Product details
Overview
SMCJ130HE3/9AT from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 130 V standoff voltage (VWM), 144–159 V breakdown range (VBR at 1 mA), 209 V clamping voltage (VC) at 7.2 A peak pulse current, 1500 W peak pulse power rating (10/1000 µs), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMCJ130HE3/9AT datasheet, SMCJ130HE3/9AT pinout, SMCJ130HE3/9AT application, or SMCJ130HE3/9AT equivalent, this device is selected for high-energy surge suppression in automotive power distribution modules, industrial motor drive control inputs, and telecom DC feed protection where stable clamping, low leakage (<1 µA at VWM), and MSL Level 1 reflow compatibility are critical.
Technical Context
The SMCJ130HE3/9AT operates as a silicon avalanche diode with unidirectional polarity-cathode marked by a band-and delivers precise voltage limiting via controlled reverse-biased avalanche breakdown. Its thermal resistance (RθJA = 75 °C/W, RθJL = 15 °C/W) supports reliable operation up to 150 °C junction temperature under transient stress.
It complies with ANSI/IEEE C62.35 for surge testing, withstands 200 A non-repetitive forward surge (8.3 ms half-sine), and meets J-STD-020 MSL Level 1 with 260 °C peak reflow profile. The matte tin-plated leads ensure solderability per J-STD-002 and JESD 22-B102, while the HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin. |
| VBR (min/max) | 144 V / 159 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on across production lot. |
| VC @ IPPM | 209 V at 7.2 A - Clamped voltage during 10/1000 µs surge; determines maximum stress on downstream ICs. |
| PPPM | 1500 W - Peak pulse power handling capability; enables protection against IEC 61000-4-5 Level 4 surges. |

Use Value: Tight VBR tolerance (144–159 V) ensures consistent trip threshold across temperature and lifetime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130AHE3/9AT | Lower PPPM (600 W), smaller SMB package (DO-214AA), same VWM/VC specs. | Suitable for space-constrained PCBs with lower surge threat profiles (e.g., consumer IoT gateways). | Select when board area is limited and IEC 61000-4-5 Level 3 compliance suffices. |
| SMCJ130A-E3/9AT | Same electrical specs but commercial-grade (non-AEC-Q101); E3 suffix only (no HE3). | Appropriate for industrial automation panels not requiring automotive qualification. | Choose for cost-sensitive designs where AEC-Q101 is not mandated and traceability is less critical. |
Compared with SMCJ130HE3/9AT, the SMBJ130AHE3/9AT trades surge capacity for footprint reduction, while the SMCJ130A-E3/9AT removes automotive qualification-both retain identical clamping behavior but differ in reliability assurance and mechanical robustness.

FAQ
What is the clamping voltage of the SMCJ130HE3/9AT under a 10/1000 µs surge?
The SMCJ130HE3/9AT has a maximum clamping voltage (VC) of 209 V at 7.2 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMCJ130HE3/9AT maintains this clamping performance across its specified operating temperature range.
Is the SMCJ130HE3/9AT suitable for automotive applications?
Yes-the SMCJ130HE3/9AT carries the HE3 suffix, confirming full AEC-Q101 qualification per Vishay's documentation. It is rated for operation from –55 °C to +150 °C, passes JESD 201 Class 2 whisker testing, and meets MSL Level 1 reflow requirements. These attributes make the SMCJ130HE3/9AT appropriate for under-hood ECUs, body control modules, and ADAS power supplies.
How does the SMCJ130HE3/9AT differ from the SMCJ130A-E3/9AT?
The SMCJ130HE3/9AT adds AEC-Q101 qualification and JESD 201 Class 2 whisker resistance versus the commercial-grade SMCJ130A-E3/9AT. Both share identical electrical parameters (VWM, VBR, VC, PPPM), DO-214AB packaging, and RoHS compliance. The SMCJ130HE3/9AT is designated for automotive and high-reliability industrial use, whereas the SMCJ130A-E3/9AT targets general-purpose applications.
What is the reverse leakage current of the SMCJ130HE3/9AT at its standoff voltage?
At its 130 V standoff voltage (VWM), the SMCJ130HE3/9AT exhibits a maximum reverse leakage current (ID) of 1 µA at 25 °C. This ultra-low leakage ensures minimal power loss in always-on systems and prevents false triggering in high-impedance monitoring circuits. Leakage remains below 5 µA up to +125 °C per Vishay's derating curves.
Can the SMCJ130HE3/9AT be used in bidirectional configurations?
No-the SMCJ130HE3/9AT is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. For bidirectional operation, Vishay specifies the "CA" variant (e.g., SMCJ130CA). Using the SMCJ130HE3/9AT in reverse-biased AC or symmetrical surge scenarios would result in forward conduction and potential failure. Always match suffix ("A" vs. "CA") to circuit polarity requirements.
