Product details
Overview
P4SMA130AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in SMA (DO-214AC) package, designed for clamping voltage transients on power and signal lines. It features 130 V standoff voltage (VWM), 179 V maximum clamping voltage (VC) at 1.7 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the P4SMA130AHM3_A/I datasheet, P4SMA130AHM3_A/I pinout, P4SMA130AHM3_A/I application, or P4SMA130AHM3_A/I equivalent, key selection criteria include clamping performance under 10/1000 µs surge, AEC-Q101 qualification status, thermal resistance (RθJA = 120 °C/W), unidirectional polarity marking, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a unidirectional clamp, leveraging a glass-passivated silicon junction to achieve fast response time (<1 ns) and low incremental surge resistance. Its breakdown voltage (VBR) is specified at 124–137 V (min/max) with 1 mA test current, ensuring precise overvoltage threshold activation before downstream component damage.
The device is rated for 150 °C maximum junction temperature and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. Its AEC-Q101 qualification (via HM3 suffix) confirms suitability for automotive electronics where reliability under thermal cycling and mechanical stress is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 111 V - Maximum continuous reverse working voltage before clamping initiates; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 124–137 V at 1 mA - Confirmed voltage range at which avalanche conduction begins; ensures predictable turn-on behavior. |
| VC (Clamping Voltage) | 179 V at IPPM = 1.7 A - Peak voltage seen by protected circuit during 10/1000 µs transient; directly limits stress on downstream ICs. |
| PPPM (Peak Pulse Power) | 400 W - Sustained energy absorption capability under standard 10/1000 µs surge; derates above 25 °C per Fig. 2. |
| ID (Reverse Leakage) | 1.0 µA at VWM - Minimal leakage current at rated standoff voltage; preserves low-power system integrity. |
| RθJA | 120 °C/W - Junction-to-ambient thermal resistance; determines required PCB copper area (0.2" × 0.2") for thermal management. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock testing. |
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 on unidirectional variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction | Connected to ground or low-side reference in unidirectional protection configurations. |
| Cathode | Current exit terminal during forward conduction; marked with band | Connected to protected line (e.g., 12 V rail or signal input); conducts avalanche current during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 µs) | Enables robust protection against IEC 61000-4-5 Level 3 surges without derating in standard layouts. |
| Glass passivated chip junction | Ensures stable VBR over lifetime and immunity to moisture-induced parameter drift in humid environments. |
| MSL Level 1, 260 °C peak reflow | Supports single-pass lead-free reflow assembly without popcorn or delamination risk. |
| AEC-Q101 qualified (HM3 suffix) | Validates suitability for automotive powertrain, body control, and ADAS subsystems requiring zero-failure field performance. |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (e.g., load dump, ESD), improving protection margin. |
Applications
| Automotive Power Supply Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V power rails in vehicle ECUs against load dump and ISO 7637-2 pulses.

Use Value: 111 V VWM allows operation with 90–132 VAC input while maintaining ≥15 % margin to VBR. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130A-E3/5A | Same VWM (111 V), VC = 179 V, but rated for 400 W with 8.3 ms half-sine surge; no AEC-Q101 qualification. | Commercial/industrial use only; not validated for automotive temperature cycling or humidity bias stress. | Select when AEC-Q101 is not required and cost sensitivity outweighs automotive qualification needs. |
| 1.5SMC130A | Higher package thermal resistance (RθJA ≈ 150 °C/W), same VWM/VC specs; DO-214AB (SMB) package, larger footprint. | Requires more PCB area; less suitable for dense automotive modules where SMA's compact size is critical. | Choose only if existing layout uses SMB footprint and thermal derating can be accommodated via larger copper pours. |
Compared with SMAJ130A-E3/5A and 1.5SMC130A, P4SMA130AHM3_A/I delivers identical clamping performance in a smaller SMA package while providing AEC-Q101 validation - making it the preferred choice for space-constrained automotive designs requiring certified reliability.

FAQ
What is the clamping voltage of P4SMA130AHM3_A/I at its rated peak pulse current?
The P4SMA130AHM3_A/I has a maximum clamping voltage (VC) of 179 V at 1.7 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per Figure 1 in the Vishay datasheet (Doc. #88367) and defines the upper voltage limit imposed on protected circuits during surge events. The low VC ensures downstream ICs with 200 V absolute maximum ratings remain within safe operating margins.
Is P4SMA130AHM3_A/I qualified for automotive applications?
Yes, P4SMA130AHM3_A/I is AEC-Q101 qualified, as confirmed by the "HM3" suffix and documentation in Vishay's P4SMA series datasheet (Rev. 09-Jan-2024). This qualification covers temperature cycling, high-temperature operating life, and mechanical shock testing - validating its use in automotive body electronics, infotainment systems, and ADAS power domains where field reliability is mandatory.
What does the "_A/I" suffix mean in P4SMA130AHM3_A/I?
In P4SMA130AHM3_A/I, "A" denotes the revision level of the AEC-Q101 qualification, and "I" specifies the packaging format: 13-inch diameter plastic tape and reel, with 7500 units per reel. This matches Vishay's ordering information table (page 3 of Doc. #88367), where "/I" explicitly indicates the high-volume reel configuration for automated SMT placement.
How does the thermal resistance of P4SMA130AHM3_A/I affect PCB layout?
P4SMA130AHM3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W, measured on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain TJ ≤ 150 °C under 400 W pulse conditions, designers must adhere to this pad layout - reducing copper area increases RθJA and risks thermal runaway during repetitive surges. No heatsink is required for single-event protection.
Can P4SMA130AHM3_A/I replace bidirectional TVS diodes in circuit designs?
No, P4SMA130AHM3_A/I is strictly unidirectional, with cathode marked by a band and intended for DC-biased lines like power rails or grounded signal paths. Bidirectional variants (e.g., P4SMA130CA) are required for AC-coupled or floating lines such as data buses or transformer secondaries. Substituting P4SMA130AHM3_A/I in bidirectional roles will result in forward conduction and potential failure during negative transients.
