Product details
Overview
P4SMA130CAHM3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in SMA (DO-214AC) package, designed for clamping voltage transients on signal and power lines. It features a 111 V standoff voltage (VWM), 124–137 V breakdown voltage (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 - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial systems.
For engineers reviewing the P4SMA130CAHM3_A/H datasheet, P4SMA130CAHM3_A/H pinout, P4SMA130CAHM3_A/H application, or P4SMA130CAHM3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, MSL Level 1 moisture sensitivity, halogen-free RoHS compliance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a voltage-clamping protector with symmetrical avalanche behavior in both directions, enabling suppression of positive and negative transients without polarity dependency. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 µA at VWM), while the low incremental surge resistance supports fast energy diversion during ESD or lightning-induced surges.
The P4SMA130CAHM3_A/H is rated for 150 °C maximum junction temperature and derates linearly above 25 °C ambient per Figure 2; thermal resistance is 120 °C/W junction-to-ambient (on recommended pad layout) and 30 °C/W junction-to-lead. It meets UL 497B recognition (QVGQ2) and JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff Voltage) | 111 V - Maximum continuous reverse working 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 overvoltage events |
| VC (Clamping Voltage) | 179 V at 1.7 A (10/1000 µs) - Peak voltage seen by protected circuit during worst-case transient; limits stress on downstream components |
| PPPM (Peak Pulse Power) | 400 W - Sustained transient energy handling capacity under standard 10/1000 µs waveform; validated at TA = 25 °C |
| PD (Steady-State Power) | 3.3 W - Continuous power dissipation limit on infinite heatsink at 50 °C ambient; guides thermal design for sustained leakage conditions |
| TJ max. | 150 °C - Maximum allowable junction temperature; sets upper boundary for thermal management in enclosed or high-ambient environments |
| Package | SMA (DO-214AC) - Standardized surface-mount outline with 5.0 mm × 5.0 mm copper pad requirement; compatible with J-STD-020 reflow profiles |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA | Higher 600 W PPPM rating; larger SMB (DO-214AA) package; 124–137 V VBR same range | Better suited for higher-energy surges where board space allows larger footprint | Select when 600 W surge margin is required and PCB layout accommodates 2.54 mm lead pitch increase |
| 1.5KE130CA | Through-hole TO-218 package; 1500 W PPPM; same 111 V VWM and 179 V VC | Designed for legacy through-hole assembly or high-power industrial mains protection | Choose only if through-hole mounting is mandated or if system-level surge testing exceeds 400 W capability |
Compared with SMBJ130CA and 1.5KE130CA, the P4SMA130CAHM3_A/H offers optimal balance of AEC-Q101 qualification, SMT scalability, and 400 W protection in the smallest standardized surface-mount TVS outline - making it preferred for space-constrained automotive and portable industrial designs.

FAQ
What does the "CA" suffix indicate in P4SMA130CAHM3_A/H?
The "CA" suffix denotes a bidirectional configuration - meaning the P4SMA130CAHM3_A/H provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., P4SMA130A), it has no polarity marking and functions identically regardless of terminal orientation, making it ideal for AC-coupled or differential signal lines.
Is P4SMA130CAHM3_A/H qualified for automotive applications?
Yes, P4SMA130CAHM3_A/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code structure ("HM3" = halogen-free + AEC-Q101) and documentation revision 09-Jan-2024. It undergoes stress testing for temperature cycling, high-temperature reverse bias, and ESD per AEC-Q101 Rev D, supporting deployment in engine control units, ADAS sensors, and body electronics.
What is the maximum clamping voltage of P4SMA130CAHM3_A/H under surge conditions?
The maximum clamping voltage (VC) of P4SMA130CAHM3_A/H is 179 V at 1.7 A peak pulse current with a 10/1000 µs waveform. This value is measured per Figure 1 and Table on page 2 of Vishay document 88367 and represents the highest voltage imposed on the protected circuit during standardized surge events.
Does P4SMA130CAHM3_A/H require special PCB layout considerations?
Yes - P4SMA130CAHM3_A/H must be mounted on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve its rated 400 W peak pulse power. Short, wide traces to ground/power planes and placement adjacent to protected ICs or connectors minimize inductance and ensure effective clamping performance per Vishay's thermal and surge test conditions.
How does the "HM3" suffix differ from "HE3" in P4SMA130CAHM3_A/H?
The "HM3" suffix indicates halogen-free, RoHS-compliant construction with AEC-Q101 qualification, whereas "HE3" denotes RoHS-compliant and AEC-Q101 qualified but not halogen-free. Both meet JESD201 Class 2 whisker resistance and MSL Level 1, but P4SMA130CAHM3_A/H satisfies stricter environmental mandates such as IEC 61249-2-21 for halogen-free printed wiring boards.
