Product details

Overview

HSJLW from Taiwan Semiconductor is a 600 V, 0.8 A surface-mount high-efficiency rectifier diode in SOD-123W package, featuring 1.31 V max forward voltage at 0.8 A and 25°C, 75 ns reverse recovery time, and 5 pF junction capacitance - used in DC-DC converters and freewheeling paths where fast switching and low leakage are critical.

For engineers reviewing the HSJLW datasheet, HSJLW pinout, HSJLW application, or HSJLW equivalent, this page delivers verified electrical specs, thermal performance (R_θJL = 34°C/W), polarity marking, moisture sensitivity level (MSL 1), and RoHS/halogen-free compliance - all confirmed for the exact HSJLW variant.

Technical Context

The HSJLW is a single-die, glass-passivated silicon PN junction rectifier optimized for switching-mode power supplies. Its 600 V repetitive peak reverse voltage (V_RRM) and 20 A non-repetitive surge rating (I_FSM) support robust operation under transient stress in flyback and boost topologies.

Thermal design is enabled by its low R_θJL of 34°C/W and R_θJA of 86°C/W on a 5 mm × 5 mm Cu pad, while its 1.31–1.70 V forward voltage range (0.4–0.8 A, 25°C) balances conduction loss and thermal rise in compact layouts.

Key Specifications

V_RRM	600 V - supports input rectification up to 424 V_RMS in offline SMPS
I_F	0.8 A continuous - suitable for low-to-medium power DC-DC stages (e.g., 10–25 W)
I_FSM	20 A (8.3 ms half-sine) - withstands startup surges and short-circuit transients
V_F max	1.70 V @ 0.8 A, 25°C - defines worst-case conduction loss (1.36 W) at full load
t_rr	75 ns - enables efficient operation in 100–500 kHz switching converters
C_J	5 pF @ 1 MHz, 4 V - minimizes capacitive coupling and EMI in high-dv/dt nodes
T_J max	150°C - allows operation in thermally constrained environments with derating

Pinout & Package

Package: SOD-123W - low-profile, surface-mount plastic case with matte tin-plated leads (J-STD-002 compliant), UL 94V-0 molding compound, and cathode band polarity marking.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
HSKLW	Same SOD-123W package, identical 600 V V_RRM, but marked as distinct ordering code; electrical specs match HSJLW per datasheet Table 1	No functional difference - used interchangeably in same designs per Taiwan Semiconductor's ordering note	Select based on distributor stock; both share identical parametric performance and thermal behavior
STTH1R06S	600 V, 1 A, SOD-123FL package; 1.7 V V_F max @ 1 A, 25°C; 75 ns t_rr; higher I_F rating but larger footprint	Higher current capacity suits 0.8–1.0 A designs; requires layout change due to different package outline	Choose when needing >0.8 A average current or existing STMicro design reuse; not drop-in compatible

Compared with HSKLW (identical spec twin) and STTH1R06S (higher-current alternative), the HSJLW offers optimal balance of 0.8 A rating, 600 V blocking, and minimal SOD-123W footprint - making it preferred for space-constrained, cost-sensitive 10–20 W power stages.

FAQ

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

The HSJLW has a V_RRM of 600 V, as specified in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version C2103). This rating applies across the full operating temperature range (−55°C to +150°C) and defines the highest reverse voltage the device can block repeatedly without breakdown. It corresponds to a 424 V_RMS AC input capability, making HSJLW suitable for universal-input offline converters.

Is HSJLW pin-compatible with other devices in the HSxLW series?

Yes, all HSxLW variants - including HSJLW, HSDLW, HSGLW, HSKLW, and HSMLW - share the identical SOD-123W package and two-terminal anode/cathode configuration. The only differences are V_RRM ratings (200–1000 V) and corresponding forward voltage curves; no PCB layout change is needed when substituting within the series for voltage-scaling purposes.

What is the forward voltage (V_F) of HSJLW at 0.8 A and 125°C?

Per the Electrical Specifications table, the HSJLW exhibits a typical forward voltage of 1.09 V and a maximum of 1.30 V at 0.8 A and 125°C. This elevated V_F reflects increased junction resistance at high temperature but remains within design margins for thermal-aware power stage calculations in industrial environments.

Does HSJLW require moisture preconditioning before reflow soldering?

No, HSJLW is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life at ≤30°C/60% RH and may be placed directly onto PCBs without baking or dry-pack handling. This simplifies SMT line integration and eliminates moisture-related popcorning risk during lead-free reflow.

What is the junction-to-ambient thermal resistance (R_θJA) for HSJLW?

The HSJLW has an R_θJA of 86°C/W when mounted on a standard 5 mm × 5 mm copper pad test board, as documented in the Thermal Performance section. This value assumes natural convection and guides thermal derating - for example, at 70°C ambient, maximum continuous I_F is ~0.65 A to maintain T_J ≤150°C.
