15KLWHRVG have a halogen-free construction?

Yes, the S15KLWHRVG is halogen-free in accordance with IEC 61249-2-21, as confirmed in the "Features" section of the Taiwan Semiconductor datasheet. Its molding compound contains no brominated or chlorinated flame retardants, and all materials comply with both RoHS Directive 2011/65/EU and TSC's internal halogen-free policy. This makes the S15KLWHRVG suitable for export to markets with strict environmental compliance requirements, including automotive and medical-adjacent industrial equipment.

What is the forward voltage of S15KLWHRVG at 1.5 A and 125°C?

The S15KLWHRVG exhibits a typical forward voltage (V_F) of 0.87 V and a maximum of 1.05 V at 1.5 A and 125°C junction temperature, per the Electrical Specifications table. This lower V_F at elevated temperature reflects improved conduction efficiency under thermal stress-critical for sustained load conditions in enclosed power modules. The S15KLWHRVG's V_F remains within specification across its full operating temperature range, ensuring predictable power loss modeling.

Is S15KLWHRVG pin-compatible with other SOD-123W rectifiers?

The S15KLWHRVG uses the industry-standard SOD-123W package with anode/cathode terminals in fixed physical orientation, matching JEDEC MO-203AA outline dimensions. While mechanical pinout is identical to other SOD-123W rectifiers (e.g., ON Semi M108, Diodes Inc. BAS21), electrical compatibility depends on V_RRM, I_F, and thermal specs-not just footprint. The S15KLWHRVG must be evaluated individually for replacement; its 800 V V_RRM and 1.5 A rating are not shared by all SOD-123W parts.

What is the moisture sensitivity level (MSL) of S15KLWHRVG?

The S15KLWHRVG is rated at Moisture Sensitivity Level 1 (MSL 1) per J-STD-020, meaning it may be stored indefinitely at ≤30°C/85% RH without baking prior to reflow soldering. This eliminates dry-pack requirements and floor-life tracking in SMT production, reducing handling overhead. The S15KLWHRVG's MSL 1 status is confirmed in the "Features" list and applies to the full S15DLW–S15MLW series, supporting high-yield, low-risk automated assembly.
