Product details

Overview

HS2BH from Taiwan Semiconductor is a 2 A, 100 V high-efficiency surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring low forward voltage (1.0 V @ 2 A), fast reverse recovery time (50 ns), and AEC-Q101 qualification for automotive use in DC-DC converters and freewheeling circuits.

For engineers reviewing the HS2BH datasheet, HS2BH pinout, HS2BH application, or HS2BH equivalent, key selection criteria include repetitive peak reverse voltage (100 V), surge current rating (50 A), junction-to-ambient thermal resistance (80 °C/W), and RoHS/halogen-free compliance for automotive-grade reliability.

Technical Context

This single-die, glass-passivated standard recovery rectifier operates with a maximum junction temperature of 150 °C and supports automated SMT placement. Its 50 ns reverse recovery time enables efficient switching in mid-frequency power conversion stages.

The device exhibits 5 µA max reverse leakage at 25 °C and 150 µA at 125 °C under rated VR, with typical junction capacitance of 50 pF at 1 MHz and 4 V reverse bias - characteristics optimized for snubber and freewheeling roles where low stored charge and predictable turn-off behavior are critical.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH2R010S	100 V V_RRM, 2 A I_F, 1.15 V V_F @ 2 A, 50 ns t_rr, DO-214AA	Slightly higher forward voltage increases conduction loss by ~150 mW at full load	Preferred where ST's qualification documentation aligns with OEM audit requirements

FAQ

What is the maximum junction temperature rating for HS2BH?

The HS2BH has a maximum junction temperature (T_J) rating of +150 °C, validated per its AEC-Q101 qualification. This allows reliable operation in under-hood automotive environments where ambient temperatures exceed 105 °C. Derating curves in the HS2BH datasheet define safe forward current limits above 75 °C ambient, ensuring thermal stability in real-world mounting conditions.

Is HS2BH suitable for use in synchronous rectification topologies?

No, HS2BH is a standard recovery rectifier diode and not designed for synchronous rectification. It lacks the gate control interface and low R_DS(on) required for active switching. HS2BH serves as a passive freewheeling or output rectifier in non-synchronous topologies like flyback or forward converters where its 50 ns t_rr and 1.0 V V_F provide optimal trade-offs between conduction and switching loss.

Does HS2BH have a halogen-free construction?

Yes, HS2BH is halogen-free in accordance with IEC 61249-2-21. The molding compound and internal materials meet this specification, supporting compliance with environmental directives in automotive and industrial end equipment. This is explicitly stated in the "Features" section of the official Taiwan Semiconductor HS2BH datasheet (Version A2102).

What is the marking code printed on the HS2BH device body?

The HS2BH device is marked with "HS2B" on its body, followed by date code and factory identifiers per the official marking diagram in the HS2BH datasheet. This two-character prefix distinguishes it within the HS2xH family and confirms its 100 V V_RRM rating - consistent with the ordering code HS2BH and mechanical outline DO-214AA (SMB).

How does HS2BH compare to HS2AH in terms of electrical performance?

HS2BH and HS2AH share identical package (DO-214AA), current ratings (2 A I_F, 50 A I_FSM), and thermal specs (150 °C T_J), but differ in V_RRM: HS2AH is rated for 50 V while HS2BH is rated for 100 V. Their forward voltage is identical (1.0 V @ 2 A), but HS2BH offers double the reverse blocking capability - making it suitable for 24 V and 48 V automotive systems where higher transient immunity is required.
