Product details

Overview

HS2JFS from Taiwan Semiconductor is a 2 A, 600 V fast recovery surface-mount rectifier in SOD-128 package, featuring 1.10 V forward voltage at 2.0 A and 25°C, 75 ns reverse recovery time, and 17 pF junction capacitance - optimized for high-efficiency DC/DC converters and freewheeling paths in switching power supplies.

For engineers reviewing the HS2JFS datasheet, HS2JFS pinout, HS2JFS application, or HS2JFS equivalent, key selection criteria include its 600 V repetitive peak reverse voltage, thermal resistance (R_θJL = 17 °C/W), moisture sensitivity level 1 rating, RoHS/halogen-free compliance, and SOD-128 low-profile footprint compatibility with automated PCB assembly.

Technical Context

The HS2JFS employs a glass-passivated silicon die to achieve fast recovery (t_rr ≤ 75 ns) and stable reverse leakage (< 1 µA at 25°C, < 80 µA at 125°C) across its 600 V V_RRM rating. Its single-die configuration and SOD-128 package support high-current handling (I_F = 2 A continuous, I_FSM = 60 A @ 8.3 ms) with minimal thermal impedance to lead (17 °C/W).

Designed for operation from –55°C to +150°C junction temperature, the HS2JFS delivers predictable forward voltage drop (1.00 V typ. @ 1.0 A, 25°C; 0.92 V typ. @ 2.0 A, 125°C) and low junction capacitance (17 pF @ 1 MHz, 4 V), enabling efficient high-frequency switching in SMPS and inverters without excessive switching loss or ringing.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - supports input stages up to 420 V DC bus or 300 V AC rectification with safety margin
I_F	2 A continuous - sustains steady-state current in compact DC/DC output rectification
t_rr	75 ns max - enables operation up to ~2 MHz switching frequency with controlled turn-off loss
V_F	1.10 V max @ 2.0 A, 25°C - limits conduction loss to ≤2.2 W at full load, easing thermal design
C_J	17 pF @ 1 MHz, 4 V - reduces capacitive coupling and EMI in high-dV/dt node placement
R_θJL	17 °C/W - allows direct heat transfer to PCB copper, supporting >1.5 W dissipation on 5 mm × 5 mm pad
MSL	Level 1 (per J-STD-020) - no bake required before reflow, compatible with standard SMT lines

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH2R06S	600 V, 2 A, t_rr = 65 ns, VF = 1.15 V @ 2 A, SOD-128	Slightly faster recovery but higher V_F; identical package and thermal performance	Prefer when minimizing turn-off loss dominates over conduction loss
ES2J	600 V, 2 A, t_rr = 75 ns, V_F = 1.7 V @ 2 A, DO-214AA	Same speed, higher V_F, larger DO-214AA package requiring more board area	Select only if legacy DO-214AA layout exists and thermal margin permits higher loss

Compared with STTH2R06S and ES2J, the HS2JFS offers the lowest forward voltage among SOD-128 600 V rectifiers, delivering superior conduction efficiency in thermally constrained layouts while maintaining identical recovery speed to ES2J and matching STTH2R06S's package compatibility.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for HS2JFS?

The HS2JFS has a maximum repetitive peak reverse voltage (V_RRM) of 600 V, verified per Taiwan Semiconductor's C2103 datasheet revision. This rating defines the highest instantaneous reverse voltage the device can block repeatedly without breakdown, making HS2JFS suitable for 400 V DC bus applications with adequate safety margin. It is not interchangeable with HS2DFS (200 V) or HS2MFS (1000 V) without circuit revalidation.

What is the forward voltage (V_F) of HS2JFS at 2.0 A and 25°C?

The forward voltage (V_F) of HS2JFS is 1.10 V maximum at 2.0 A and 25°C, with a typical value of 1.10 V. This parameter is measured under pulsed conditions (PW = 0.3 ms) and directly impacts conduction loss - for example, resulting in ≤2.2 W dissipation at full rated current. At 125°C, V_F drops to 0.92 V typical, improving thermal stability in high-ambient designs.

Does HS2JFS have a specified reverse recovery time (t_rr)?

Yes, HS2JFS has a specified reverse recovery time (t_rr) of 75 ns maximum, tested at I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This value is confirmed in the Electrical Specifications table of the official datasheet and distinguishes HS2JFS from slower rectifiers like general-purpose 1N4007 (μs-range t_rr). It enables reliable operation in 100–500 kHz switching power supplies.

What package type does HS2JFS use, and what are its key mechanical features?

HS2JFS uses the SOD-128 surface-mount package, characterized by low profile (<0.9 mm height), matte tin-plated leads compliant with J-STD-002 solderability, UL 94V-0 flammability-rated molding compound, and moisture sensitivity level 1 (MSL-1). Polarity is marked by a cathode band, and the device weighs approximately 0.028 g - all confirmed in the Mechanical Data and Package Outline sections of the Taiwan Semiconductor datasheet.

Is HS2JFS RoHS and halogen-free compliant?

Yes, HS2JFS is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. This compliance applies to all materials in the SOD-128 package, including molding compound and lead finish, and is verified for production lots meeting revision C2103. No exemptions or exceptions are noted for this part number.
