Product details
Overview
SMBG10AHE3/52 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 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 17.0 V maximum clamping voltage (VC) at 35.3 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed in automotive power line and sensor interface protection.
For engineers reviewing the SMBG10AHE3/52 datasheet, SMBG10AHE3/52 pinout, SMBG10AHE3/52 application, or SMBG10AHE3/52 equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (−55 to +150 °C), and bidirectional/unidirectional polarity context critical for ESD/surge co-design and layout validation.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal bias it presents high impedance (<1 μA leakage at 10 V), then rapidly avalanches when reverse voltage exceeds VBR to clamp transients within VC. Its glass-passivated junction ensures stable breakdown and low incremental surge resistance, enabling repeatable 600 W surge handling at 0.01% duty cycle.
Designed for surface-mount automated placement, SMBG10AHE3/52 uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), and is qualified to AEC-Q101 for automotive under-hood and chassis applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before clamping begins; defines safe signal line operating margin. |
| VBR (min/max) | 11.1 V / 12.3 V at IT = 1 mA - Tight breakdown window ensures predictable turn-on threshold across production lots. |
| VC @ IPPM | 17.0 V at 35.3 A - Clamping voltage during 10/1000 μs surge; determines protected IC's maximum transient stress level. |
| PPPM | 600 W - Peak transient energy absorption capability; supports IEC 61000-4-5 Level 4 (4 kV) surge compliance with proper PCB layout. |
| TJ max | +150 °C - Enables operation in under-hood automotive environments without derating below full power. |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient on standard 0.2" × 0.2" copper pads; guides heatsinking requirements. |
| AEC-Q101 | Qualified - Validated for automotive reliability including HTOL, TC, UHAST, and ESD testing per AEC specification. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A-E3/52 | Same VWM (10 V), but lower PPPM (600 W vs. SMBJ series' 600 W), identical SMB package; slightly higher VC (18.0 V vs. 17.0 V). | Less stringent clamping margin; suitable where 1.0 V higher VC is acceptable for cost-sensitive industrial designs. | Select SMBJ10A-E3/52 only if AEC-Q101 qualification is not required - SMBG10AHE3/52 is AEC-Q101 qualified; SMBJ10A-E3/52 is not. |
| 1.5SMC10A | Same VWM and VBR range, but larger SMC (DO-214AB) package; RθJA ≈ 30 °C/W vs. 100 °C/W; higher IPPM (43.3 A) due to thermal advantage. | Better thermal performance allows sustained surge repetition; requires larger PCB area and different pad layout. | Choose 1.5SMC10A when board space permits and higher thermal mass is needed for repetitive surge environments (e.g., motor drive controls). |
Compared with SMBJ10A-E3/52 and 1.5SMC10A, SMBG10AHE3/52 uniquely combines AEC-Q101 qualification, SMBG footprint efficiency, and tight 17.0 V clamping - making it optimal for space-constrained automotive modules requiring validated reliability and precise voltage limiting.

FAQ
What is the clamping voltage of SMBG10AHE3/52 at its rated peak pulse current?
The SMBG10AHE3/52 has a maximum clamping voltage (VC) of 17.0 V at 35.3 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured under standardized test conditions per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBG10AHE3/52 maintains this clamping performance across its qualified operating temperature range.
Is SMBG10AHE3/52 qualified for automotive applications?
Yes, SMBG10AHE3/52 is explicitly AEC-Q101 qualified, as confirmed in the Vishay datasheet (Document Number: 88456, Revision: 09-Jan-2024). This qualification covers stress tests including high-temperature operating life, temperature cycling, unbiased highly accelerated stress testing, and ESD. The "HE3" suffix denotes RoHS-compliant, AEC-Q101-qualified industrial grade, making SMBG10AHE3/52 suitable for automotive powertrain, body electronics, and ADAS modules.
What does the "HE3/52" suffix mean in SMBG10AHE3/52?
The "HE3" suffix indicates RoHS-compliant, AEC-Q101-qualified construction with matte tin-plated leads meeting J-STD-002 solderability standards. The "/52" denotes packaging in 7" diameter plastic tape and reel, with 750 units per reel. This ordering code aligns with Vishay's standardized nomenclature for SMBG-series TVS diodes and ensures traceability to qualified manufacturing lots and material specifications for SMBG10AHE3/52.
Can SMBG10AHE3/52 be used in bidirectional configurations?
No, SMBG10AHE3/52 is a unidirectional TVS diode, as indicated by the "A" (not "CA") suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., SMBG10CA). Using SMBG10AHE3/52 in bidirectional signal paths would result in forward conduction during negative transients, potentially damaging the device or failing to protect. For bidirectional protection, select SMBG10CA or equivalent - SMBG10AHE3/52 is strictly for unidirectional clamping to ground.
What is the maximum junction temperature rating for SMBG10AHE3/52?
The SMBG10AHE3/52 has a maximum junction temperature (TJ max) of +150 °C, specified in the Absolute Maximum Ratings table. This rating applies under steady-state and pulsed conditions and enables reliable operation in under-hood automotive environments and industrial enclosures without forced cooling. Derating curves in Figure 2 of the datasheet define allowable power reduction above 25 °C ambient, ensuring SMBG10AHE3/52 remains within safe thermal limits across its full operating range.
