Product details
Overview
SMB10J36AHE3_B/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection with 1000 W peak pulse power (10/1000 µs), 36 V stand-off voltage (VWM), and 58.1 V clamping voltage (VC) at 17.2 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines in automotive powertrain and body electronics against inductive switching transients.
For engineers reviewing the SMB10J36AHE3_B/I datasheet, SMB10J36AHE3_B/I pinout, SMB10J36AHE3_B/I application, or SMB10J36AHE3_B/I equivalent, this AEC-Q101 qualified TVS offers verified clamping performance, low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for automotive-grade PCB reliability and automated SMT placement.
Technical Context
This unidirectional TVS operates by avalanche breakdown above its 40.0–44.2 V breakdown voltage (VBR at 1 mA), maintaining a stable 36 V reverse stand-off (VWM) with ≤1.0 µA leakage. Its fast response time (<1 ns) and low dynamic impedance enable effective suppression of ESD and load-dump transients before downstream components are stressed.
Thermally, it features a junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 72 °C/W when mounted on 5.0 mm × 5.0 mm copper pads. The glass-passivated chip junction ensures robustness under repetitive surge conditions up to 150 °C maximum junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin for 36 V nominal systems. |
| VBR min/max | 40.0 V / 44.2 V - Breakdown occurs within this range at 1 mA test current; ensures predictable turn-on threshold across production lot. |
| VC @ IPPM | 58.1 V at 17.2 A - Clamped voltage during 10/1000 µs surge; limits stress on protected ICs to <58.1 V under full-rated pulse. |
| PPPM | 1000 W - Peak pulse power handling capability; supports high-energy transients like ISO 7637-2 Pulse 5a (load dump). |
| IFSM | 100 A - Non-repetitive forward surge rating (8.3 ms half-sine); enables survival during short-circuit fault events in power rails. |
| Polarity | Unidirectional - Cathode-marked device; blocks reverse current until breakdown, ideal for DC-biased signal/power line protection. |
| AEC-Q101 | Qualified - Validated for automotive applications including engine control units, ADAS sensors, and infotainment power supplies. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; polarity indicated by cathode band.
| Pin/Terminal | Circuit Role | Design Meaning |

| Anode | Forward current entry / low-side reference | Connected to ground or lower-potential node; completes conduction path during transient clamp. |
| Cathode | Reverse-biased terminal / protected line connection | Connected to the line being protected (e.g., 36 V supply rail); avalanche conduction initiates here during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR and low leakage over temperature and lifetime; eliminates passivation-related drift in harsh environments. |
| MSL Level 1 rating | Allows unlimited floor life and reflow at peak 260 °C without baking - simplifies high-volume automotive SMT manufacturing. |
| Low incremental surge resistance | Minimizes VC rise under high di/dt surges, improving clamping precision for sensitive 3.3 V or 5 V logic interfaces downstream. |
| AEC-Q101 qualification | Validated for automotive temperature cycling, humidity testing, and mechanical shock - required for under-hood and chassis-mounted designs. |

IC Role / Device Role / Timing Role: Primary surge arrestor at DC input stage, upstream of DC-DC isolation and hot-swap controller. Use Value: 1000 W PPPM handles multi-kA induced surges; AEC-Q101 qualification ensures long-term reliability in uncontrolled environmental deployments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36AHE3_A/H | Same VWM (36 V), identical SMB package, but rated for 600 W PPPM (vs. 1000 W); lower IPPM (12.3 A vs. 17.2 A). | Not suitable for ISO 7637-2 Pulse 5a compliance; limited to lower-energy transients like ESD or IEC 61000-4-5 Level 3. | Select SMB10J36AHE3_B/I when full 1000 W surge immunity is required; choose SMBJ36AHE3_A/H only for cost-sensitive, non-automotive applications with lower surge exposure. |
| SMCJ36AHE3/73 | Higher-power SMC (DO-214AB) package; same VWM and VBR, but 1500 W PPPM and 24.9 A IPPM; larger footprint (7.11 mm × 6.22 mm vs. 4.57 mm × 3.94 mm). | Requires PCB layout change; better suited for industrial mains-connected equipment where space permits and higher energy absorption is needed. | Choose SMB10J36AHE3_B/I for space-constrained automotive modules; select SMCJ36AHE3/73 only when >1000 W margin or enhanced thermal dissipation is mandatory. |
Compared with SMBJ36AHE3_A/H and SMCJ36AHE3/73, SMB10J36AHE3_B/I uniquely balances 1000 W surge capability, AEC-Q101 qualification, and SMB footprint - making it the optimal choice for automotive 36 V subsystems where board area, reliability, and standardized surge compliance are jointly constrained.

FAQ
What is the clamping voltage of SMB10J36AHE3_B/I at its rated peak pulse current?
The SMB10J36AHE3_B/I has a maximum clamping voltage (VC) of 58.1 V at its rated peak pulse current (IPPM) of 17.2 A under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 standards and ensures protected circuits experience no more than 58.1 V during full-rated surge events. The SMB10J36AHE3_B/I datasheet specifies this parameter in the unidirectional electrical characteristics table on page 2.
Is SMB10J36AHE3_B/I qualified for automotive applications?
Yes, SMB10J36AHE3_B/I is AEC-Q101 qualified, as confirmed in the Vishay document 88422 revision 09-Jan-2024. The "HE3" suffix denotes RoHS-compliant and AEC-Q101 qualified construction, and the device meets stress tests including temperature cycling, humidity bias, and mechanical shock required for under-hood and chassis-mounted automotive electronics. This qualification applies directly to the SMB10J36AHE3_B/I variant.
What is the standoff voltage (VWM) and why is it important for SMB10J36AHE3_B/I?
The standoff voltage (VWM) of SMB10J36AHE3_B/I is 36 V - the maximum continuous reverse voltage the device can block without entering avalanche conduction. This matches common 36 V nominal automotive and industrial bus voltages, providing a safety margin below the 40.0–44.2 V breakdown range. Operating above VWM risks premature conduction and increased leakage; staying at or below 36 V ensures reliable blocking during normal operation while preserving surge headroom.
Does SMB10J36AHE3_B/I have a bidirectional version, and how does it differ?
No, SMB10J36AHE3_B/I is strictly unidirectional, as indicated by the "J" (not "JCA") in its naming and confirmed in the unidirectional electrical characteristics table. A bidirectional counterpart would be SMB8J36CAHE3_B/I (800 W PPPM, 13.8 A IPPM, same VWM/VBR), but it lacks the 1000 W rating and is not pin-compatible due to symmetrical terminal behavior. The SMB10J36AHE3_B/I must be oriented with cathode toward the protected line; reversing it causes forward conduction in normal operation.
What packaging and reel options are available for SMB10J36AHE3_B/I?
SMB10J36AHE3_B/I is supplied in 13-inch plastic tape and reel format with a base quantity of 3200 units per reel, as specified in the Vishay ordering information table (document 88422, page 3). The "I" in the suffix denotes this 13″ reel configuration, while "H" indicates the 7″ reel option (750 units). Both use E3-compliant matte tin plating and meet JESD 201 Class 2 whisker resistance requirements.
