Product details
Overview
HS1BL from Taiwan Semiconductor is a 1A, 100V high-efficiency surface-mount silicon rectifier diode in Sub SMA package, featuring 0.95V forward voltage at 1A/25°C, 30A peak surge current, and 5µA reverse leakage at 25°C - used in DC-DC converters and switching-mode power supplies.
For engineers reviewing the HS1BL datasheet, HS1BL pinout, HS1BL application, or HS1BL equivalent, key selection criteria include repetitive peak reverse voltage (100 V), thermal resistance (100 °C/W), junction capacitance (20 pF), reverse recovery time (50 ns), and moisture sensitivity level (MSL 1).
Technical Context
The HS1BL is a single-die, glass-passivated, planar junction silicon rectifier optimized for high-frequency switching applications. Its low VF and fast trr enable reduced conduction and switching losses in compact power converters.
Designed for automated SMT placement, it meets JESD201 Class 1A whisker resistance and UL 94V-0 flammability standards. Polarity is marked by a cathode band on the Sub SMA case, with matte tin-plated leads compliant to J-STD-002 solderability.
Key Specifications

|---|---|
| VRRM | 100 V - maximum repetitive reverse voltage the device blocks reliably in circuit |
| IF | 1 A - continuous average forward current rating at TA = 25°C |
| VF @ 1A, 25°C | 0.95 V - forward voltage drop determining conduction loss in power path |
| IFSM | 30 A - non-repetitive surge current handling capability during startup or fault |
| trr | 50 ns - reverse recovery time affecting switching loss and EMI in high-frequency SMPS |
| RθJA | 100 °C/W - junction-to-ambient thermal resistance under standard PCB layout conditions |
| IR @ 100V, 25°C | 5 µA - reverse leakage current defining off-state power loss and isolation integrity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R04 | 1A, 400V VRRM; VF = 1.15V @ 1A; trr = 35ns; DO-214AC package | Higher voltage rating but higher VF and faster trr - better for 400V systems with tighter timing constraints | Select when 400V blocking is required and lower trr outweighs VF penalty |
| MBR1100 | 1A, 100V VRRM; Schottky; VF = 0.75V @ 1A; no trr; TO-277 package | Lower VF and zero reverse recovery, but limited to ≤100°C TJ and higher IR at elevated temperature | Prefer for low-loss, low-noise 100V applications below 125°C ambient |
Compared with STTH1R04 and MBR1100, the HS1BL offers balanced performance for 100V general-purpose rectification: lower VF than STTH1R04, superior high-temperature IR stability versus MBR1100, and MSL 1 suitability for high-volume SMT production.

FAQ
What is the maximum junction temperature rating for HS1BL?
The HS1BL has a maximum junction temperature (TJ MAX) of +150°C, enabling operation in demanding thermal environments such as enclosed power supplies and industrial motor controls. This rating is validated across its full voltage range (50–1000V variants) and supports derating curves up to 150°C ambient with appropriate PCB copper area. The HS1BL maintains specified electrical parameters within this range when mounted per recommended pad layout.
Does HS1BL have a defined moisture sensitivity level (MSL)?
Yes, the HS1BL is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and can be subjected to standard reflow profiles without pre-baking. This is confirmed in the official Taiwan Semiconductor datasheet Version C2103 and applies to all HS1xL series parts in Sub SMA packaging. The MSL 1 rating simplifies SMT line integration and eliminates dry-pack handling for HS1BL.
What is the reverse recovery time (trr) specification for HS1BL?
The HS1BL has a maximum reverse recovery time (trr) of 50 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is measured per JEDEC standards and reflects the device's suitability for high-frequency switching applications up to ~500 kHz. The HS1BL's trr is identical to HS1AL, HS1DL, and HS1FL - confirming consistent fast-recovery behavior across the lower-voltage variants of the family.
How does the forward voltage (VF) of HS1BL compare to other HS1xL variants?
The HS1BL has a typical forward voltage of 0.95 V at 1 A and 25°C - matching HS1AL and HS1DL, and lower than HS1GL (1.30 V) and HS1ML (1.70 V). This stepwise VF increase correlates directly with higher VRRM ratings due to thicker epitaxial layers. For 100V applications, the HS1BL delivers optimal balance of low conduction loss and sufficient voltage margin.
Is HS1BL halogen-free and RoHS compliant?
Yes, the HS1BL uses halogen-free molding compound per IEC 61249-2-21 and is fully RoHS compliant. These environmental qualifications are explicitly stated in the Taiwan Semiconductor HS1AL–HS1ML datasheet (Version C2103) and verified through material declarations. The halogen-free status ensures compatibility with stringent regional regulations without sacrificing UL 94V-0 flammability performance.
