Product details
Overview
SMAJ130A-M3/5A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on power and signal lines. It features a 130 V stand-off voltage (VWM), 144–159 V breakdown voltage (VBR) at 1 mA, 209 V maximum clamping voltage (VC) at 1.4 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the SMAJ130A-M3/5A datasheet, SMAJ130A-M3/5A pinout, SMAJ130A-M3/5A application, or SMAJ130A-M3/5A equivalent, key selection criteria include unidirectional polarity, 130 V working voltage, 209 V clamping under surge, thermal resistance (RθJA = 120 °C/W), and halogen-free RoHS-compliant M3 suffix packaging for high-reliability PCB assembly.
Technical Context
This TVS diode operates as a fast-acting shunt clamp during overvoltage events, leveraging an avalanche junction to divert transient energy away from protected circuitry. Its response time is sub-nanosecond, and it maintains stable clamping performance across -55 °C to +150 °C operating junction temperature range.
The device complies with IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and ISO 7637-2 (automotive load dump) immunity requirements when applied with proper PCB layout. Its 300 W derated pulse power above 78 V supports robust protection in 24 V and 48 V industrial bus systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC operating margin. |
| VBR (min/max) | 144 V / 159 V at 1 mA - Breakdown threshold range; ensures consistent turn-on across production lots. |
| VC @ IPPM | 209 V at 1.4 A - Clamped voltage during 10/1000 μs surge; determines maximum stress on downstream components. |
| PPPM | 400 W - Peak pulse power handling (10/1000 μs); enables protection against lightning-induced surges and inductive switching spikes. |
| IFSM | 40 A - Non-repetitive forward surge current (8.3 ms half-sine); supports temporary fault conditions without failure. |
| RθJA | 120 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; guides heatsinking and layout design. |
| TJ max | +150 °C - Maximum junction temperature; sets upper limit for ambient + power dissipation in sealed enclosures. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002. Cathode indicated by band; polarity-critical for unidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or return path; completes clamping loop during transient events. |
| Cathode | High-side connection point | Connected to protected line (e.g., 130 V rail); conducts avalanche current when VIN exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 μs) | Enables single-device protection against IEC 61000-4-5 Level 3 surges (1 kV/2 Ω) on 130 V lines. |
| 209 V clamping voltage at 1.4 A | Limits voltage overshoot to ≤ 1.6× VWM, preserving margin for 150 V-rated downstream MOSFETs or controllers. |
| Halogen-free, RoHS-compliant (M3 suffix) | Meets IPC-1752A material declaration requirements and automotive ELV directive for sustainable manufacturing. |
| MSL Level 1, 260 °C reflow compatible | Supports lead-free SMT assembly without preconditioning; eliminates moisture-related popcorning risk. |
| AEC-Q101 qualification option available | HE3/HM3 variants qualified for automotive powertrain and body electronics per stress test requirements. |
Applications
| Industrial Power Supply Protection | Automotive Sensor Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130A-E3/5A | Same electrical specs; RoHS-compliant but contains brominated flame retardants (non-halogen-free). | Acceptable for commercial-grade industrial equipment where halogen-free mandate does not apply. | Select when cost sensitivity outweighs halogen-free requirement and AEC-Q101 is not needed. |
| SMAJ130AHE3_A/I | Identical electrical parameters plus AEC-Q101 qualification; uses HE3 suffix and 13" tape/reel packaging. | Required for automotive powertrain, ADAS, or body control modules subject to OEM qualification. | Choose when automotive qualification, traceability, and extended temperature validation are mandatory. |
Compared with SMAJ130A-M3/5A, the E3 variant trades halogen-free compliance for lower unit cost in non-automotive settings, while the HE3 variant adds automotive qualification and different packaging - neither is pin-compatible drop-in replacement without verifying suffix-specific reliability documentation and reel logistics.

FAQ
What is the clamping voltage of SMAJ130A-M3/5A at its rated peak pulse current?
The SMAJ130A-M3/5A has a maximum clamping voltage (VC) of 209 V at 1.4 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured per IEC 61000-4-5 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMAJ130A-M3/5A maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C) with minimal drift.
Is SMAJ130A-M3/5A suitable for automotive applications?
SMAJ130A-M3/5A itself is not AEC-Q101 qualified; it is a commercial-grade halogen-free part. However, the functionally identical SMAJ130AHE3_A/I variant carries full AEC-Q101 qualification for automotive use. For automotive designs requiring qualification, engineers must specify the HE3 or HM3 suffix versions - the SMAJ130A-M3/5A is appropriate only for non-automotive industrial or telecom applications where AEC-Q101 is not mandated.
What is the meaning of the "M3" and "5A" suffixes in SMAJ130A-M3/5A?
In SMAJ130A-M3/5A, "M3" denotes halogen-free, RoHS-compliant construction meeting IPC-1752A material declarations, while "5A" specifies the packaging format: 7500-unit quantity on 13-inch diameter plastic tape and reel. This differs from "61" (1800 units on 7-inch reel) or "HE3" (AEC-Q101 qualified version). The SMAJ130A-M3/5A thus combines environmental compliance with high-volume SMT assembly readiness.
How does SMAJ130A-M3/5A compare to SMAJ120A-M3/5A in terms of voltage ratings?
SMAJ130A-M3/5A has a 130 V stand-off voltage (VWM) and 144–159 V breakdown range, whereas SMAJ120A-M3/5A is rated for 120 V VWM and 133–147 V VBR. The higher voltage grade allows SMAJ130A-M3/5A to be used on 130 V nominal rails without false triggering, offering tighter margin above system operating voltage than SMAJ120A-M3/5A. Both share identical package, power rating, and thermal characteristics.
Can SMAJ130A-M3/5A be used in bidirectional configurations?
No - SMAJ130A-M3/5A is strictly unidirectional, indicated by the "A" suffix (vs. "CA" for bidirectional). Its cathode band marks polarity, and it conducts only in reverse avalanche mode. For bidirectional protection at 130 V, the correct part is SMAJ130CA-M3/5A, which provides symmetrical clamping in both directions and omits the polarity marking. Using SMAJ130A-M3/5A in bidirectional circuits risks forward conduction and failure.
