Product details
Overview
P4SMA130CAHE3_A/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode 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 (IPPM), and 400 W peak pulse power (10/1000 μs waveform), suitable for protecting automotive sensor interfaces and industrial I/O circuits.
For engineers reviewing the P4SMA130CAHE3_A/I datasheet, P4SMA130CAHE3_A/I pinout, P4SMA130CAHE3_A/I application, or P4SMA130CAHE3_A/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance data, clamping performance under standardized surge waveforms, and direct alternatives for circuit protection design-in.
Technical Context
The P4SMA130CAHE3_A/I operates as a bidirectional avalanche diode, symmetrically clamping transient overvoltages in both polarities without polarity marking. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance, enabling fast response to ESD and lightning-induced surges.
Rated for 150 °C maximum junction temperature and compliant with AEC-Q101 for automotive use, it delivers 400 W peak pulse power (derated to 300 W above 91 V), with thermal resistance of 120 °C/W (junction-to-ambient) and 30 °C/W (junction-to-lead) under defined PCB pad conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 111 V - Maximum continuous reverse voltage before conduction begins; defines operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 124–137 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 179 V at IPPM = 1.7 A (10/1000 μs) - Peak voltage seen by protected circuit during worst-case surge; critical for IC survivability. |
| PPPM (Peak Pulse Power) | 400 W - Sustained energy absorption capability under standard 10/1000 μs waveform; derates to 300 W above 91 V. |
| ID (Reverse Leakage) | 1.0 μA at VWM - Minimal standby current; preserves signal integrity and low-power operation. |
| TJ max. | 150 °C - Enables reliable operation in under-hood automotive and high-temperature industrial environments. |
| 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 plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; meets UL 94 V-0 flammability rating and MSL level 1 (260 °C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |

| Cathode | Current exit terminal in forward bias; common node in bidirectional configuration | Same physical terminal as Anode due to bidirectional symmetry; no band marking on device body. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA | Higher package thermal mass (SMB/DO-214AA); RθJA = 85 °C/W vs. 120 °C/W; same VWM/VBR/VC specs. | Better power handling in sustained surge events; requires larger PCB pad area. | Select when board layout allows larger footprint and higher average power dissipation is needed. |
| 1.5KE130CA | Through-hole TO-204AE (DO-41); 1500 W PPPM rating but slower response due to higher junction capacitance. | Used in legacy designs or where manual assembly is preferred; not suitable for high-speed signal lines. | Choose only for cost-sensitive non-automotive applications where AEC-Q101 and SMT are not required. |
Compared with SMBJ130CA and 1.5KE130CA, the P4SMA130CAHE3_A/I offers AEC-Q101 qualification, SMA package compatibility with automated placement, and optimal balance of clamping voltage, surge capacity, and board space-making it the preferred choice for new automotive and industrial SMT designs requiring validated reliability.

FAQ
What is the clamping voltage of the P4SMA130CAHE3_A/I under a 10/1000 μs surge?
The P4SMA130CAHE3_A/I has a maximum clamping voltage (VC) of 179 V at 1.7 A peak pulse current under the standardized 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88367 and represents the upper voltage limit imposed on protected circuitry during worst-case transient events. The P4SMA130CAHE3_A/I maintains this clamping performance across its qualified temperature range and after repeated surge exposure.
Is the P4SMA130CAHE3_A/I suitable for automotive applications?
Yes, the P4SMA130CAHE3_A/I is AEC-Q101 qualified and specifically designated for automotive use via the "HE3" suffix and revision code "A". It undergoes stress testing for temperature cycling, humidity bias, and mechanical shock per AEC-Q101 requirements. The P4SMA130CAHE3_A/I is deployed in engine control units, ADAS camera modules, and body electronics where robust transient immunity is mandated.
Does the P4SMA130CAHE3_A/I have polarity markings?
No, the P4SMA130CAHE3_A/I is a bidirectional TVS diode and carries no cathode band or polarity marking. Its symmetrical construction allows identical clamping behavior for positive and negative transients, eliminating orientation concerns during automated placement. This distinguishes it from unidirectional variants like P4SMA130A, which feature a visible cathode band.
What is the thermal resistance of the P4SMA130CAHE3_A/I?
The P4SMA130CAHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on 0.2" x 0.2" (5.0 mm x 5.0 mm) copper pads per terminal, and a junction-to-lead resistance (RθJL) of 30 °C/W. These values are specified in the Thermal Characteristics table of Vishay document 88367 and are critical for calculating safe operating temperature margins under sustained power dissipation.
How does the P4SMA130CAHE3_A/I differ from the P4SMA130A variant?
The P4SMA130CAHE3_A/I is bidirectional (denoted by "CA") and AEC-Q101 qualified ("HE3"), whereas the P4SMA130A is unidirectional with no automotive qualification. The "CA" version clamps symmetrically in both directions and lacks a cathode band; the "A" version conducts only in reverse bias and requires correct orientation. Both share identical VWM, VBR, and VC ratings, but only the P4SMA130CAHE3_A/I is approved for automotive under-hood deployment.
