Product details
Overview
S5BHE3_A/H from Vishay General Semiconductor is a surface-mount glass passivated rectifier diode rated for 5.0 A average forward current, 100 V maximum repetitive peak reverse voltage (VRRM), and 100 A non-repetitive surge current (IFSM), with 1.15 V forward voltage drop at 5.0 A - used in automotive-grade power supply rectification and freewheeling applications.
For engineers reviewing the S5BHE3_A/H datasheet, S5BHE3_A/H pinout, S5BHE3_A/H application, or S5BHE3_A/H equivalent, key selection criteria include AEC-Q101 qualification, DO-214AB (SMC) package compatibility, low leakage (10 µA at 25 °C), 2.5 µs reverse recovery time, and thermal resistance of 10 °C/W junction-to-lead.
Technical Context
This device is a single-junction, unidirectional silicon rectifier optimized for high-efficiency AC/DC conversion and inductive load switching. Its glass-passivated chip construction ensures stable performance across -55 °C to +175 °C operating junction temperature, while the matte tin-plated leads meet J-STD-002 solderability and JESD22-B102 whisker testing standards.
The S5BHE3_A/H belongs to the S5x family with fixed VRRM = 100 V (S5B variant), and shares mechanical dimensions, thermal characteristics, and AEC-Q101 qualification with other HE3-suffix parts. It is not a Schottky or fast recovery diode but a standard recovery rectifier with trr = 2.5 µs under defined test conditions (IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - defines maximum allowable reverse voltage before breakdown; critical for 12 V/24 V automotive system input stage protection |
| IF(AV) | 5.0 A at TL = 100 °C - continuous DC output capability with PCB copper pad thermal management |
| IFSM | 100 A (8.3 ms half-sine) - supports inrush current handling in switch-mode power supplies |
| VF | 1.15 V @ 5.0 A - determines conduction loss and thermal dissipation in rectifier stage |
| IR | 10 µA @ 25 °C - low leakage enables stable blocking in high-impedance circuits and battery backup paths |
| trr | 2.5 µs - limits switching losses and EMI generation during turn-off in flyback/freewheeling operation |
| TJ max. | +175 °C - enables operation in under-hood automotive environments without derating |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with UL 94 V-0 flammability rating; cathode indicated by color band; terminals are matte tin-plated, solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction | Connected to AC input or inductive load return path; must handle full IF(AV) and IFSM |
| Cathode | Current exit terminal during forward conduction; marked with color band | Connected to DC output rail or switching node; polarity-sensitive placement required on PCB |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements - enables use in engine control, body electronics, and ADAS power stages |
| Glass passivated junction | Enhanced moisture and contamination resistance vs. epoxy-passivated alternatives - improves long-term reliability in humid environments |
| Low profile SMC package | Height ≤ 2.62 mm - supports low-profile board stacking and automated pick-and-place with standard feeders |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without preconditioning - reduces manufacturing complexity |
| Junction-to-lead thermal resistance | RθJL = 10 °C/W - enables efficient heat transfer to PCB copper pads, supporting 5 A operation at TL = 100 °C |
Applications

IC Role / Device Role / Timing Role: Preventing backfeed between parallel power sources and enabling hot-swap capability. Use Value: Low VF (1.15 V) reduces conduction loss in high-current paths; SMC package supports high-density layout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS5H100SF | Schottky diode, VF ≈ 0.75 V @ 5 A, VRRM = 100 V, no trr specification, TJ max = 175 °C | Lower conduction loss but higher IR (≈ 1 mA @ 100 V); unsuitable where low leakage is critical | Select when efficiency > leakage sensitivity; verify thermal design due to lower VF but higher IR-induced leakage heating |
| ONsemi MUR5100E | Ultrafast recovery diode, VF = 1.7 V @ 5 A, trr = 75 ns, VRRM = 100 V, TJ max = 175 °C | Higher VF increases conduction loss; faster trr reduces EMI but requires tighter layout for ringing control | Select for high-frequency (>100 kHz) switching where fast recovery outweighs VF penalty; not AEC-Q101 qualified |
Compared with STPS5H100SF and MUR5100E, the S5BHE3_A/H offers balanced trade-offs: AEC-Q101 compliance for automotive use, moderate VF and trr, and industry-standard SMC footprint - making it optimal for cost-sensitive, thermally constrained, and qualification-driven designs.

FAQ
What is the maximum junction temperature rating for the S5BHE3_A/H?
The S5BHE3_A/H has a maximum junction temperature (TJ max.) of +175 °C, verified per the Vishay datasheet Document Number 88931. This rating allows reliable operation in under-hood automotive environments and high-ambient industrial settings. Derating curves in the datasheet define safe IF(AV) limits at elevated temperatures. The S5BHE3_A/H must be mounted on a PCB with appropriate copper pad area (0.3" x 0.3") to achieve thermal resistance of 10 °C/W and maintain this rating.
Is the S5BHE3_A/H AEC-Q101 qualified?
Yes, the S5BHE3_A/H is explicitly AEC-Q101 qualified, as confirmed in the Vishay datasheet revision 21-May-2024 (Document Number 88931). The "HE3" suffix denotes AEC-Q101 qualification, and the "_A/H" denotes packaging variant (7" tape and reel, 850 units). This qualification covers stress tests including temperature cycling, humidity bias, and high-temperature operating life - making the S5BHE3_A/H suitable for automotive power electronics such as body control modules and infotainment power supplies.
What does the "_A/H" suffix mean in S5BHE3_A/H?
The "_A/H" suffix in S5BHE3_A/H indicates the packaging configuration: "A" is the revision code (per Vishay's revision tracking), and "H" is the preferred package code denoting 7" diameter plastic tape and reel with 850 units per reel. This matches the ordering information table in the datasheet. The base part S5BHE3 is AEC-Q101 qualified; the suffix adds delivery mode and quantity details - not electrical or reliability differences. Other variants like S5BHE3_A/I use "I" for 13" reels (3500 units).
What is the reverse recovery time (trr) of the S5BHE3_A/H, and how is it measured?
The S5BHE3_A/H has a typical reverse recovery time (trr) of 2.5 µs, measured under the conditions specified in the Vishay datasheet: IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value reflects the time required for the diode to transition from forward conduction to reverse blocking. It is not a fast- or ultrafast-recovery diode, but its trr is sufficient for line-frequency and medium-frequency (<100 kHz) switching applications. Designers should verify snubber requirements based on actual circuit dV/dt and load inductance.
Does the S5BHE3_A/H have a RoHS-compliant and halogen-free version?
The S5BHE3_A/H is RoHS-compliant per the "HE3" suffix definition in the Vishay datasheet, but it is not halogen-free. Halogen-free versions use the "M3" suffix (e.g., S5B-M3). The "HE3" suffix guarantees RoHS compliance and AEC-Q101 qualification, while "M3" guarantees halogen-free, RoHS-compliant commercial grade. No single suffix combines both HE3 and M3 attributes. Therefore, S5BHE3_A/H meets RoHS but contains halogens - confirm material declaration (www.vishay.com/doc?99912) for full compliance reporting.
