Product details
Overview
HS3MBH from Taiwan Semiconductor is a 1000 V repetitive peak reverse voltage, 3 A average forward current, surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring 1.7 V max forward voltage at 3 A and 75 ns reverse recovery time-used in automotive freewheeling and DC-DC converter snubber circuits.
For engineers reviewing the HS3MBH datasheet, HS3MBH pinout, HS3MBH application, or HS3MBH equivalent, key selection criteria include its AEC-Q101 qualification, 100 A surge rating, 150°C max junction temperature, low-profile SMB package, and verified performance under 100°C reverse bias conditions.
Technical Context
This high-voltage rectifier uses a single-die, glass-passivated PN junction optimized for fast switching and low conduction loss. Its 75 ns reverse recovery time and 50 pF junction capacitance at 4 V support efficient operation in high-frequency DC-DC topologies up to several hundred kHz.
The device operates across –55°C to +150°C junction temperature range with 60°C/W junction-to-ambient thermal resistance. It meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity requirements for automated SMT assembly.

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 | Same DO-214AA package; 1000 V VRRM; 1.85 V VF @ 3 A; 100 ns trr | Slightly higher VF increases conduction loss; longer trr may limit >300 kHz use | Prefer HS3MBH where <75 ns trr or <1.7 V VF is required for efficiency-critical designs |
| ON Semiconductor MUR3100CT | TO-220AB package; dual common-cathode; 1000 V; 1.75 V VF @ 3 A; 60 ns trr | Through-hole mounting; higher thermal mass but larger footprint; not AEC-Q101 qualified | Choose HS3MBH for SMT automotive designs requiring AEC-Q101 and space-constrained layouts |
Compared with VS-3EWH10-M3 and MUR3100CT, HS3MBH delivers superior combination of AEC-Q101 compliance, 75 ns trr, and 1.7 V VF in a low-profile SMB package-making it optimal for automotive SMT power stages where thermal, size, and qualification constraints converge.

FAQ
What is the maximum junction temperature rating for HS3MBH?
The HS3MBH has a maximum junction temperature (TJ) rating of +150°C, validated per JEDEC standards. This allows continuous operation at full 3 A forward current in ambient temperatures up to +125°C when mounted on appropriate PCB copper area. The 150°C TJ rating supports deployment in under-hood automotive environments and sealed industrial enclosures where thermal dissipation is constrained.
Is HS3MBH qualified for automotive applications?
Yes, HS3MBH is AEC-Q101 qualified, meaning it has passed stress tests including HTSL, TCT, UHAST, and ESD per the AEC-Q101-Rev-H standard. This qualification confirms suitability for automotive powertrain, chassis, and body electronics-including solenoid drivers, LED lighting, and DC-DC converters-where reliability under thermal cycling and vibration is critical.
What does the 'M' in HS3MBH signify?
The 'M' in HS3MBH denotes the 1000 V repetitive peak reverse voltage (VRRM) rating within the HS3x family. Per TSC's ordering nomenclature, 'A'=50 V, 'B'=100 V, 'D'=200 V, 'F'=300 V, 'G'=400 V, 'J'=600 V, 'K'=800 V, and 'M'=1000 V. Thus, HS3MBH is the highest-voltage variant in the HS3xBH series.
What is the reverse recovery time (trr) of HS3MBH and how is it measured?
The HS3MBH has a typical reverse recovery time (trr) of 75 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per JEDEC JESD28-C. This value reflects the time required for minority carriers to clear after forward conduction, directly impacting switching loss in high-frequency converters. The 75 ns trr enables stable operation in 100–500 kHz topologies.
Does HS3MBH have halogen-free and RoHS-compliant construction?
Yes, HS3MBH is both halogen-free per IEC 61249-2-21 and RoHS compliant per EU Directive 2011/65/EU. Its molding compound contains no brominated flame retardants, and its matte tin-plated leads meet J-STD-002 solderability requirements. These attributes support environmentally responsible manufacturing and end-of-life processing in global electronics supply chains.
