Product details
Overview
SMBG36AHE3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) 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 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 on automotive sensor signal lines, industrial I/O ports, and DC power rails.
For engineers reviewing the SMBG36AHE3/52 datasheet, SMBG36AHE3/52 pinout, SMBG36AHE3/52 application, or SMBG36AHE3/52 equivalent, key selection criteria include clamping performance under 10.3 A surge, AEC-Q101 qualification for automotive use, RoHS-compliant matte tin-plated leads, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, leveraging a glass-passivated silicon junction for stable avalanche behavior. Its thermal resistance (RθJA = 100 °C/W) and junction temperature range (–55 °C to +150 °C) support operation in harsh environments, while MSL Level 1 moisture sensitivity enables standard reflow without baking.
The SMBG36AHE3/52 delivers fast response time (<1 ns) and low incremental surge resistance, enabling effective suppression of ESD, lightning-induced transients, and inductive switching spikes. Its 100 A IFSM (8.3 ms half-sine) rating supports high-energy surge events common in automotive load-dump scenarios.

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-E3/52 | Same VWM (36 V), but lower PPPM (600 W same), higher VC (60.0 V vs. 58.1 V), non-AEC-Q101 | Industrial-only use; lacks automotive qualification and tighter VC spec | Select when AEC-Q101 is not required and cost optimization is prioritized over clamping margin |
| SMCJ36AHE3/52 | Same VWM and AEC-Q101, but larger SMC (DO-214AB) package, higher IPPM (17.3 A), higher VC (58.1 V same), RθJA = 35 °C/W | Higher power handling and better thermal dissipation, but requires larger PCB area | Select when system-level surge currents exceed 10.3 A or board layout allows larger footprint for improved thermal margin |
Compared with SMBJ36A-E3/52 and SMCJ36AHE3/52, SMBG36AHE3/52 uniquely balances AEC-Q101 compliance, compact SMBG footprint, and lowest clamping voltage in its class - making it optimal for space-constrained automotive modules where voltage margin and qualification are non-negotiable.

FAQ
What is the clamping voltage of SMBG36AHE3/52 at its rated peak pulse current?
The SMBG36AHE3/52 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 is measured per JEDEC standards and reflects the actual voltage seen by protected circuitry during surge events - a critical parameter for ensuring downstream ICs remain within absolute maximum ratings. The SMBG36AHE3/52 achieves this with a low clamping ratio of approximately 1.45 relative to its VBR midpoint.
Is SMBG36AHE3/52 qualified for automotive applications?
Yes, SMBG36AHE3/52 is explicitly AEC-Q101 qualified, as confirmed in Vishay's official documentation (Document Number: 88456, Revision: 09-Jan-2024). This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD), validating its suitability for under-hood and body-control module deployments. The "HE3" suffix denotes RoHS compliance and AEC-Q101 qualification - a key differentiator from industrial-grade variants like SMBG36A-E3/52.
What is the package type and mounting specification for SMBG36AHE3/52?
SMBG36AHE3/52 uses the SMBG (DO-215AA) surface-mount package - a low-profile, gull-wing leaded outline measuring 4.57 mm × 3.94 mm × 2.10 mm. It is designed for reflow soldering on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. Its MSL Level 1 rating permits exposure to ambient conditions without baking prior to assembly.
How does SMBG36AHE3/52 differ from SMBJ36A-E3/52?
SMBG36AHE3/52 and SMBJ36A-E3/52 share identical VWM (36 V) and PPPM (600 W), but differ critically in qualification and clamping performance: SMBG36AHE3/52 is AEC-Q101 qualified and achieves a lower VC of 58.1 V vs. 60.0 V for SMBJ36A-E3/52. Additionally, SMBG36AHE3/52 uses the smaller SMBG (DO-215AA) package versus SMBJ's SMB (DO-214AA), offering higher board density. The "HE3" suffix confirms automotive-grade reliability not present in the "E3" industrial variant.
What is the maximum operating junction temperature for SMBG36AHE3/52?
The SMBG36AHE3/52 has a maximum operating junction temperature (TJ) of +150 °C, as specified in Vishay's datasheet (Document Number: 88456). This rating enables reliable operation in high-ambient environments such as engine control units, power distribution modules, and industrial motor drives. Its thermal resistance (RθJA = 100 °C/W) assumes mounting on 5.0 mm × 5.0 mm copper pads - derating is required above 25 °C ambient per Figure 2 in the datasheet.
