Product details
Overview
HS3MB-K from Taiwan Semiconductor is a 1000 V repetitive peak reverse voltage, 3 A average forward current surface-mount silicon rectifier in DO-214AA (SMB) package, featuring 1.34 V typical forward voltage at 3.0 A and 25°C, 75 ns reverse recovery time, and 21 pF junction capacitance - used in high-efficiency DC/DC converters and switching inverters.
For engineers reviewing the HS3MB-K datasheet, HS3MB-K pinout, HS3MB-K application, or HS3MB-K equivalent, key selection criteria include its 1000 V VRRM, low leakage (<5 µA @ 25°C), thermal resistance (RθJL = 20°C/W), RoHS/halogen-free compliance, and suitability for automated SMT assembly in power conversion stages.
Technical Context
This device is a single-die, glass-passivated, standard recovery silicon rectifier optimized for high-voltage switching-mode power supplies. Its 1000 V VRRM rating and 80 A IFSM surge capability support robust operation under transient overloads in industrial inverters and freewheeling paths.
The HS3MB-K exhibits thermally stable forward voltage (0.75 V typ. @ 3 A, 125°C) and low junction capacitance (21 pF @ 1 MHz, 4 V), enabling efficient high-frequency rectification with minimal switching loss and EMI generation in compact PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| IF | 3 A continuous - delivers rated output current in SMB-footprint space-constrained converters |
| IFSM (8.3 ms) | 80 A - withstands inrush and short-circuit surges in SMPS primary-side rectification |
| VF @ 3 A, 25°C | 1.34 V typical - balances conduction loss and thermal rise in 12–48 V output DC/DC stages |
| trr | 75 ns - enables use up to ~500 kHz switching frequencies with controlled reverse recovery loss |
| CJ @ 1 MHz | 21 pF - reduces capacitive coupling and dv/dt-induced noise in high-speed gate-drive isolation circuits |
| RθJL | 20 °C/W - allows direct PCB copper pad heat sinking without external heatsink in ≤3 W dissipation designs |
Pinout & Package
DO-214AA (SMB) package: molded epoxy case with matte tin-plated leads, cathode band polarity marking, UL 94V-0 flammability rating, and JESD201 Class 1 whisker resistance.

| Cathode | Forward current exit / reverse blocking terminal | Marked by band; ties to positive rail or output capacitor in bridge or single-diode configurations |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-3EWH10-M3/45 | 1000 V VRRM, 3 A IF, but TO-277A package (smaller footprint, no leads); 1.45 V VF @ 3 A | Leadless design requires different stencil and reflow profile; higher VF increases conduction loss | Prefer when board space is critical and leaded SMB is not required |
| ON Semiconductor MUR3100CT | 1000 V VRRM, dual common-cathode die in TO-220AC; 1.75 V VF @ 3 A; faster trr (50 ns) | Through-hole mounting; higher VF and larger thermal mass limit high-frequency use | Prefer for legacy through-hole designs or where dual-diode integration simplifies layout |
Compared with VS-3EWH10-M3/45 and MUR3100CT, the HS3MB-K offers leaded SMB compatibility for automated placement, lower forward voltage than the MUR3100CT, and better thermal resistance than the leadless Vishay part - making it optimal for new SMT-based industrial power supplies requiring reliability and manufacturability.

FAQ
What is the maximum junction temperature rating for the HS3MB-K?
The HS3MB-K has a maximum junction temperature (TJMAX) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating allows reliable operation in enclosed industrial environments where ambient temperatures reach 85°C and power dissipation remains within thermal limits defined by RθJL = 20°C/W. Derating curves confirm usable current capacity down to 1.5 A at 125°C ambient.
Does the HS3MB-K have a specified reverse recovery time, and how does it compare to lower-voltage variants in the same family?
Yes, the HS3MB-K has a specified reverse recovery time (trr) of 75 ns under IF = 0.5 A, IR = 1.0 A, and IRR = 0.25 A test conditions. This is higher than the 50 ns trr of the HS3DB-K (200 V) due to higher voltage-rated epitaxial layer design, reflecting the inherent trade-off between VRRM and switching speed in standard recovery rectifiers.
Is the HS3MB-K compatible with lead-free reflow soldering processes?
Yes, the HS3MB-K features matte tin-plated leads qualified per J-STD-002 for solderability and is rated for moisture sensitivity level 1 (MSL-1) per J-STD-020 - meaning it can be stored indefinitely at ≤30°C/60% RH and withstand standard lead-free reflow profiles (peak 260°C) without baking. Its UL 94V-0 molding compound also ensures process stability.
What is the marking code printed on the HS3MB-K device body?
The HS3MB-K is marked with "HS3MB" on the device body, as confirmed in the Absolute Maximum Ratings table and Marking Diagram section of the Taiwan Semiconductor datasheet. The "-K" suffix denotes tape-and-reel packaging (3,000 units per reel) and is not part of the visible marking.
How does the junction-to-lead thermal resistance (RθJL) of the HS3MB-K impact PCB layout decisions?
The HS3MB-K's RθJL of 20°C/W means that for every watt of power dissipated, the junction rises 20°C above the lead temperature. To maximize thermal performance, designers must connect both anode and cathode pads to ≥10 mm × 10 mm internal or external copper planes - as validated in the thermal test condition - avoiding narrow traces or isolated pads that increase effective thermal resistance beyond specification.
