Product details
Overview
SE10PDHM3/85A from Vishay General Semiconductor is an AEC-Q101-qualified surface-mount ESD-capable silicon rectifier in SMP (DO-220AA) package, rated for 200 V repetitive peak reverse voltage (VRRM), 1.0 A average forward current (IF(AV)), and 25 A non-repetitive surge current (IFSM). It delivers low forward voltage drop (VF = 0.86 V at IF = 1.0 A, TJ = 125 °C) and ultra-low reverse leakage (IR ≤ 5 μA at rated VR, TA = 25 °C), enabling efficient rail-to-rail protection in automotive power line polarity circuits.
For engineers reviewing the SE10PDHM3/85A datasheet, SE10PDHM3/85A pinout, SE10PDHM3/85A application, or SE10PDHM3/85A equivalent, key selection criteria include its MSL Level 1 moisture sensitivity, JESD201 Class 2 whisker resistance, 175 °C maximum junction temperature, and verified ESD immunity per AEC-Q101-001 (>8 kV HBM), IEC 61000-4-2 (>15 kV air discharge), and JESD22-A114.
Technical Context
The SE10PDHM3/85A is a single-diode, oxide planar junction rectifier optimized for high-reliability automotive applications. Its thermal design supports RθJL = 25 °C/W and RθJC = 30 °C/W when mounted on PCB with 5.0 mm × 5.0 mm copper pads, enabling stable operation up to TJ = 175 °C under sustained 1.0 A load.
It exhibits fast recovery behavior (trr = 780 ns typical at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A) and low junction capacitance (CJ = 7.0 pF at 4.0 V, 1 MHz), making it suitable for moderate-speed switching and ESD-critical signal/power rail clamping where low stored charge and minimal capacitive loading are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse voltage the device blocks without breakdown; defines safe operating range for 24 V automotive systems with transients. |
| IF(AV) | 1.0 A - Continuous DC forward current rating at TA = 25 °C with derating above 25 °C; supports typical power-line protection loads. |
| VF @ IF = 1.0 A, TJ = 125 °C | 0.86 V - Low conduction loss ensures minimal power dissipation and thermal rise in compact automotive PCB layouts. |
| IR @ VR = 200 V, TA = 25 °C | ≤ 5.0 μA - Ultra-low leakage preserves system standby power integrity and prevents false triggering in high-impedance sensing nodes. |
| trr | 780 ns - Fast reverse recovery time limits switching losses and minimizes voltage overshoot during transient suppression events. |
| CJ @ 4.0 V, 1 MHz | 7.0 pF - Low junction capacitance avoids signal distortion and maintains bandwidth in ESD protection paths near high-speed interfaces. |
| TJ max. | 175 °C - Extended junction temperature rating enables reliable operation in under-hood and engine-control module environments. |
Pinout & Package
Package: SMP (DO-220AA) - ultra-low-profile surface-mount package with 1.0 mm typical height, matte tin-plated leads, and UL 94 V-0 molding compound. Cathode identified by band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry terminal | Connected to positive supply or protected line side; must withstand 25 A surge without bond wire failure. |
| Cathode | Forward current exit / reverse blocking terminal | Marked with band; serves as reference node for ESD clamp path and thermal measurement point (RθJL defined at cathode band). |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including HBM >8 kV, MM >400 V, and temperature cycling across -55 °C to +175 °C. |

| MSL Level 1 (J-STD-020) | Unlimited floor life at ≤30 °C/85 % RH - eliminates bake requirements before reflow, reducing manufacturing cost and risk. |
| JESD201 Class 2 whisker resistance | Qualified for automotive under-hood use where long-term tin whisker growth could cause latent short-circuit failures. |
| Oxide planar chip junction | Provides consistent reverse leakage and robust surge performance vs. diffused-junction alternatives, critical for production yield stability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SE10PBHM3/85A | VRRM = 100 V (vs. 200 V); identical package, thermal, and ESD specs. | Suitable only for 12 V nominal systems with lower transient margins; not rated for 24 V automotive architectures. | Select when system max reverse voltage ≤100 V and cost optimization is prioritized over margin. |
| SE10PGHM3/85A | VRRM = 400 V (vs. 200 V); same IF(AV), trr, CJ, and AEC-Q101 qualification. | Supports higher-voltage industrial SMPS inputs and 48 V mild-hybrid vehicle subsystems. | Choose for future-proofing or designs requiring ≥300 V reverse standoff with no layout change. |
Compared with SE10PBHM3/85A and SE10PGHM3/85A, the SE10PDHM3/85A provides optimal balance of 200 V reverse capability, low VF, and automotive qualification-making it the preferred choice for 24 V commercial vehicle electronics where 100 V is insufficient and 400 V adds unnecessary cost and capacitance.

