Product details
Overview
SMCJ130AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 130 V standoff voltage (VWM), 144–159 V breakdown voltage (VBR), 209 V maximum clamping voltage (VC) at 7.2 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 µs waveform.
For engineers reviewing the SMCJ130AHM3_A/H datasheet, SMCJ130AHM3_A/H pinout, SMCJ130AHM3_A/H application, or SMCJ130AHM3_A/H equivalent, key selection criteria include clamping performance under 10/1000 µs surge, thermal resistance (RθJA = 75 °C/W), AEC-Q101 qualification status, halogen-free RoHS compliance, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCJ130AHM3_A/H operates as a unidirectional avalanche diode with glass-passivated junction, enabling fast response time (<1 ns) and low incremental surge resistance. Its clamping behavior is defined per ANSI/IEEE C62.35, with VC measured at IPPM under standardized 10/1000 µs waveform conditions.
Thermally, it supports operation from –55 °C to +150 °C junction temperature, with derating applied above TA = 25 °C per Figure 2. The device is qualified to AEC-Q101 and meets JESD201 Class 2 whisker resistance, with matte tin-plated leads solderable per J-STD-002 and JESD22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before clamping begins; defines safe signal line operating margin. |
| VBR min/max | 144 V / 159 V at IT = 1 mA - Confirmed breakdown range ensures reliable turn-on during overvoltage events. |
| VC @ IPPM | 209 V at 7.2 A - Clamping voltage under full 1500 W surge; determines protected circuit's maximum transient exposure. |
| PPPM | 1500 W - Peak pulse power handling with 10/1000 µs waveform; defines single-event surge robustness. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance on standard PCB pad layout; critical for thermal design margin. |
| TJ max | +150 °C - Maximum junction temperature; sets upper limit for ambient + self-heating in high-reliability applications. |
| Package | SMC (DO-214AB) - Surface-mount outline with 8.13 mm × 6.22 mm footprint; compatible with standard SMT reflow profiles. |
Pinout & Package

IC Role / Device Role / Timing Role: Primary surge clamp on midspan PSE output, coordinated with secondary TVS on PD side. Use Value: Withstands repeated 10/1000 µs surges up to 1500 W while maintaining 130 V operational headroom-critical for IEEE 802.3bt compatibility. |
Use Scenario: Suppressing commutation spikes from brushed DC motors in smart home appliances (e.g., vacuum cleaners, blenders). IC Role / Device Role / Timing Role: Mounted across motor terminals to absorb inductive kickback energy. Use Value: Handles 200 A non-repetitive forward surge (IFSM) and clamps spikes to 209 V, preventing MOSFET drain-source breakdown in half-bridge drivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130AHM3_A/H | Lower PPPM (600 W), smaller SMB (DO-214AA) package, same VWM/VBR/VC specs. | Suitable for space-constrained designs with lower surge threat levels (e.g., consumer USB ports). | Select when board area is limited and surge energy does not exceed 600 W; verify thermal margin due to higher RθJA. |
| SMCJ130AHE3_A/H | Same electrical specs and package, but RoHS-compliant commercial grade (non-halogen-free, no AEC-Q101). | Applicable in industrial/commercial systems where automotive qualification is not required. | Choose for cost-sensitive non-automotive applications; retains identical clamping and layout compatibility. |
Compared with SMCJ130AHM3_A/H, SMBJ130AHM3_A/H trades surge capacity for footprint reduction, while SMCJ130AHE3_A/H offers identical protection performance without halogen-free or AEC-Q101 assurance-enabling tiered sourcing based on environmental and reliability requirements.

FAQ
What is the clamping voltage of SMCJ130AHM3_A/H under maximum rated surge current?
The SMCJ130AHM3_A/H has a maximum clamping voltage (VC) of 209 V when subjected to its rated peak pulse current (IPPM) of 7.2 A using a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. The SMCJ130AHM3_A/H maintains this clamping performance across its qualified operating temperature range.
Is SMCJ130AHM3_A/H qualified for automotive applications?
Yes, SMCJ130AHM3_A/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HM3" and documentation in datasheet 88394. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and mechanical shock-validating suitability for under-hood and chassis-mounted automotive electronics. The SMCJ130AHM3_A/H meets these requirements without derating in standard mounting configurations.
What is the thermal resistance of SMCJ130AHM3_A/H, and how does it affect PCB layout?
The SMCJ130AHM3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. This value assumes minimum recommended pad layout per Vishay's package drawing. To maintain safe junction temperatures, designers must ensure adequate copper area and avoid excessive trace length between the SMCJ130AHM3_A/H anode/cathode and their respective ground/power planes.
How does the HM3 suffix differ from HE3 in SMCJ130A variants?
The HM3 suffix in SMCJ130AHM3_A/H indicates halogen-free, RoHS-compliant, and AEC-Q101 qualified construction, whereas HE3 denotes RoHS-compliant and AEC-Q101 qualified but not halogen-free. Both share identical electrical specifications and SMC package dimensions, but HM3 meets stricter material content requirements (e.g., IEC 61249-2-21). The SMCJ130AHM3_A/H is selected when halogen-free compliance is mandated by end-equipment environmental policies.
Can SMCJ130AHM3_A/H be used in bidirectional protection circuits?
No, SMCJ130AHM3_A/H is a unidirectional TVS diode, identifiable by its cathode band marking and specified VBR/VC parameters for reverse-biased operation only. For bidirectional protection, Vishay offers the SMCJ130CA variant (with CA suffix), which provides symmetrical clamping in both polarities. Using SMCJ130AHM3_A/H in bidirectional applications would result in forward conduction and potential failure during negative transients.
