Product details
Overview
SMBG36AHE3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMBG (DO-215AA) package, designed for clamping voltage transients on power and signal lines. It features 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR) at 1 mA, 58.1 V maximum clamping voltage (VC) at 10.3 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor protection and industrial I/O interface circuits.
For engineers reviewing the SMBG36AHE3/5B datasheet, SMBG36AHE3/5B pinout, SMBG36AHE3/5B application, or SMBG36AHE3/5B equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a fast-acting shunt clamp during overvoltage events, leveraging a glass-passivated silicon junction to achieve sub-nanosecond response time and stable clamping performance across -55 °C to +150 °C. Its unidirectional configuration enables integration into DC-biased rails where reverse conduction must be blocked.
The device meets J-STD-020 MSL Level 1 moisture sensitivity and supports reflow up to 260 °C peak. With 100 A non-repetitive forward surge rating (8.3 ms half-sine) and 1.0 µA max reverse leakage at VWM, it delivers robust protection for MOSFET gates and microcontroller I/O pins against ESD and inductive switching spikes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin. |
| VBR (min/max) | 40.0 V / 44.2 V at 1 mA - Ensures reliable triggering above system nominal voltage with process tolerance margin. |
| VC @ IPPM | 58.1 V at 10.3 A - Clamped voltage seen by protected circuit during 600 W transient; limits stress on downstream ICs. |
| PPPM | 600 W - Peak pulse power handling per 10/1000 µs waveform; validates immunity to IEC 61000-4-5 surge events. |
| IFSM | 100 A - Single half-sine surge rating (8.3 ms); supports protection of power supply inputs against load dump. |
| TJ max | +150 °C - Enables operation in under-hood automotive environments and high-temperature industrial enclosures. |
| AEC-Q101 | Qualified - Confirmed reliability for automotive electronics per stress test requirements including HTGB, HTRB, and TCT. |
Pinout & Package
Package: SMBG (DO-215AA), surface-mount, low-profile gull-wing lead frame with matte tin-plated terminals solderable per J-STD-002. Cathode indicated by band marking on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during clamping | Connected to protected line (e.g., 24 V rail); conducts surge current toward ground when VAK exceeds VBR. |
| Cathode | Current exit terminal during clamping | Connected to reference ground; establishes unidirectional conduction path and defines polarity-sensitive mounting orientation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, high-temperature reverse bias, and bond wire integrity. |
| 600 W peak pulse power | Withstands IEC 61000-4-5 Level 4 surges (4 kV line-to-earth) without degradation when mounted on 5.0 mm × 5.0 mm pads. |
| Glass passivated junction | Ensures stable VBR and low leakage (<1.0 µA) across humidity and thermal stress, critical for long-life industrial deployments. |
| MSL Level 1 rating | Enables single-reflow assembly without baking; compatible with standard SMT production lines using peak profile up to 260 °C. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes voltage overshoot during transients, reducing risk of latch-up or gate oxide damage in protected MOSFETs and MCUs. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A-E3/5B | Same VWM (36 V), but lower PPPM = 600 W (identical), higher VC = 59.0 V at 10.3 A; SMB (DO-214AA) package with larger footprint. | Less suitable for space-constrained automotive modules due to 0.255" × 0.155" vs. SMBG's 0.235" × 0.130" outline. | Select SMBG36AHE3/5B when board area is limited and AEC-Q101 qualification is mandatory. |
| SMCJ36AHE3/5B | Higher PPPM = 1500 W, same VWM/VBR, larger SMC (DO-214AB) package; identical AEC-Q101 qualification and thermal specs. | Better suited for primary-side AC/DC input protection where energy levels exceed 600 W capability. | Choose SMBG36AHE3/5B for secondary-side or signal-line protection where 600 W suffices and compactness is prioritized. |
Compared with SMBJ36A-E3/5B and SMCJ36AHE3/5B, SMBG36AHE3/5B offers optimal balance of AEC-Q101 compliance, 600 W surge capacity, and minimal PCB footprint - making it preferred for space-limited automotive and industrial control nodes requiring validated reliability without over-engineering.

FAQ
What is the clamping voltage of SMBG36AHE3/5B at its rated peak pulse current?
The SMBG36AHE3/5B has a maximum clamping voltage (VC) of 58.1 V at 10.3 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value ensures protected circuits remain within safe operating limits during standardized surge events. The SMBG36AHE3/5B achieves this with low incremental surge resistance, directly contributing to consistent transient suppression performance across its operational lifetime.
Is SMBG36AHE3/5B qualified for automotive applications?
Yes, SMBG36AHE3/5B is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias, temperature cycling, and unbiased highly accelerated stress testing. This certification confirms its suitability for under-hood and chassis-mounted automotive electronics. The SMBG36AHE3/5B also carries HE3 suffix denoting AEC-Q101 qualification and RoHS compliance per Vishay's ordering nomenclature.
What package type does SMBG36AHE3/5B use, and what are its mounting requirements?
SMBG36AHE3/5B uses the SMBG (DO-215AA) surface-mount package with gull-wing leads and a cathode band marking. It requires mounting on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal for rated 600 W pulse power dissipation. The SMBG36AHE3/5B is rated MSL Level 1 and supports reflow profiles up to 260 °C peak temperature without preconditioning.
How does SMBG36AHE3/5B differ from bidirectional TVS diodes like SMBG36CA?
SMBG36AHE3/5B is unidirectional and blocks reverse current beyond VWM, whereas SMBG36CA is bidirectional and clamps in both polarities. The SMBG36AHE3/5B exhibits 1.0 µA max reverse leakage at 36 V, while SMBG36CA would conduct in reverse above its VBR. Use SMBG36AHE3/5B on DC-biased lines such as power rails; choose SMBG36CA only for AC-coupled or floating signal paths where symmetric clamping is required.
What is the maximum operating junction temperature for SMBG36AHE3/5B?
The SMBG36AHE3/5B has a maximum operating junction temperature (TJ) of +150 °C, enabling deployment in high-ambient environments such as engine control units and industrial motor drives. Its thermal resistance from junction to ambient (RθJA) is 100 °C/W when mounted on recommended pad layout, allowing accurate thermal design for sustained surge duty cycles. This specification is explicitly confirmed in the Vishay SMBG5.0A–SMBG188CA datasheet revision 09-Jan-2024.
