Product details

Overview

HS15GLW from Taiwan Semiconductor is a 1.5A, 400V glass-passivated surface-mount rectifier in SOD-123W package, optimized for high-efficiency DC/DC converters and switching-mode inverters with low forward voltage (0.93 V typ. @ 1.5A, 25°C) and fast reverse recovery (≤50 ns).

For engineers reviewing the HS15GLW datasheet, HS15GLW pinout, HS15GLW application, or HS15GLW equivalent, this device serves as a high-reliability, RoHS-compliant, halogen-free freewheeling diode requiring precise thermal management on PCBs with 5 mm × 5 mm copper pads and junction temperature monitoring up to +150°C.

Technical Context

The HS15GLW operates as a single-die, unidirectional silicon rectifier with cathode-band polarity indication and J-STD-020 Level 1 moisture sensitivity. Its 400 V repetitive peak reverse voltage (V_RRM) and 280 V RMS reverse voltage define its use in medium-voltage switching topologies.

Thermal performance is characterized by R_θJL = 43°C/W and R_θJA = 84°C/W on standard test board, supporting continuous 1.5 A conduction at ambient temperatures ≤70°C with adequate copper area. Junction capacitance is 22 pF at 1 MHz and 4.0 V reverse bias.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - Maximum repetitive reverse blocking voltage; sets upper limit for flyback snubber or output rectification in 24–48 V input systems.
I_F	1.5 A - Continuous average forward current; requires ≥5 mm × 5 mm Cu pad for thermal derating per datasheet curve.
V_F @ 1.5A, 25°C	0.93 V (typ), 1.30 V (max) - Directly impacts conduction loss and efficiency in high-frequency SMPS designs.
t_rr	≤50 ns - Enables operation in 100–500 kHz switching converters without excessive switching loss or EMI.
C_J @ 1 MHz, 4 V	22 pF - Low junction capacitance reduces capacitive coupling and improves high-frequency noise immunity.
I_R @ 400 V, 125°C	≤150 µA - Low leakage preserves efficiency in high-temperature environments such as enclosed power supplies.
R_θJA	84°C/W - Quantifies thermal resistance from junction to ambient; used to calculate max allowable power dissipation at given T_A.

Pinout & Package

Package: SOD-123W - Low-profile, surface-mount plastic case with matte tin-plated leads, UL 94V-0 molding compound, and cathode band marking. Weight: 0.016 g.

Pin/Terminal	Circuit Role	Design Meaning

Applications

DC/DC Converter Output Rectification	Switching Mode Inverter Freewheeling

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor MUR1540	Higher V_F (1.25 V max @ 1.5A), same V_RRM (400 V), TO-220AC package	Requires heatsink for >0.8 A; unsuitable for space-constrained SMT designs	Choose for higher surge robustness and legacy through-hole compatibility; avoid when SMT automation or low profile is required.
Vishay VS-1N5819HM3/85A	Lower V_RRM (40 V), Schottky architecture, 0.45 V V_F, SOD-123 package	Not rated for 400 V operation; limited to <60 V circuits	Choose only for low-voltage, ultra-low-loss applications; not a functional substitute for HS15GLW's 400 V capability.

Compared with MUR1540 and VS-1N5819HM3/85A, the HS15GLW uniquely balances 400 V blocking, 1.5 A SMT capability, and 0.93 V forward drop-making it optimal for modern compact, medium-voltage DC/DC and inverter designs where thermal and spatial constraints prohibit TO-220 or low-V_RRM solutions.

FAQ

What is the maximum junction temperature rating for HS15GLW?

The HS15GLW has a maximum junction temperature (T_J) of +150°C, verified per absolute maximum ratings table. This allows operation in high-ambient environments such as enclosed industrial power supplies, provided thermal design maintains junction temperature below this limit using the specified 5 mm × 5 mm copper pad and R_θJA = 84°C/W derating curve. The HS15GLW must not exceed +150°C at any point during operation.

Does HS15GLW support automated pick-and-place assembly?

Yes, the HS15GLW supports automated placement per its mechanical data: it uses a low-profile SOD-123W package with matte tin-plated leads compliant with J-STD-002 solderability standards and J-STD-020 Level 1 moisture sensitivity-eliminating pre-bake requirements. Its standardized tape-and-reel packaging (10,000 units per reel) is compatible with industry-standard SMT feeders, making HS15GLW suitable for high-volume manufacturing lines.

What is the reverse recovery time (t_rr) specification for HS15GLW?

The HS15GLW has a maximum reverse recovery time (t_rr) of 50 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions. This value is confirmed in the Electrical Specifications table and applies across the full operating temperature range. The fast t_rr enables efficient operation in switching frequencies up to 500 kHz, reducing switching losses and EMI generation compared to slower rectifiers in the same voltage class.

Is HS15GLW halogen-free and RoHS compliant?

Yes, the HS15GLW is both halogen-free per IEC 61249-2-21 and RoHS compliant, as explicitly stated in the FEATURES section of the official datasheet. These compliance attributes are verified for the entire HS15xLW family, including HS15GLW, and apply to all materials in the SOD-123W package-including molding compound, leadframe, and plating-ensuring suitability for export-controlled and environmentally regulated markets.

How does the forward voltage of HS15GLW vary with temperature?

The forward voltage of HS15GLW decreases with rising junction temperature: at 1.5 A, V_F drops from 0.93 V (typ) at 25°C to 0.79 V (typ) at 125°C. This negative temperature coefficient is confirmed in the Electrical Specifications table and supports stable current sharing in parallel configurations. Designers must account for this shift when calculating worst-case conduction loss at elevated temperatures, as the HS15GLW remains within spec across –55°C to +150°C TJ range.
