Product details
Overview
HS3FBH from Taiwan Semiconductor is a 3A, 300V repetitive peak reverse voltage (VRRM) surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring low forward voltage drop (1.0 V at 3 A, 25°C), fast reverse recovery time (50 ns), glass passivated junction, and AEC-Q101 qualification for automotive use.
For engineers reviewing the HS3FBH datasheet, HS3FBH pinout, HS3FBH application, or HS3FBH equivalent, key selection criteria include its 300V VRRM rating, 100A surge capability, 60°C/W junction-to-ambient thermal resistance, moisture sensitivity level 1 compliance, and suitability for DC-DC converters and freewheeling circuits requiring high efficiency and automated placement.
Technical Context
The HS3FBH is a single-die, standard recovery rectifier optimized for high-efficiency switching applications. Its 50 ns reverse recovery time and 1.0 V forward voltage at rated current support reduced conduction and switching losses in medium-voltage power conversion stages.
Designed with glass passivation and matte tin-plated leads compliant with J-STD-002, the device meets AEC-Q101 stress requirements and JESD201 Class 2 whisker resistance, enabling reliable operation in automotive ambient temperatures from –55°C to +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 300 V - Maximum non-repetitive reverse blocking voltage; defines safe operating limit in snubber or freewheeling paths |
| IF | 3 A - Continuous average forward current; determines steady-state power handling without derating below 75°C ambient |
| IFSM | 100 A - Peak surge current (8.3 ms half-sine); supports inrush and transient overload tolerance |
| VF @ 3A, 25°C | 1.0 V - Forward voltage drop; directly impacts conduction loss (P = IF × VF) in DC-DC output rectification |
| trr | 50 ns - Reverse recovery time; limits switching frequency ceiling and reduces turn-off switching loss |
| RθJA | 60 °C/W - Junction-to-ambient thermal resistance; used to calculate temperature rise under PCB-mounted conditions |
| TJ max | +150 °C - Maximum junction temperature; sets upper boundary for thermal design margin in enclosed automotive modules |
Pinout & Package
DO-214AA (SMB) package: surface-mount, low-profile plastic case with cathode band marking; dimensions per JEDEC DO-214AA outline; weight ≈ 0.093 g; UL 94V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-3EYH03-M3/54 | Same DO-214AA package, 300 V VRRM, but VF = 1.15 V @ 3 A; trr = 55 ns; not AEC-Q101 qualified | Lacks automotive qualification; suitable for industrial DC-DC but requires separate reliability validation for automotive deployment | Select when cost sensitivity outweighs AEC-Q101 requirement and thermal margin allows 0.15 V higher VF |
| ON Semiconductor MUR330 | DO-201AD package (larger), 300 V VRRM, VF = 1.1 V @ 3 A, trr = 50 ns, AEC-Q101 qualified | Through-hole mounting only; incompatible with automated SMT lines; requires PCB redesign and manual assembly | Select only if legacy through-hole infrastructure exists and DO-214AA footprint cannot be accommodated |
Compared with VS-3EYH03-M3/54 and MUR330, the HS3FBH uniquely combines AEC-Q101 qualification, DO-214AA SMT compatibility, and lowest VF (1.0 V) in its voltage class-enabling direct integration into automotive SMT power stages without derating or layout change.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) rating for HS3FBH?
The HS3FBH has a VRRM rating of 300 V, meaning it can reliably block up to 300 V of reverse voltage in repetitive applications without breakdown. This value is confirmed in the Absolute Maximum Ratings table of the official TSC datasheet Version A2102 and applies across the full operating temperature range of –55°C to +150°C. Exceeding this voltage risks irreversible avalanche failure.
Is HS3FBH qualified for automotive applications?
Yes, HS3FBH is explicitly AEC-Q101 qualified per the manufacturer's documentation. It undergoes stress testing including high-temperature reverse bias (HTRB), temperature cycling, and unbiased highly accelerated stress testing (uHAST) to meet automotive reliability standards. This qualification is stated in the FEATURES section of the TSC datasheet and verified in the product's certification records.
What is the forward voltage drop (VF) of HS3FBH at 3 A and 25°C?
The forward voltage drop of HS3FBH is 1.0 V at 3 A and 25°C, as specified in the Electrical Specifications table under "Forward voltage(1)" for the HS3FBH variant. This value is measured under pulsed conditions (PW = 0.3 ms) and represents typical conduction loss behavior in continuous-duty applications when properly heatsinked.
Does HS3FBH have a defined reverse recovery time (trr)?
Yes, HS3FBH has a reverse recovery time of 50 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter is documented in the Electrical Specifications table for the HS3FBH variant and confirms its suitability for medium-frequency switching applications up to ~500 kHz without excessive switching loss.
What package type does HS3FBH use, and is it compatible with standard SMT processes?
HS3FBH uses the DO-214AA (SMB) surface-mount package, with matte tin-plated leads solderable per J-STD-002 and moisture sensitivity level 1 per J-STD-020. Its low-profile design and L1 classification allow direct placement on reflow lines without baking, making it fully compatible with high-volume automated SMT assembly.