FAQ
What is the maximum junction temperature rating for the SE10PDHM3/85A?
The SE10PDHM3/85A has a maximum junction temperature (TJ max.) of 175 °C, validated per AEC-Q101 stress testing. This rating allows continuous operation in under-hood automotive environments and high-ambient industrial settings. Derating curves in the datasheet show usable IF(AV) down to ~0.6 A at 125 °C ambient, ensuring thermal safety margins in sealed enclosures where airflow is limited. The SE10PDHM3/85A's RθJL = 25 °C/W further supports this rating when mounted on standard 5.0 mm × 5.0 mm copper pads.
Does the SE10PDHM3/85A meet automotive qualification standards?
Yes, the SE10PDHM3/85A is fully AEC-Q101 qualified, including human body model (HBM) ESD >8 kV per AEC-Q101-001 and JESD22-A114, machine model (MM) >400 V per AEC-Q101-002 and JESD22-A115, and IEC 61000-4-2 air-discharge >15 kV. Its HM3 suffix confirms automotive-grade material content, JESD201 Class 2 whisker resistance, and MSL Level 1 handling-making the SE10PDHM3/85A suitable for engine control units, ADAS modules, and other mission-critical automotive subsystems.
What does the "85A" suffix indicate in SE10PDHM3/85A?
The "85A" suffix in SE10PDHM3/85A specifies the packaging configuration: 13-inch diameter plastic tape and reel, with a base quantity of 10,000 units per reel. This differs from the "84A" variant, which uses 7-inch reels with 3,000 units. Both share identical electrical, thermal, and qualification characteristics-the "85A" designation solely reflects logistics and assembly-line feed compatibility for high-volume SMT lines using larger reels.
How does the SE10PDHM3/85A compare to standard Schottky rectifiers in ESD protection roles?
Unlike Schottky rectifiers-which exhibit higher reverse leakage (often >100 μA at 125 °C) and no inherent ESD hardening-the SE10PDHM3/85A uses an oxide planar silicon junction delivering IR ≤5 μA at 25 °C and <50 μA at 125 °C, plus certified >15 kV air-discharge immunity. Its 780 ns trr and 7.0 pF CJ enable cleaner clamping than Schottkys in fast-transient scenarios, while its 175 °C TJ max. exceeds typical Schottky limits. The SE10PDHM3/85A thus offers superior reliability in automotive ESD-critical rails where Schottkys may degrade or fail prematurely.
Is the SE10PDHM3/85A pin-compatible with other eSMP® rectifiers like SE10PBHM3/85A or SE10PGHM3/85A?
Yes, the SE10PDHM3/85A shares identical SMP (DO-220AA) package dimensions, lead finish, mounting pad layout, and pinout (anode/cathode orientation) with SE10PBHM3/85A, SE10PGHM3/85A, and SE10PJHM3/85A. All variants use the same mechanical outline and thermal footprint-enabling direct substitution on PCBs without layout changes. However, VRRM differs (100 V, 200 V, 400 V, 600 V), so electrical validation for reverse voltage margin remains essential when swapping the SE10PDHM3/85A into existing designs.
