Product details
Overview
HS5BH from Taiwan Semiconductor is a 5A, 100V glass-passivated surface-mount rectifier in DO-214AB (SMC) package, featuring low forward voltage (1.00 V @ 5A, 25°C), 150A surge rating, and AEC-Q101 qualification for automotive reliability.
For engineers reviewing the HS5BH datasheet, HS5BH pinout, HS5BH application, or HS5BH equivalent, key selection criteria include reverse voltage rating (100 V), thermal resistance (60 °C/W), junction capacitance (80 pF), reverse recovery time (≤50 ns), and moisture sensitivity level (MSL 1).
Technical Context
The HS5BH is a single-die, unidirectional silicon rectifier optimized for high-efficiency DC/DC conversion and freewheeling paths where fast recovery and low conduction loss are critical. Its glass-passivated junction ensures stable operation under thermal cycling and humidity stress.
Designed for automated SMT assembly, it meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability standards. Polarity is marked by a cathode band, and terminals are matte tin-plated for reliable solderability per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse voltage; defines safe blocking capability in snubber or flyback clamp circuits |
| IF | 5 A - continuous average forward current; supports medium-power automotive lighting and DC/DC output stages |
| IFSM | 150 A - non-repetitive surge rating; handles inrush and transient overloads without failure |
| VF @ 5A, 25°C | 1.00 V - low conduction loss enabling >92% efficiency in 12V–48V converter outputs |
| trr | ≤50 ns - fast reverse recovery; minimizes switching losses in 100–500 kHz SMPS topologies |
| RθJA | 60 °C/W - thermal resistance from junction to ambient; requires minimal copper area for thermal management |
| MSL | Level 1 - unlimited floor life at ≤30°C/60% RH; no bake required before reflow |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, single-anode/single-cathode configuration with cathode band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (lead 1) | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck converter or ground return in freewheeling path) |
| Cathode (lead 2, banded end) | Forward current exit / reverse blocking terminal | Connected to higher-potential rail; blocks reverse current up to 100 V; polarity must be observed to prevent catastrophic failure |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade temperature cycling, mechanical shock, and humidity exposure per stress test requirements |
| Glass-passivated junction | Eliminates risk of junction corrosion and leakage drift in humid or chemically aggressive environments |
| Low VF (1.00 V @ 5A) | Reduces power dissipation by ≥0.5 W vs. standard 1.3 V rectifiers at same load, lowering heatsink demand |
| Fast trr (≤50 ns) | Enables clean turn-off in synchronous rectifier-assisted topologies and reduces EMI generation |
| DO-214AB footprint | Standardized SMC land pattern allows drop-in replacement across 5A rectifier families without PCB redesign |
Applications
| Automotive LED Lighting | DC/DC Converter Output Rectification |
|---|---|
Use Scenario: High-brightness LED headlamp modules requiring regulated 12–48 V supply with tight thermal constraints. IC Role / Device Role / Timing Role: Freewheeling diode in buck or boost converter output stage, conducting during low-side switch off-time. Use Value: Low VF and 150 A IFSM ensure stable current delivery during cold-crank transients; AEC-Q101 compliance guarantees field reliability. | Use Scenario: Secondary-side rectification in isolated 200–500 kHz flyback or forward converters for infotainment power supplies. IC Role / Device Role / Timing Role: Unidirectional current path that blocks reverse voltage while recovering rapidly between switching cycles. Use Value: 50 ns trr and 80 pF CJ minimize switching loss and capacitive coupling noise, improving efficiency and EMI margin. |
| Snubber Network Protection | Freewheeling in Solenoid Drivers |
Use Scenario: RCD snubber across MOSFETs in automotive body control modules handling inductive loads. IC Role / Device Role / Timing Role: Clamping diode that conducts only during voltage spikes, absorbing energy from leakage inductance. Use Value: 100 V VRRM safely clamps typical 60–85 V drain spikes; fast trr prevents delayed conduction that would degrade snubber effectiveness. | Use Scenario: Freewheeling path for 12 V solenoid valves in transmission control units. IC Role / Device Role / Timing Role: Provides low-impedance return path for inductive kickback when driver FET turns off. Use Value: 5 A IF rating matches typical solenoid hold current; glass passivation prevents degradation from under-hood condensation and thermal cycling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-5EWH01-M3/45 | Same DO-214AB package, 100 V VRRM, but VF = 1.15 V @ 5A; trr = 35 ns; not AEC-Q101 qualified | Suitable for industrial DC/DC but not automotive due to missing qualification | Select if faster recovery is prioritized and automotive qualification is unnecessary |
| ON Semiconductor MUR5100CT | TO-220AC package (not SMD); dual common-cathode die; VF = 1.2 V @ 5A; trr = 75 ns; AEC-Q101 not claimed | Requires through-hole mounting and larger board area; intended for higher-power discrete designs | Choose only when dual-diode topology or higher surge margin is needed and SMT is not mandatory |
Compared with VS-5EWH01-M3/45, HS5BH offers lower conduction loss and automotive qualification at the cost of slightly slower recovery; versus MUR5100CT, HS5BH enables compact SMT layout and better thermal performance per unit volume despite lower peak surge rating.

FAQ
What is the maximum junction temperature rating for HS5BH?
The HS5BH has a maximum junction temperature (TJ MAX) of +150°C, validated per AEC-Q101 stress testing. This rating allows operation in under-hood automotive environments where ambient temperatures reach 125°C, provided thermal design maintains junction temperature below 150°C using the specified RθJA of 60°C/W. Derating curves in the HS5BH datasheet confirm usable current capacity down to –55°C.
Is HS5BH suitable for use in automotive applications?
Yes, HS5BH is AEC-Q101 qualified and explicitly listed for automotive applications including car lighting and DC/DC converters. It passes temperature cycling, humidity bias, and mechanical shock tests required for automotive grade components. Its glass-passivated junction, MSL 1 rating, and matte tin-plated leads further support reliability in harsh vehicle environments.
What does the "HS5BH" marking code indicate on the device body?
The marking code "HS5B" on the HS5BH device identifies it as the 100 V variant within the HS5xH family (per ordering table). The "H" suffix denotes the DO-214AB (SMC) package. This marking is laser-etched on the cathode-band end and aligns with Taiwan Semiconductor's standardized coding system for voltage grade and package type.
How does the forward voltage of HS5BH compare across operating conditions?
The HS5BH specifies VF = 1.00 V maximum at IF = 5 A and TJ = 25°C. At elevated junction temperatures (e.g., 125°C), VF decreases slightly due to semiconductor physics, but the datasheet does not provide a full VF vs. TJ curve. Pulse testing (PW = 0.3 ms) ensures this value reflects realistic switching-conduction conditions, not DC-only measurement.
Can HS5BH replace HS5AH in a design?
HS5BH can replace HS5AH only if the circuit requires 100 V reverse blocking instead of 50 V - they share identical package, thermal, and surge ratings, but differ in VRRM (100 V vs. 50 V) and VF (1.00 V vs. unspecified for HS5AH at 5A). Substitution should be verified against worst-case reverse voltage stress and forward loss budget in the target application.
