Product details

Overview

HS1JF-T from Taiwan Semiconductor is a 600 V, 1 A high-efficiency surface-mount silicon rectifier diode in SMAF package, featuring 75 ns reverse recovery time, 1.23 V forward voltage at 1 A/25°C, and 8 pF junction capacitance - optimized for freewheeling and DC-DC converter output stages.

For engineers reviewing the HS1JF-T datasheet, HS1JF-T pinout, HS1JF-T application, or HS1JF-T equivalent, key selection criteria include peak reverse voltage rating (600 V), thermal resistance (R_θJL = 15 °C/W), low leakage (<5 µA @ 25°C), and compatibility with automated SMT assembly on standard PCB pads.

Technical Context

The HS1JF-T is a single-die, glass-passivated PN junction rectifier designed for high-voltage switching power supplies. Its 600 V V_RRM, 30 A I_FSM (8.3 ms), and 150 °C maximum junction temperature support robust operation in transient-heavy environments.

With 75 ns reverse recovery time and 8 pF junction capacitance at 1 MHz/4 V, the HS1JF-T delivers fast switching performance while minimizing switching losses and EMI generation in high-frequency SMPS topologies.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1R06U	600 V V_RRM, 1 A I_F, 60 ns t_rr, TO-277 package (larger footprint, higher R_θJA)	Higher surge rating (50 A I_FSM) but requires larger PCB area and heatsinking	Preferred where surge robustness outweighs board space constraints
MBR160F	60 V V_RRM, Schottky architecture, 0.55 V V_F, 1 A I_F, SMAF package	Lower voltage rating precludes use in 400+ V systems; superior efficiency only below 100 V	Only suitable for low-voltage DC-DC outputs; not a functional substitute for HS1JF-T's 600 V capability

Compared with STTH1R06U, HS1JF-T offers identical voltage rating but smaller SMAF footprint and lower thermal resistance to lead (15 vs. ~25 °C/W); compared with MBR160F, HS1JF-T trades higher V_F for 10× higher V_RRM, making it the sole viable option for 600 V-class rectification.

FAQ

What is the maximum repetitive peak reverse voltage rating for HS1JF-T?

The HS1JF-T has a maximum repetitive peak reverse voltage (V_RRM) of 600 V, verified per Taiwan Semiconductor's B2103 datasheet revision. This rating defines the highest instantaneous reverse voltage the device can block repeatedly without breakdown under normal operating conditions. Designers must maintain ≥20% derating margin in systems with voltage transients or ringing. The HS1JF-T is part of the HS1DF-T to HS1MF-T family, where 'J' explicitly denotes the 600 V variant.

Does HS1JF-T support lead-free reflow soldering?

Yes, HS1JF-T supports lead-free reflow soldering. Its matte tin-plated leads comply with J-STD-002 for solderability, and the SMAF package is rated for peak reflow temperatures up to 260°C per JEDEC J-STD-020. The device is classified as Moisture Sensitivity Level 1 (MSL-1), meaning it can be stored indefinitely at ≤30°C/60% RH without baking prior to assembly. This makes HS1JF-T compatible with standard Pb-free manufacturing lines.

What is the typical forward voltage drop of HS1JF-T at 1 A and 125°C?

The typical forward voltage drop (V_F) of HS1JF-T at 1 A and 125°C is 1.02 V, with a maximum of 1.27 V, as specified in the Electrical Specifications table of the B2103 datasheet. This value is critical for thermal design at elevated ambient temperatures, as it directly impacts conduction loss (P_cond = I_F × V_F). At 125°C, V_F is ~17% lower than at 25°C (1.23 V), reflecting the negative temperature coefficient of silicon PN junctions.

How does the reverse recovery time of HS1JF-T compare to lower-voltage variants in the same family?

HS1JF-T has a maximum reverse recovery time (t_rr) of 75 ns, matching HS1KF-T and HS1MF-T, while HS1DF-T and HS1GF-T are rated at 50 ns. This difference reflects the trade-off between higher blocking voltage and minority carrier lifetime - the 600–1000 V variants use modified epitaxial layers that increase t_rr but enable higher V_RRM. For HS1JF-T, 75 ns remains suitable for switching frequencies up to 500 kHz in well-damped topologies.

Is HS1JF-T halogen-free and RoHS compliant?

Yes, HS1JF-T is both halogen-free and RoHS compliant. Taiwan Semiconductor confirms compliance with IEC 61249-2-21 for halogen-free materials and Directive 2011/65/EU (RoHS 2) for restricted substances. The molding compound contains no brominated flame retardants (BFRs), chlorinated flame retardants (CFRs), or antimony trioxide. These certifications are documented in the product's material declaration and are validated through third-party testing per the datasheet revision B2103.
