Product details
Overview
S2JFL from Taiwan Semiconductor is a 2 A, 600 V standard surface-mount silicon rectifier diode in SOD-123FL package, featuring glass-passivated junction, low reverse leakage (≤5 µA at 25°C), and 81 °C/W junction-to-lead thermal resistance - used in DC-DC converters and switching-mode inverters.
For engineers reviewing the S2JFL datasheet, S2JFL pinout, S2JFL application, or S2JFL equivalent, key selection criteria include repetitive peak reverse voltage (600 V), forward voltage (0.97 V max at 2 A, 25°C), surge current capability (40 A @ 8.3 ms), thermal performance on PCB, and RoHS/halogen-free compliance for industrial power conversion designs.
Technical Context
The S2JFL is a single-die, unidirectional standard recovery rectifier optimized for medium-voltage switching power supplies. Its glass-passivated junction ensures stable reverse characteristics across temperature, while the SOD-123FL package enables automated placement and meets JESD201 Class 1 whisker resistance.
Electrical behavior is defined by a maximum forward voltage of 1.10 V at 2 A/25°C, reverse current limited to 100 µA at 125°C, and junction capacitance of 10 pF at 4 V - supporting high-frequency operation in compact converter topologies without compromising reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports input rectification in 400 VAC line-derived SMPS with margin |
| IF | 2 A continuous - suitable for output rectification in mid-power DC-DC modules |
| IFSM (8.3 ms) | 40 A - withstands typical inrush and transient surges in offline converters |
| VF (2 A, 25°C) | 0.97 V max - limits conduction loss to ≤1.94 W at full load |
| RθJL | 81 °C/W - enables thermal management with minimal copper pad area on PCB |
| TJ max | +150 °C - allows operation in sealed or high-ambient industrial enclosures |
| IR (25°C) | ≤5 µA - minimizes standby power loss in energy-sensitive applications |
Pinout & Package

Applications
| DC–DC Converter Output Rectification | Switching Mode Inverter Input Stage |
|---|---|
Use Scenario: Secondary-side rectification in isolated 24–48 V output flyback or forward converters delivering up to 2 A. IC Role / Device Role / Timing Role: Power diode conducting during transformer reset phase; handles continuous 2 A forward current and blocks reflected primary-side voltage spikes. Use Value: Low 0.97 V forward drop reduces conduction loss; 600 V VRRM accommodates reflected voltage margins in 380 V bus systems. | Use Scenario: AC input bridge replacement or half-wave rectification in 100–240 VAC-fed inverters for motor drives or UPS. IC Role / Device Role / Timing Role: Standard recovery rectifier handling line-frequency and switching transients; operates in non-synchronous mode with no gate control required. Use Value: 40 A surge rating absorbs inrush from bulk capacitors; 150 °C max junction temperature supports enclosed thermal environments. |
| Industrial Power Supply Front-End | LED Driver Bulk Rectification |
Use Scenario: Input rectification stage in DIN-rail mounted 24 V/5 A industrial PSUs with universal AC input. IC Role / Device Role / Timing Role: Single-phase rectifier in discrete bridge or voltage-doubler configuration; interfaces directly with EMI filter and bulk capacitor. Use Value: 5 µA reverse leakage at 25°C minimizes no-load power draw; SOD-123FL footprint enables dense layout without thermal vias. | Use Scenario: High-efficiency constant-current LED driver for street lighting, operating from 277 VAC line. IC Role / Device Role / Timing Role: Primary rectifier converting AC line to high-voltage DC bus prior to buck or flyback regulation. Use Value: 600 V rating covers 277 VAC × √2 + safety margin; halogen-free construction satisfies outdoor luminaire material compliance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR260 | Ultrafast recovery (trr ≈ 50 ns vs. S2JFL's ~2 µs), higher VF (1.25 V), TO-220AC package | Better suited for high-frequency PFC stages; requires heatsink mounting and larger board area | Select when switching frequency exceeds 100 kHz and reverse recovery loss dominates efficiency |
| Vishay VS-2EY60 | Same 600 V/2 A rating, DO-214AC (SMA) package, slightly higher IR (10 µA) | Larger footprint and higher RθJA; compatible with manual or wave solder but not optimized for high-speed pick-and-place | Prefer when legacy SMA layout exists or where moisture sensitivity level is not constrained |
Compared with MUR260 and VS-2EY60, the S2JFL offers superior manufacturability (MSL-1, SOD-123FL), lower leakage, and tighter thermal resistance - making it optimal for space-constrained, high-volume industrial DC-DC modules where standard recovery speed is sufficient.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of the S2JFL?
The S2JFL has a maximum repetitive peak reverse voltage (VRRM) of 600 V, as specified in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version B2103). This rating defines the highest reverse voltage the device can block repeatedly without breakdown under normal operating conditions, and is critical for ensuring safe operation in 277 VAC or 400 VDC bus applications where voltage transients must be accommodated.
Does the S2JFL have a halogen-free construction?
Yes, the S2JFL is halogen-free in accordance with IEC 61249-2-21, as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. This compliance ensures the molding compound contains no chlorine or bromine-based flame retardants, meeting environmental requirements for export to the EU, Japan, and other regulated markets - a verified specification confirmed in the official product documentation.
What is the forward voltage (VF) of the S2JFL at 2 A and 25°C?
The forward voltage (VF) of the S2JFL is guaranteed to be no more than 1.10 V at 2 A and 25°C, with a typical value of 0.97 V, per the ELECTRICAL SPECIFICATIONS table. This parameter directly impacts conduction losses in power circuits; for example, at 2 A continuous, worst-case power dissipation is 2.2 W - a key factor in thermal design for compact PCB layouts.
Is the S2JFL suitable for automated SMT assembly?
Yes, the S2JFL is explicitly designed for automated placement, as noted in its FEATURES list. Its SOD-123FL package, MSL-1 moisture sensitivity rating, and J-STD-002-compliant matte tin-plated leads ensure compatibility with standard high-speed pick-and-place machines and lead-free reflow profiles - eliminating pre-bake steps and supporting high-yield manufacturing.
What is the junction-to-lead thermal resistance (RθJL) of the S2JFL?
The junction-to-lead thermal resistance (RθJL) of the S2JFL is 81 °C/W, measured with the device mounted on a 5 mm × 5 mm copper pad test board, as published in the THERMAL PERFORMANCE section. This value enables accurate estimation of junction temperature rise above lead temperature and informs thermal pad sizing decisions in thermally constrained industrial power designs.
