Product details
Overview
P4SMA130AHM3/I 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 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 industrial and automotive electronics.
For engineers reviewing the P4SMA130AHM3/I datasheet, P4SMA130AHM3/I pinout, P4SMA130AHM3/I application, or P4SMA130AHM3/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 120 °C/W), and halogen-free RoHS-compliant construction per JESD201 Class 2 whisker test - all critical for ESD/surge protection design validation and long-term supply assurance.
Technical Context
The P4SMA130AHM3/I operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology for stable breakdown behavior and fast response (<1 ns). Its clamping action begins at 124 V (VBR min) and fully engages by 179 V (VC), limiting transient energy delivered to downstream circuitry during inductive switching or lightning-induced surges.
Rated for 150 °C maximum junction temperature and compliant with AEC-Q101, it supports automotive-grade reliability under repetitive surge conditions (0.01% duty cycle). The SMA package enables automated placement and meets UL 94 V-0 flammability, with matte tin-plated leads solderable per J-STD-002 and JESD22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 111 V - Maximum continuous reverse operating voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 124–137 V at 1 mA - Avalanche onset range; ensures predictable turn-on during overvoltage events without premature leakage. |
| VC (Clamping Voltage) | 179 V at 1.7 A (10/1000 µs) - Peak voltage seen by protected circuit during worst-case surge; directly limits stress on downstream components. |
| PPPM (Peak Pulse Power) | 400 W - Energy-handling capacity for standardized 10/1000 µs transients; sufficient for IEC 61000-4-5 Level 3 surge immunity. |
| ID (Reverse Leakage) | 1.0 µA at VWM - Ultra-low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
| RθJA | 120 °C/W - Thermal resistance from junction to ambient; informs PCB copper pad sizing (0.2" × 0.2") for reliable power dissipation. |
| AEC-Q101 Qualified | Yes - Validated for automotive applications including engine control, body electronics, and ADAS sensor interfaces. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile case with cathode band marking. Molding compound meets UL 94 V-0; terminals are matte tin-plated for robust solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias | Connected to ground or lower-potential rail in unidirectional TVS configuration; enables clamping of positive transients on the cathode side. |
| Cathode | Current exit terminal in forward bias; marked with band | Connected to protected line (e.g., 12 V rail or signal trace); conducts surge current to ground when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 µs) | Enables robust protection against IEC 61000-4-5 surges without derating below 91 V - critical for 12 V/24 V automotive systems. |
| Glass passivated chip junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure per AEC-Q101 requirements. |
| Halogen-free, RoHS-compliant (HM3 suffix) | Meets automotive environmental standards and JESD201 Class 2 whisker resistance - eliminates tin whisker risk in high-reliability assemblies. |
| MSL Level 1 (J-STD-020) | Allows unlimited floor life and reflow up to 260 °C peak - simplifies SMT manufacturing without baking or special handling. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns response), improving protection fidelity for sensitive CMOS inputs. |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Protection |
|---|---|

Use Scenario: ESD and surge protection for analog sensor outputs (e.g., temperature, pressure) connected to ADC inputs in smart home hubs and wearables. IC Role / Device Role / Timing Role: Low-capacitance unidirectional suppressor on signal line, grounded via shortest path to minimize parasitic inductance. Use Value: Glass-passivated junction delivers <1 ns response and minimal capacitance - preserving signal bandwidth up to 100 MHz without distortion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A-E3/52 (Vishay) | Higher 600 W PPPM, SMB (DO-214AA) package, 130 V VWM, 219 V VC at 2.7 A | Better suited for higher-energy surges; larger footprint requires PCB layout change | Select when system-level surge testing exceeds IEC 61000-4-5 Level 4 and space permits SMB package. |
| 1.5SMC130A (ON Semiconductor) | Same 130 V VWM, 179 V VC, but SMC (DO-214AB) package, 400 W PPPM, non-AEC-Q101 | Lacks automotive qualification; suitable for commercial/industrial use only | Choose for cost-sensitive non-automotive designs where AEC-Q101 is not mandated. |
Compared with P4SMA130AHM3/I, SMBJ130A-E3/52 offers greater surge margin but requires board redesign, while 1.5SMC130A matches key electrical specs but omits AEC-Q101 validation - making P4SMA130AHM3/I the optimal choice for space-constrained, automotive-qualified 12–24 V protection.

FAQ
What is the clamping voltage of the P4SMA130AHM3/I under a 10/1000 µs surge?
The P4SMA130AHM3/I has a maximum clamping voltage (VC) of 179 V at 1.7 A peak pulse current with a 10/1000 µs waveform. This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring downstream components like MOSFETs or microcontrollers remain within their absolute maximum ratings. The P4SMA130AHM3/I achieves this clamping with low incremental surge resistance and sub-nanosecond response.
Is the P4SMA130AHM3/I qualified for automotive applications?
Yes, the P4SMA130AHM3/I is AEC-Q101 qualified, as indicated by the "HM3" suffix (halogen-free, RoHS-compliant, and AEC-Q101 qualified). It is validated for use in automotive environments including body control modules, infotainment power rails, and sensor interfaces where reliability under thermal cycling, humidity, and mechanical shock is mandatory. The P4SMA130AHM3/I also meets JESD201 Class 2 whisker resistance and MSL Level 1 reflow requirements.
What does the "HM3" suffix mean in P4SMA130AHM3/I?
The "HM3" suffix in P4SMA130AHM3/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. Specifically, "H" indicates halogen-free molding compound, "M" confirms RoHS compliance, and "3" signifies JESD201 Class 2 whisker resistance. The trailing "I" specifies 7500-unit reel packaging on 13-inch diameter tape. This suffix ensures the P4SMA130AHM3/I meets stringent environmental and reliability standards for automotive and industrial deployment.
How does the P4SMA130AHM3/I compare to bidirectional TVS diodes?
The P4SMA130AHM3/I is unidirectional and intended for DC circuits where only positive-going transients require suppression - such as 12 V or 24 V power rails. Unlike bidirectional variants (e.g., P4SMA130CA), it blocks reverse voltage beyond its forward drop (~3.5 V at 25 A), making it unsuitable for AC or dual-polarity signal lines. Its design prioritizes tighter VBR tolerance and lower leakage in DC applications, whereas bidirectional types provide symmetric clamping for AC-coupled or floating signals.
What is the thermal resistance of the P4SMA130AHM3/I, and how does it affect layout?
The P4SMA130AHM3/I has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value guides PCB layout: reducing pad size increases thermal impedance and risks exceeding the 150 °C max junction temperature during repetitive surges. For sustained operation near rated PPPM, designers must maintain minimum copper area and consider thermal vias - a key constraint addressed in the P4SMA130AHM3/I's mechanical data and derating curves.
