Product details
Overview
SMBG5.0AHE3/52 from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in the SMBG (DO-215AA) package, rated for 5.0 V stand-off voltage, 6.4–7.07 V breakdown at 10 mA, 600 W peak pulse power (10/1000 μs), and AEC-Q101 qualification. It protects automotive sensor signal lines and MOSFET gate drivers against inductive switching transients.
For engineers reviewing the SMBG5.0AHE3/52 datasheet, SMBG5.0AHE3/52 pinout, SMBG5.0AHE3/52 application, or SMBG5.0AHE3/52 equivalent, this part delivers verified clamping performance (9.2 V max at 65.2 A), low leakage (<800 μA at 5.0 V), and automotive-grade reliability in a compact, RoHS-compliant, matte tin-plated SMBG package.
Technical Context
This unidirectional TVS diode operates as a voltage-clamping protection device across DC power rails or signal paths, activating when reverse voltage exceeds its 6.4–7.07 V breakdown range. Its glass-passivated junction ensures stable avalanche behavior and fast response time under transient stress.
Designed for automotive environments, SMBG5.0AHE3/52 meets AEC-Q101 stress testing requirements and supports operation from –55 °C to +150 °C junction temperature. Its 100 A IFSM rating enables robust handling of 8.3 ms half-sine surge events, while thermal resistance (RθJA = 100 °C/W) reflects standard PCB pad layout derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 6.4 V / 7.07 V at 10 mA - guaranteed avalanche onset window defining turn-on threshold tolerance |
| VC @ IPPM | 9.2 V at 65.2 A - clamped voltage during 600 W 10/1000 μs surge, limiting downstream stress |
| PPPM | 600 W - peak transient energy absorption capability per single pulse, duty cycle ≤ 0.01 % |
| ID @ VWM | <800 μA - low reverse leakage preserves signal integrity and minimizes standby power loss |
| IFSM | 100 A - surge current rating for 8.3 ms half-sine waveform, critical for inductive load switching protection |
| TJ max | +150 °C - maximum junction temperature enabling use in under-hood automotive locations |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0A-E3/52 | Same SMB (DO-214AA) package but lower 400 W PPPM rating; VBR 6.4–7.0 V, VC = 9.6 V @ 43.4 A | Limited to less severe surge environments (e.g., non-automotive consumer electronics) | Select SMBJ5.0A-E3/52 only if 400 W surge margin suffices and AEC-Q101 is not required. |
| SMAJ5.0AHE3/52 | Smaller SMA (DO-214AC) package; same 600 W rating but higher RθJA (150 °C/W); VBR 6.4–7.07 V, VC = 9.2 V | Thermal derating needed above 75 °C ambient; unsuitable for high-power-density automotive layouts | Choose SMAJ5.0AHE3/52 only when board space is constrained and thermal management allows. |
Compared with SMBJ5.0A-E3/52 and SMAJ5.0AHE3/52, SMBG5.0AHE3/52 provides superior thermal performance (RθJA = 100 °C/W), AEC-Q101 qualification, and DO-215AA mechanical robustness-making it the preferred choice for automotive and industrial applications demanding validated reliability and sustained surge handling.

FAQ
What is the clamping voltage of SMBG5.0AHE3/52 under maximum surge conditions?
The SMBG5.0AHE3/52 has a maximum clamping voltage (VC) of 9.2 V when subjected to its rated peak pulse current of 65.2 A (10/1000 μs waveform). This value is measured per ANSI/IEEE C62.35 and ensures protected circuitry remains below critical voltage thresholds during transient events. The SMBG5.0AHE3/52 maintains this clamping performance across its qualified temperature range.
Is SMBG5.0AHE3/52 suitable for bidirectional signal line protection?
No - SMBG5.0AHE3/52 is a unidirectional TVS diode, intended for DC-biased or ground-referenced protection paths. For bidirectional applications such as AC lines or differential buses, Vishay offers the SMBG5.0CA variant. Using SMBG5.0AHE3/52 on bidirectional signals risks forward conduction during negative half-cycles and invalidates its specified clamping behavior.
Does SMBG5.0AHE3/52 require derating at elevated ambient temperatures?
Yes - SMBG5.0AHE3/52 must be derated above TA = 25 °C per Figure 2 in Vishay document 88456. At 85 °C ambient, its peak pulse power drops to approximately 420 W (70 % of 600 W), and at 125 °C, it falls to ~240 W. Derating ensures junction temperature stays within the +150 °C limit and maintains reliability in automotive under-hood deployments.
What does the "HE3" suffix indicate in SMBG5.0AHE3/52?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification and matte tin-plated leads meeting J-STD-002 solderability standards. It distinguishes SMBG5.0AHE3/52 from industrial-grade "E3" variants (non-AEC-Q101) and halogen-free "HM3" versions. The HE3 marking confirms suitability for automotive electronics subject to stringent qualification and environmental compliance requirements.
Can SMBG5.0AHE3/52 be used in place of SMAJ5.0AHE3/52 without layout changes?
No - although both are 5.0 V unidirectional TVS diodes with AEC-Q101 and RoHS compliance, SMBG5.0AHE3/52 uses the larger SMBG (DO-215AA) package versus SMAJ5.0AHE3/52's SMA (DO-214AC) footprint. Pad layout, thermal relief, and mechanical clearance differ significantly; direct substitution requires PCB revision to accommodate the 6.48 mm × 5.97 mm SMBG outline and revised copper pad dimensions.
