Product details
Overview
SE10PBHM3/85A from Vishay General Semiconductor is an AEC-Q101-qualified surface-mount silicon rectifier diode in SMP (DO-220AA) package, rated for 100 V repetitive peak reverse voltage, 1.0 A average forward current, and 25 A non-repetitive surge current. It delivers low forward voltage drop (0.86 V at 1.0 A, 125 °C), <5 μA reverse leakage at rated VR, and ESD immunity exceeding 8 kV per HBM (AEC-Q101-001, JESD22-A114) - used for polarity and rail-to-rail protection in automotive power rails.
For engineers reviewing the SE10PBHM3/85A datasheet, SE10PBHM3/85A pinout, SE10PBHM3/85A application, or SE10PBHM3/85A equivalent, key selection criteria include its automotive-grade MSL-1 qualification, 175 °C max junction temperature, 7.0 pF junction capacitance at 4.0 V, and SMP package compatibility with high-density automated assembly.
Technical Context
This device is a single-die, oxide planar junction silicon rectifier optimized for low-profile (<1.0 mm height), high-reliability DC line protection. Its thermal resistance of 25 °C/W (junction-to-lead) and 105 °C/W (junction-to-ambient) supports sustained operation under automotive ambient conditions up to 125 °C.
The SE10PBHM3/85A features fast recovery (780 ns typical trr), low IR drift over temperature (≤50 μA at 125 °C), and robust ESD performance per IEC 61000-4-2 (≥15 kV air discharge). Its cathode-band-marked SMP package enables unambiguous orientation during pick-and-place and reflow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum reverse voltage the diode blocks continuously without breakdown; defines safe operating margin for 12 V/24 V automotive systems. |
| IF(AV) | 1.0 A - continuous DC forward current rating at TA = 75 °C on PCB with 5.0 mm × 5.0 mm copper pad; sets usable current capacity in power supply inputs. |
| VF @ 1.0 A, 125 °C | 0.86 V - forward voltage under hot, loaded conditions; directly determines conduction loss (0.86 W per diode at 1 A). |
| IR @ VR, 25 °C | ≤5.0 μA - maximum reverse leakage at rated voltage and room temperature; critical for low-power standby circuits and battery drain control. |
| trr | 780 ns - typical reverse recovery time; limits switching frequency suitability and minimizes commutation loss in flyback or clamp circuits. |
| CJ @ 4.0 V, 1 MHz | 7.0 pF - junction capacitance affecting high-frequency noise coupling and EMI filter design in DC input stages. |
| TJ max. | 175 °C - maximum allowable junction temperature; enables operation in under-hood environments with minimal derating. |
Pinout & Package
Package: SMP (DO-220AA), halogen-free, RoHS-compliant, automotive grade (HM3 suffix), 1.0 mm typical height, matte tin-plated leads, MSL level 1 (260 °C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry terminal | Connected to positive side of protected line; polarity must match schematic symbol to prevent reverse conduction failure. |
| Cathode (marked by band) | Forward current exit / reverse blocking terminal | Must be routed to system ground or lower-potential rail; band orientation ensures correct placement in automated assembly. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and body electronics; includes stress testing per human-body and machine-model ESD standards. |
| Low profile (1.0 mm height) | Enables use in space-constrained modules such as ADAS camera housings and compact ECUs where Z-height is limited. |
| MSL Level 1 rating | Allows unlimited floor life and standard 260 °C lead-free reflow without baking; eliminates moisture sensitivity handling overhead. |
| Oxide planar junction | Provides stable reverse leakage and predictable forward characteristics across temperature; improves long-term reliability vs. diffused junctions. |
| Junction capacitance (7.0 pF) | Minimizes capacitive coupling of transients into sensitive analog or communication lines downstream of protection stage. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Input Protection |
|---|---|

IC Role / Device Role / Timing Role: Series rectifier placed before buck converter to block reverse current and prevent backfeed into source. Use Value: 0.86 V VF at 1.0 A and 125 °C reduces heat generation in sealed enclosures; SMP footprint saves board area vs. SMA. |
