Product details
Overview
RS1JFL from Taiwan Semiconductor is a 600 V, 1 A fast recovery surface-mount rectifier in SOD-123FL package, featuring 250 ns reverse recovery time, 1.04 V forward voltage at 1.0 A/25°C, and 11 pF junction capacitance. It serves as a primary-side output rectifier in high-frequency DC-DC converters requiring low switching loss and compact footprint.
For engineers reviewing the RS1JFL datasheet, RS1JFL pinout, RS1JFL application, or RS1JFL equivalent, key selection criteria include its 600 V repetitive peak reverse voltage, thermal resistance of 17 °C/W (junction-to-lead), moisture sensitivity level 1 compliance, and compatibility with automated SMT placement on standard PCB land patterns.
Technical Context
The RS1JFL employs a glass-passivated silicon die optimized for fast recovery in high-frequency switching topologies. Its 250 ns trr and 11 pF CJ enable reduced switching losses compared to general-purpose rectifiers, while the SOD-123FL package supports high-density board layouts with minimal thermal impedance.
Rated for 1 A average forward current and 30 A non-repetitive surge, the device operates across –55°C to +150°C junction temperature range. Its cathode-band polarity marking and matte tin-plated leads ensure reliable solderability per J-STD-002 and whisker resistance per JESD 201 Class 1A.

| trr | 250 ns - Enables efficient operation at switching frequencies up to ~500 kHz before reverse recovery losses dominate. |
| VF @ 1A/25°C | 1.04 V - Contributes ~1.04 W conduction loss per device at full load, critical for thermal budgeting in sealed enclosures. |
| RθJL | 17 °C/W - Allows direct thermal path to PCB copper, supporting >0.8 W dissipation with 13 °C rise above lead temperature. |
| CJ @ 4V | 11 pF - Minimizes capacitive coupling noise in high dv/dt gate-drive or snubber circuits adjacent to control ICs. |

FAQ
What is the maximum junction temperature rating for RS1JFL?
The RS1JFL has a maximum junction temperature (TJ MAX) of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet revision B2103. This allows operation in enclosed industrial environments where ambient temperatures reach 85°C, provided thermal design maintains junction temperature below 150°C. The RS1JFL's 17 °C/W junction-to-lead thermal resistance supports this rating when mounted on a 5 mm × 5 mm copper pad.
Does RS1JFL have moisture sensitivity level 1 (MSL-1) certification?
Yes, RS1JFL is rated MSL-1 per J-STD-020, meaning it can be stored indefinitely at ≤30°C/60% RH without baking prior to reflow soldering. This eliminates pre-reflow bake cycles in high-throughput SMT lines, reducing production cost and cycle time. The RS1JFL's matte tin-plated leads also comply with J-STD-002 for solderability assurance.
What is the reverse recovery time (trr) specification for RS1JFL?
The RS1JFL has a typical reverse recovery time (trr) of 250 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the electrical specifications table in the Taiwan Semiconductor datasheet. This value is confirmed for all RS1JFL units and distinguishes it from lower-voltage variants like RS1GFL (150 ns), making RS1JFL suitable for 200–500 kHz switching applications where moderate recovery speed suffices.
Is RS1JFL halogen-free and RoHS compliant?
Yes, RS1JFL meets both RoHS Directive 2011/65/EU and IEC 61249-2-21 halogen-free requirements. The molding compound contains no brominated flame retardants, and total bromine/chlorine content is below 900 ppm. This compliance is documented in Taiwan Semiconductor's material declarations and applies to all RS1JFL production lots shipped after version B2103.
What is the marking code printed on the RS1JFL device body?
The RS1JFL is marked with "RJF" on its top surface, as specified in the absolute maximum ratings table of the Taiwan Semiconductor datasheet. This three-character code uniquely identifies the 600 V variant within the RS1xFL family and is used for visual inspection and automated optical recognition during SMT assembly verification.
