Product details
Overview
P4SMA130CAHE3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in the P4SMA series, designed for clamping voltage transients on signal and power lines. It features a 130 V standoff voltage (VWM), 149 V minimum breakdown voltage (VBR), 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 automotive sensor interfaces and industrial I/O lines against ESD and inductive switching surges.
For engineers reviewing the P4SMA130CAHE3_A/H datasheet, P4SMA130CAHE3_A/H pinout, P4SMA130CAHE3_A/H application, or P4SMA130CAHE3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, SMA (DO-214AC) package compatibility, and thermal performance under repetitive surge conditions in automotive-grade designs.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 µA at VWM), while the low incremental surge resistance supports consistent clamping across surge events.
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 thermal resistance (RθJA = 120 °C/W) and 3.3 W steady-state power dissipation define layout requirements for copper pad area and board-level heat sinking in high-reliability applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 111 V - Maximum continuous reverse voltage before clamping begins; defines operating margin for 12 V–48 V automotive and industrial bus lines. |
| VBR (Breakdown Voltage) | 124–137 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during transient events above nominal system voltage. |
| VC (Clamping Voltage) | 179 V at IPPM = 1.7 A - Peak voltage seen by protected circuit during 10/1000 µs surge; determines safe overvoltage margin for downstream ICs. |
| PPPM (Peak Pulse Power) | 400 W - Sustained energy absorption capability under standardized 10/1000 µs waveform; validates robustness against lightning-induced surges. |
| ID (Reverse Leakage) | <1 µA at VWM - Minimal standby current draw; critical for low-power sensor nodes and battery-backed systems. |
| TJ max. | 150 °C - Maximum junction temperature rating; enables operation in under-hood automotive environments and sealed industrial enclosures. |
| AEC-Q101 Qualified | Yes - Validated for automotive electronics per stress test requirements including HTOL, TCT, and ESD; supports PPAP documentation. |

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 | Same VWM (111 V) and VC (179 V), but SMB package (DO-214AA); 600 W PPPM rating. | Higher power handling, larger footprint; better suited for 24 V industrial power rails than compact sensor nodes. | Select when higher surge margin is required and PCB space allows larger SMB outline. |

FAQ
What is the clamping voltage of P4SMA130CAHE3_A/H at its rated peak pulse current?
The P4SMA130CAHE3_A/H has a maximum clamping voltage (VC) of 179 V at a peak pulse current (IPPM) of 1.7 A using the 10/1000 µs waveform. This value is measured under standardized test conditions with 0.2" × 0.2" copper pads and confirms the device's ability to limit transient overvoltage to a safe level for downstream components. The P4SMA130CAHE3_A/H maintains this clamping performance across its specified operating temperature range.
Is P4SMA130CAHE3_A/H suitable for automotive applications?
Yes, the P4SMA130CAHE3_A/H is AEC-Q101 qualified and carries the HE3 suffix indicating automotive-grade qualification. It undergoes stress testing for high-temperature operating life, temperature cycling, and ESD robustness per automotive standards. The P4SMA130CAHE3_A/H is commonly used in engine control units, ADAS camera modules, and body electronics where reliable transient suppression is mandatory.
What does the "CA" suffix indicate in P4SMA130CAHE3_A/H?
The "CA" suffix in P4SMA130CAHE3_A/H denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities, with identical VBR, VC, and IPPM characteristics for positive and negative surges. This eliminates polarity concerns during layout and simplifies protection of AC-coupled or differential signal lines. The P4SMA130CAHE3_A/H has no cathode band marking, distinguishing it from unidirectional variants.
What is the thermal resistance of P4SMA130CAHE3_A/H, and how does it affect PCB layout?
The P4SMA130CAHE3_A/H 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. To maintain safe junction temperatures under sustained power dissipation, designers must provide adequate copper area and avoid excessive trace length. The P4SMA130CAHE3_A/H thermal performance is optimized for standard FR-4 boards with minimal additional heatsinking.
How does P4SMA130CAHE3_A/H compare to unidirectional P4SMA130AHE3_A/H in terms of application use cases?
The P4SMA130CAHE3_A/H is bidirectional and used where voltage transients can occur in either polarity - such as RS-485 buses, CAN FD lines, or AC-coupled audio paths. In contrast, the unidirectional P4SMA130AHE3_A/H includes a cathode band and is intended for DC-biased lines like power supplies or single-ended digital I/O. The P4SMA130CAHE3_A/H cannot replace unidirectional types in circuits requiring forward conduction or DC blocking functionality.