Use Scenario: Input protection on -48 V telecom power feeds entering remote radio units (RRUs). IC Role / Device Role / Timing Role: High-reliability blocking diode in redundant power OR-ing configuration with hot-swap controllers. Use Value: 100 V VRRM provides 2× safety margin over nominal -48 V; AEC-Q101 qualification ensures extended field lifetime in outdoor cabinets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SE10PB-M3/85A | Commercial-grade (M3) version; same electrical specs but not AEC-Q101 qualified; JESD201 whisker test Class 1A vs. HM3's Class 2. | Limited to non-automotive industrial or consumer use; unsuitable for under-hood or safety-critical vehicle subsystems. | Select SE10PBHM3/85A when automotive qualification, higher whisker resistance, or extended temperature validation is required. |
| SB1040-TB-E3 | Same VRRM (100 V), IF(AV) (1.0 A), and DO-220AA package; VF slightly higher (0.95 V typ. @ 1 A); no AEC-Q101 or IEC 61000-4-2 data published. | Used in cost-sensitive industrial power supplies; lacks documented ESD immunity and automotive stress validation. | Choose SE10PBHM3/85A for designs requiring verified ESD robustness, automotive qualification, or guaranteed 175 °C operation. |
Compared with SE10PB-M3/85A and SB1040-TB-E3, the SE10PBHM3/85A uniquely combines AEC-Q101 qualification, >15 kV air-discharge ESD immunity, and 175 °C junction rating - making it the only option among the three validated for harsh automotive environments with transient-heavy power rails.

FAQ
What is the maximum junction temperature rating for the SE10PBHM3/85A?
The SE10PBHM3/85A has a maximum junction temperature (TJ max.) of 175 °C, enabling reliable operation in under-hood automotive environments and high-ambient industrial settings. This rating is validated per AEC-Q101 stress testing and supported by its thermal resistance values (RθJL = 25 °C/W, RθJA = 105 °C/W). The SE10PBHM3/85A maintains specified electrical performance up to this limit when mounted on a PCB with 5.0 mm × 5.0 mm copper pads.
Does the SE10PBHM3/85A meet automotive qualification standards?
Yes, the SE10PBHM3/85A is fully AEC-Q101 qualified per the Vishay document 89024 revision 16-Jun-2023. It passes human-body model (HBM) ESD testing to >8 kV (AEC-Q101-001, JESD22-A114), machine model (MM) to >400 V, and IEC 61000-4-2 air-discharge to >15 kV. Its HM3 suffix confirms automotive-grade material, whisker resistance (JESD201 Class 2), and MSL Level 1 reflow compatibility - all verified for SE10PBHM3/85A.
What is the forward voltage drop of the SE10PBHM3/85A at elevated temperature?
The SE10PBHM3/85A exhibits a typical forward voltage (VF) of 0.86 V at IF = 1.0 A and TA = 125 °C, with a maximum of 0.95 V under those conditions. This low, thermally stable VF minimizes conduction losses in high-temperature applications such as engine control units. The SE10PBHM3/85A datasheet specifies this value explicitly in the Electrical Characteristics table, confirming its suitability for thermally demanding deployments.
Is the SE10PBHM3/85A compatible with lead-free reflow processes?
Yes, the SE10PBHM3/85A is rated for MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C - fully compliant with standard lead-free soldering profiles. Its matte tin-plated terminals meet J-STD-002 and JESD 22-B102 solderability requirements, and the HM3 suffix confirms automotive-grade process validation. No pre-baking is required prior to reflow, simplifying manufacturing for the SE10PBHM3/85A.
What package type does the SE10PBHM3/85A use, and what are its key mechanical features?
The SE10PBHM3/85A uses the SMP (DO-220AA) surface-mount package: 1.0 mm typical height, 3.61 mm × 2.18 mm outline, cathode band marking, and matte tin-plated leads. Its ultra-low profile supports high-density layouts in compact modules, while the UL 94 V-0 molding compound ensures flame resistance. The SE10PBHM3/85A package dimensions and mounting pad layout are fully specified in the Vishay document 89024, Figure "PACKAGE OUTLINE DIMENSIONS".
