Product details

Overview

HS1D from Taiwan Semiconductor is a high-efficiency surface-mount silicon rectifier diode rated for 200 V repetitive peak reverse voltage (V_RRM), 1 A average forward current (I_F), and 30 A non-repetitive surge current (I_FSM). It features fast recovery time (t_rr ≤ 50 ns), low forward voltage drop (V_F ≤ 1.0 V at 1 A, 25°C), and DO-214AC (SMA) package - used in DC/DC converters and snubber circuits.

For engineers reviewing the HS1D datasheet, HS1D pinout, HS1D application, or HS1D equivalent, key selection criteria include its 200 V V_RRM, 50 ns t_rr, 1.0 V V_F, thermal resistance (R_θJL = 15 °C/W), and DO-214AC mechanical compatibility with automated SMT assembly.

Technical Context

The HS1D is a single-die, glass-passivated, planar junction silicon rectifier optimized for high-frequency switching applications. Its fast recovery (≤50 ns) and low junction capacitance (20 pF at 1 MHz, 4 V) support efficient operation in SMPS and inverters where switching losses must be minimized.

Designed for surface-mount use on standard PCBs with 5 mm × 5 mm copper pads, the device meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1 - enabling reflow compatibility without baking. Polarity is marked by a cathode band per JEDEC DO-214AC outline.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - maximum repetitive reverse blocking voltage before breakdown; defines usable input voltage range in DC/DC stages.
I_F	1 A continuous - average forward current rating at 75°C case temperature; determines steady-state power handling capability.
t_rr	≤50 ns - reverse recovery time under I_F=0.5 A, I_R=1.0 A, I_rr=0.25 A; enables >100 kHz switching without excessive loss.
V_F	≤1.0 V at I_F=1 A, T_J=25°C - forward conduction loss directly impacts efficiency in high-current paths.
C_J	20 pF at 1 MHz, V_R=4 V - low junction capacitance minimizes capacitive switching loss and EMI generation.
R_θJL	15 °C/W - junction-to-lead thermal resistance; enables direct heat transfer to PCB copper, supporting compact layout.

Pinout & Package

Package: DO-214AC (SMA), molded plastic body per JEDEC DO-214 variation AC; cathode indicated by band; matte tin-plated leads compliant with J-STD-002 solderability.

Pin/Terminal	Circuit Role	Design Meaning

Cathode	Forward current exit / reverse blocking terminal	Marked by band; connects to higher-potential node; critical for polarity-sensitive snubber and freewheeling placement.

Key Features

Feature	Design Value

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1L06	V_RRM = 600 V, t_rr = 65 ns, V_F = 1.15 V @ 1 A	Higher voltage rating but slower recovery and higher V_F; suited for 400 V bus applications.	Select when system requires >200 V blocking margin and can tolerate ~15% higher conduction loss.
MBR120	Schottky structure, V_RRM = 200 V, V_F = 0.55 V @ 1 A, no reverse recovery	No t_rr or reverse leakage concerns; limited to ≤125°C operation due to leakage rise.	Prefer for low-noise, low-loss 25–100°C ambient applications where reverse leakage <1 µA is critical.

Compared with STTH1L06 and MBR120, the HS1D offers optimal balance of 200 V rating, 50 ns recovery, and 1.0 V V_F for cost-sensitive 100–200 V industrial converters requiring reliable thermal performance up to 150°C junction temperature.

FAQ

What is the maximum junction temperature rating for HS1D?

The HS1D has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings table. This allows operation in high-ambient industrial environments when mounted on a 5 mm × 5 mm copper pad. Derating curves confirm usable current down to 0.5 A at 125°C case temperature. Thermal design must account for R_θJL = 15 °C/W to ensure HS1D stays within spec under full load.

Does HS1D have a specified reverse recovery time, and how is it measured?

Yes, HS1D has a specified reverse recovery time (t_rr) of ≤50 ns, measured under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A per the electrical specifications table. This value is confirmed across the HS1A–HS1G group and reflects actual device behavior in high-frequency switching waveforms. The test circuit diagram is provided in Figure 10 of the official datasheet revision M2401.

Is HS1D RoHS compliant and halogen-free?

Yes, HS1D is RoHS compliant and halogen-free, as explicitly stated in the FEATURES section of the official documentation. The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated per J-STD-002. These attributes are verified for the DO-214AC (SMA) package variant shipped under ordering code HS1D.

What is the marking code printed on the HS1D device body?

The HS1D device is marked with "HS1D" on its molded plastic body, as confirmed in the ABSOLUTE MAXIMUM RATINGS table under "Marking code on the device". This marking appears adjacent to the cathode band and aligns with JEDEC DO-214AC orientation standards. No additional date or factory codes are required for identification of the base part number.

Can HS1D replace HS1B in an existing design without layout changes?

Yes, HS1D can replace HS1B without PCB layout changes because both share identical DO-214AC (SMA) package dimensions, pinout, and thermal pad requirements. However, HS1D's higher V_RRM (200 V vs. 100 V) and identical t_rr/V_F specs provide increased voltage margin while maintaining the same forward conduction and switching behavior - making HS1D a safe upgrade for 100–200 V applications.
