Product details
Overview
P4SMA130AHM3/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for robust overvoltage protection of sensitive electronics. It features a 111 V standoff voltage (VWM), 124–137 V breakdown range (VBR at 1 mA), 179 V maximum clamping voltage (VC) at 1.7 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - suitable for protecting MOSFETs, ICs, and sensor signal lines in industrial and automotive power supplies.
For engineers reviewing the P4SMA130AHM3/H datasheet, P4SMA130AHM3/H pinout, P4SMA130AHM3/H application, or P4SMA130AHM3/H equivalent, this device delivers AEC-Q101 qualification, halogen-free RoHS compliance, MSL Level 1 moisture sensitivity, and verified clamping performance under repetitive surge conditions - critical for automotive-grade ESD and load-dump protection design validation.
Technical Context
The P4SMA130AHM3/H operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its specified breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, enabling precise clamping during fast transients (response time < 1 ns).
Thermally, it supports operation from –65 °C to +150 °C junction temperature, with RθJA = 120 °C/W and RθJL = 30 °C/W. Derating above 25 °C ambient follows Fig. 2 in the datasheet, maintaining 300 W peak power capability above 91 V per JEDEC JESD22-A114.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff 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 - Confirmed avalanche onset range; ensures predictable turn-on during transients without premature leakage. |
| VC (Clamping Voltage) | 179 V at IPPM = 1.7 A - Peak voltage seen by protected circuit during 10/1000 µs surge; limits stress on downstream components. |
| PPPM (Peak Pulse Power) | 400 W - Sustains single 10/1000 µs surges; derates to 300 W above 91 V per datasheet note (1). |
| IFSM (Surge Current) | 40 A - Withstands 8.3 ms half-sine surge (unidirectional only); validates robustness against inductive switch-off events. |
| TJ max. | +150 °C - Enables reliable operation in under-hood automotive environments and high-temperature industrial enclosures. |
| AEC-Q101 Qualified | Yes - Validated for automotive electronic modules requiring stress-tested reliability per JESD22 and AEC failure mechanisms. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002 and JESD22-B102. Cathode indicated by band; polarity-critical for unidirectional operation.

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) | Same VWM/VBR/VC specs but in larger SMB (DO-214AA) package; 600 W PPPM; RθJA = 75 °C/W. | Better thermal dissipation for high-duty-cycle surges; requires 30% more PCB area than SMA. | Select when board layout allows larger footprint and higher average surge energy must be absorbed. |
| 1.5KE130A (ON Semiconductor) | Through-hole DO-201 package; identical 111 V VWM, 124–137 V VBR, 179 V VC; 1500 W PPPM but slower response due to higher junction capacitance. | Not suitable for high-frequency signal lines; intended for bulk power rail protection only. | Choose only for legacy through-hole designs where SMT is not feasible and surge repetition rate is low. |
Compared with SMBJ130A-E3/52 and 1.5KE130A, the P4SMA130AHM3/H offers optimal balance of AEC-Q101 qualification, compact SMA footprint, and verified 400 W surge capability - making it preferred for space-constrained automotive and industrial SMT assemblies requiring production traceability and halogen-free compliance.

FAQ
What is the clamping voltage of the P4SMA130AHM3/H under a 10/1000 µs surge?
The P4SMA130AHM3/H has a maximum clamping voltage (VC) of 179 V at a peak pulse current (IPPM) of 1.7 A with a 10/1000 µs waveform. This value is measured per Figure 1 in the Vishay datasheet 88367 and represents the upper limit of voltage imposed on the protected circuit during standardized surge testing.
Is the P4SMA130AHM3/H suitable for automotive applications?
Yes, the P4SMA130AHM3/H is AEC-Q101 qualified (indicated by the HM3 suffix) and halogen-free, meeting stringent automotive reliability requirements for powertrain, body control, and infotainment modules. Its –65 °C to +150 °C operating range and MSL Level 1 rating further validate suitability for under-hood and dashboard environments.
What does the "HM3" suffix mean in P4SMA130AHM3/H?
The "HM3" suffix in P4SMA130AHM3/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. The "H" indicates 7-inch tape-and-reel packaging (1800 units/reel), and "M3" confirms compliance with JESD201 Class 2 whisker resistance and IPC-1752A material declaration standards.
How does the P4SMA130AHM3/H compare to bidirectional TVS diodes like P4SMA130CA?
The P4SMA130AHM3/H is unidirectional and optimized for DC rail protection where polarity is fixed, offering tighter VBR tolerance and lower leakage. In contrast, P4SMA130CA is bidirectional and suited for AC or floating signal lines - but exhibits higher reverse leakage and wider VBR spread. The P4SMA130AHM3/H is not interchangeable with P4SMA130CA without circuit redesign.
What is the thermal resistance of the P4SMA130AHM3/H, and how does it affect layout?
The P4SMA130AHM3/H has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W and junction-to-lead (RθJL) of 30 °C/W. To maintain reliability under repeated surges, PCB layout must use minimum recommended copper pad areas (0.2" × 0.2" per terminal) per datasheet Figure 4; inadequate copper reduces effective power handling and risks thermal runaway.
