Product details
Overview
SMBJ36AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for robust overvoltage protection of sensitive electronics. It features a 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR) at 1.0 mA test current, and clamps transients to ≤58.1 V at 10.3 A peak pulse current (IPPM) under 10/1000 µs waveform - deployed on power rails and signal lines in industrial motor drives and automotive ECUs.
For engineers reviewing the SMBJ36AHE3_A/H datasheet, SMBJ36AHE3_A/H pinout, SMBJ36AHE3_A/H application, or SMBJ36AHE3_A/H equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), clamping performance, and direct alternative part comparisons for ESD/surge protection design-in.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, leveraging glass-passivated junction technology for stable reverse-biased breakdown behavior. Its 600 W peak pulse power rating (10/1000 µs) and low incremental surge resistance enable effective suppression of inductive switching spikes and lightning-induced surges without latch-up or degradation.
The device is rated for -55 °C to +150 °C operating junction temperature, meets MSL Level 1 per J-STD-020 (260 °C reflow peak), and carries AEC-Q101 qualification - confirming suitability for automotive powertrain and body electronics where reliability under thermal cycling and mechanical stress is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 36 V - maximum continuous reverse voltage before significant leakage; sets operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 40.0–44.2 V at 1.0 mA - defines precise avalanche initiation point for predictable turn-on during overvoltage events |
| VC (Clamping Voltage) | ≤58.1 V at IPPM = 10.3 A - limits downstream voltage stress during 600 W transient, protecting 3.3 V/5 V/12 V ICs |
| IPPM (Peak Pulse Current) | 10.3 A (10/1000 µs) - quantifies surge-handling capacity; derates linearly above 25 °C ambient per Fig. 2 |
| PPPM (Peak Pulse Power) | 600 W - specifies single-pulse energy absorption capability; validated with 0.2" × 0.2" copper pad layout |
| RθJA (Junction-to-Ambient) | 100 °C/W - determines thermal rise under DC bias; requires PCB copper area management for sustained 5.0 W dissipation |
| TJmax | +150 °C - maximum junction temperature; enables operation in under-hood automotive environments |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002. Cathode indicated by band marking on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to system ground or lower-potential rail; completes clamping path during reverse transient |
| Cathode | Avalanche breakdown terminal | Connected to protected line (e.g., 36 V supply); initiates conduction when VAK ≥ VBR |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Enables single-event suppression of high-energy transients common in 24 V industrial control systems |
| AEC-Q101 qualified | Validated for automotive applications including engine control modules and ADAS power supplies |
| Glass passivated chip junction | Ensures long-term stability of VBR and leakage under humidity and thermal cycling stress |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow without popcorn cracking or delamination risk |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns response time) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36AHM3_A/H | Halogen-free, RoHS-compliant variant with identical electrical specs and AEC-Q101 qualification | No functional difference; selected where halogen-free material compliance is mandated | Choose SMBJ36AHM3_A/H when environmental compliance (IEC 61249-2-21) is required alongside automotive qualification |
| SMCJ36AHE3_A/H | Same VWM/VBR/VC, but SMC (DO-214AB) package with 1500 W PPPM and higher IPPM (17.3 A) | Used where higher surge margin is needed, e.g., outdoor telecom enclosures with extended lightning exposure | Choose SMCJ36AHE3_A/H only if board space allows larger SMC footprint and 2.5× higher pulse power is required |
Compared with SMBJ36AHE3_A/H, SMBJ36AHM3_A/H offers identical protection performance with halogen-free construction, while SMCJ36AHE3_A/H provides greater surge headroom in a larger package - selection depends strictly on environmental compliance needs and PCB layout constraints, not electrical interchangeability.

FAQ
What is the clamping voltage of SMBJ36AHE3_A/H at its rated peak pulse current?
The SMBJ36AHE3_A/H clamps to a maximum of 58.1 V at its specified peak pulse current of 10.3 A under the 10/1000 µs waveform. This value is measured with the device mounted on 0.2" × 0.2" copper pads per JEDEC standards and ensures downstream components see limited overvoltage stress during surge events. The SMBJ36AHE3_A/H maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C).
Is SMBJ36AHE3_A/H qualified for automotive applications?
Yes, SMBJ36AHE3_A/H is AEC-Q101 qualified, as confirmed in Vishay's ordering information and thermal characteristics notes. This qualification validates its robustness for automotive use cases including engine control units, body electronics, and infotainment power supplies. The SMBJ36AHE3_A/H undergoes stress testing for temperature cycling, humidity, and mechanical shock - meeting requirements for under-hood and cabin-mounted systems.
How does the SMBJ36AHE3_A/H differ from the SMBJ36AHM3_A/H variant?
The SMBJ36AHE3_A/H and SMBJ36AHM3_A/H share identical electrical specifications, package (SMB/DO-214AA), and AEC-Q101 qualification. The sole difference is material composition: SMBJ36AHM3_A/H uses halogen-free molding compound and terminations, satisfying IEC 61249-2-21 requirements. Both are RoHS-compliant, but SMBJ36AHM3_A/H is selected when halogen-free content is mandated by end-equipment environmental policies.
What is the maximum reverse leakage current of SMBJ36AHE3_A/H at its stand-off voltage?
At its 36 V stand-off voltage (VWM) and 25 °C ambient, the SMBJ36AHE3_A/H exhibits a maximum reverse leakage current (ID) of 1.0 µA. This low leakage ensures minimal power loss in always-on circuits and preserves battery life in automotive standby modes. Leakage remains within specification up to +125 °C, with gradual increase governed by junction temperature - no derating required below 85 °C.
Can SMBJ36AHE3_A/H be used in bidirectional protection circuits?
No, SMBJ36AHE3_A/H is a unidirectional TVS diode and is not suitable for bidirectional signal-line protection. For bidirectional applications such as RS-485 or USB data lines, Vishay specifies parts with "CA" suffix (e.g., SMBJ36CA). Using SMBJ36AHE3_A/H in reverse-biased AC paths would result in forward conduction and potential failure. Always verify polarity marking (cathode band) and match device type to circuit topology.
