Product details
Overview
SMB10J36AHE3_A/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on power and signal lines. It features a 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR) at 1 mA, 1000 W peak pulse power (10/1000 µs), 17.2 A peak pulse current (IPPM), and clamps to ≤58.1 V under surge. It is AEC-Q101 qualified and used to protect automotive sensor interfaces and power rails against inductive switching transients.
For engineers reviewing the SMB10J36AHE3_A/H datasheet, SMB10J36AHE3_A/H pinout, SMB10J36AHE3_A/H application, or SMB10J36AHE3_A/H equivalent, key selection criteria include clamping voltage vs. protected IC's absolute maximum rating, VWM margin relative to operating voltage, AEC-Q101 compliance for automotive use, and thermal derating above 25 °C ambient.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for fast response (<1 ns) and low incremental surge resistance, enabling effective suppression of ESD, lightning-induced surges, and load-dump transients. Its unidirectional polarity provides forward conduction capability with VF ≈ 3.5 V at 50 A, supporting bidirectional protection when paired with a series diode or used in DC-biased lines.
The device operates across -55 °C to +150 °C junction temperature, with thermal resistance RθJA = 72 °C/W (on 0.2" × 0.2" copper pads) and RθJL = 20 °C/W, making it suitable for compact automotive PCB layouts where heat dissipation is constrained. It meets J-STD-020 MSL Level 1 and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 36 V - Maximum continuous reverse voltage before significant leakage; must exceed system operating voltage by ≥10 % to avoid false triggering. |
| VBR (Breakdown Voltage) | 40.0–44.2 V at 1 mA - Confirmed breakdown threshold; ensures reliable turn-on during overvoltage events above nominal rail. |
| VC (Clamping Voltage) | ≤58.1 V at IPPM - Peak voltage seen by protected circuit during 10/1000 µs surge; must stay below downstream IC's absolute max rating. |
| PPPM (Peak Pulse Power) | 1000 W (10/1000 µs) - Energy-handling capacity for standardized surge waveforms; defines single-event robustness. |
| IPPM (Peak Pulse Current) | 17.2 A (10/1000 µs) - Corresponding surge current at VC; used to size upstream fusing and trace routing. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood automotive environments. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002. Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |

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 (10.3 A). | Not suitable for high-energy load-dump events; limited to ESD and low-energy transients. | Select only if system-level surge testing confirms ≤600 W requirement and space constraints prohibit larger packages. |
| SMCJ36AHE3_A/H | Same electrical specs (VWM, VBR, VC), but in larger SMC (DO-214AB) package with 1500 W PPPM and 24.5 A IPPM. | Higher thermal mass supports repeated surges in high-duty-cycle industrial environments. | Choose when board layout allows larger footprint and application demands >1000 W single-pulse or multi-pulse endurance. |

FAQ
What is the clamping voltage of SMB10J36AHE3_A/H at its rated peak pulse current?
The SMB10J36AHE3_A/H has a maximum clamping voltage (VC) of 58.1 V when subjected to its rated 17.2 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured at TJ = 25 °C and defines the upper voltage limit imposed on protected circuitry during surge events. Designers must verify that this clamping level remains safely below the absolute maximum ratings of downstream components. The SMB10J36AHE3_A/H maintains this performance across its full operating temperature range with appropriate derating.
Is SMB10J36AHE3_A/H suitable for bidirectional signal line protection?
No-SMB10J36AHE3_A/H is a unidirectional TVS diode, intended for DC-biased lines such as power rails or single-ended signals referenced to ground. For true bidirectional protection (e.g., USB, RS-485, or AC-coupled data lines), a bidirectional variant like SMB10J36CAHE3_A/H must be used. Using SMB10J36AHE3_A/H on an AC signal risks forward conduction during negative half-cycles, potentially disrupting signal integrity or damaging the diode. Always match polarity type to system bias architecture.
How does the AEC-Q101 qualification of SMB10J36AHE3_A/H impact its use in automotive designs?
The AEC-Q101 qualification of SMB10J36AHE3_A/H certifies that the device has passed accelerated stress tests-including temperature cycling, high-temperature reverse bias, and ESD-required for automotive electronic components. This validates its reliability in under-hood and cabin environments where thermal shock, vibration, and long service life (>15 years) are critical. Designers can deploy SMB10J36AHE3_A/H in safety-critical modules (e.g., airbag controllers, ADAS sensors) without additional qualification effort, provided layout and derating follow Vishay's application guidelines.
What is the thermal resistance of SMB10J36AHE3_A/H, and how does it affect PCB layout?
SMB10J36AHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, and junction-to-lead resistance (RθJL) of 20 °C/W. These values dictate minimum pad size and copper pour requirements: reducing pad area increases RθJA, risking thermal runaway during repetitive surges. For automotive applications with sustained ambient temperatures >85 °C, designers must apply derating curves from Figure 2 of the datasheet and may add thermal vias to inner layers to improve heat dissipation.
Can SMB10J36AHE3_A/H replace SMBJ36AHE3_A/H in an existing design without layout changes?
Yes-SMB10J36AHE3_A/H shares identical SMB (DO-214AA) package dimensions, pinout, and solder footprint with SMBJ36AHE3_A/H, enabling drop-in replacement. However, its higher 1000 W PPPM rating requires verification that the PCB copper traces and upstream fusing can handle the increased peak current (17.2 A vs. 10.3 A). No layout change is needed, but system-level surge testing should confirm no unintended interaction with adjacent components or ground bounce under higher-energy transients.
