Product details
Overview
HS1DH from Taiwan Semiconductor is a 200V, 1A high-efficiency surface-mount rectifier diode with fast recovery (trr ≤ 50 ns), 1.0 V forward voltage at 1 A, and AEC-Q101 qualification for automotive-grade reliability. It uses a glass-passivated junction in DO-214AC (SMA) package and serves as a freewheeling or snubber diode in DC-DC converters.
For engineers reviewing the HS1DH datasheet, HS1DH pinout, HS1DH application, or HS1DH equivalent, key selection criteria include peak reverse voltage (200 V), thermal resistance (RθJL = 15 °C/W), junction capacitance (20 pF), and moisture sensitivity level (MSL 1).
Technical Context
The HS1DH is a single-die, unidirectional silicon rectifier optimized for high-frequency switching applications. Its fast recovery time (≤50 ns) and low forward voltage (1.0 V @ 1 A, 25°C) reduce conduction and switching losses in SMPS topologies.
Designed with glass passivation and matte tin-plated leads, it supports automated placement and meets JESD201 Class 2 whisker resistance and J-STD-020 MSL Level 1 requirements - enabling robust reflow compatibility without dry-pack handling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum repetitive reverse voltage; defines safe blocking capability in flyback or buck converter freewheel paths |
| IF | 1 A continuous - rated average forward current; determines thermal derating on PCB with 5 mm × 5 mm Cu pad |
| IFSM | 30 A (8.3 ms half-sine) - surge rating for startup or transient overload protection |
| VF | 1.0 V @ 1 A, 25°C - low conduction loss improves efficiency in high-duty-cycle DC-DC stages |
| trr | ≤50 ns - fast recovery minimizes reverse recovery charge (Qrr) and associated switching loss |
| CJ | 20 pF @ 1 MHz, 4 V - low junction capacitance reduces capacitive coupling noise in high-speed snubber networks |
| RθJL | 15 °C/W - low junction-to-lead thermal resistance enables direct heat transfer to PCB copper, simplifying thermal design |

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 MUR120 | VRRM = 200 V, trr = 75 ns, VF = 1.15 V @ 1 A - slower recovery and higher forward drop | Less suitable for >300 kHz designs due to higher Qrr; acceptable in cost-sensitive non-automotive SMPS | Choose when legacy footprint compatibility is required and switching frequency <250 kHz |
| Vishay VS-1EWH02-M3/5A | VRRM = 200 V, trr = 35 ns, VF = 1.05 V @ 1 A - faster recovery but not AEC-Q101 qualified | Lacks automotive qualification; requires additional reliability validation for automotive body control modules | Prefer for high-frequency industrial inverters where AEC-Q101 is not mandated |
Compared with MUR120 and VS-1EWH02-M3/5A, the HS1DH delivers optimal balance of automotive qualification, 50 ns recovery, and 1.0 V forward voltage - making it the preferred choice for space-constrained, thermally demanding automotive DC-DC and lighting systems.

FAQ
What is the peak repetitive reverse voltage rating for HS1DH?
The HS1DH has a peak repetitive reverse voltage (VRRM) rating of 200 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version B2401). It defines the maximum reverse-bias voltage the device can block continuously without breakdown, making HS1DH suitable for 24 V and 48 V automotive bus-derived DC-DC stages where transient clamping margins require ≥2× nominal voltage.
Is HS1DH qualified for automotive applications?
Yes, HS1DH is AEC-Q101 qualified per the manufacturer's documentation. This qualification covers stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and unbiased highly accelerated stress test (UHAST). The qualification applies directly to the HS1DH variant - not just the HS1xH family generically - and supports use in automotive body electronics, infotainment power supplies, and LED lighting modules.
What is the forward voltage of HS1DH at 1 A and 25°C?
The forward voltage (VF) of HS1DH is 1.0 V at IF = 1 A and TJ = 25°C, as specified in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and represents typical conduction loss. At elevated junction temperatures (e.g., 125°C), VF decreases slightly due to negative temperature coefficient of silicon diodes, remaining within 0.92–0.95 V range.
Does HS1DH have a defined moisture sensitivity level (MSL)?
Yes, HS1DH has a moisture sensitivity level (MSL) of Level 1 per J-STD-020. This means it may be stored indefinitely at ambient conditions (<30°C / 60% RH) and subjected to standard lead-free reflow profiles without baking. The MSL Level 1 rating is explicitly stated in the Features section and verified in the Mechanical Data section of the Taiwan Semiconductor datasheet.
What package type does HS1DH use, and what are its key mechanical features?
HS1DH uses the DO-214AC (SMA) surface-mount package. Key mechanical features include a 5 mm × 5 mm copper pad thermal interface, matte tin-plated leads compliant with J-STD-002 solderability, polarity indicated by cathode band, and UL 94V-0 rated molding compound. The package outline dimensions match JEDEC DO-214AC Variation AC, Issue D, with total weight ≈ 0.060 g.
