Product details
Overview
P4SMA130CAHE3/61 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 or 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 lines.
For engineers reviewing the P4SMA130CAHE3/61 datasheet, P4SMA130CAHE3/61 pinout, P4SMA130CAHE3/61 application, or P4SMA130CAHE3/61 equivalent, this device delivers AEC-Q101 qualified transient protection with low incremental surge resistance, fast response time, and MSL Level 1 moisture sensitivity - critical for automotive-grade board-level ESD and surge hardening.
Technical Context
The P4SMA130CAHE3/61 operates bidirectionally with symmetrical clamping behavior in both polarities, enabling use on AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<1 µA at VWM), while thermal resistance (RθJA = 120 °C/W) supports operation up to +150 °C junction temperature under defined PCB pad layout.
It complies with IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and ISO 7637-2 (automotive surge) when applied with appropriate series impedance. The device's 10/1000 µs waveform rating reflects standardized surge immunity testing, and its 3.3 W steady-state power dissipation (PD) defines continuous thermal limits under DC bias conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff Voltage) | 111 V - Maximum continuous reverse voltage before significant conduction begins; sets 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 - Peak voltage seen by protected circuit during 10/1000 µs surge; defines worst-case stress level. |
| PPPM (Peak Pulse Power) | 400 W - Sustained energy absorption capability for standardized 10/1000 µs surge; derates above 25 °C ambient. |

Applications
| Automotive Sensor Interface Protection | Industrial PLC Analog Input Protection |
|---|---|
Use Scenario: Protecting CAN, LIN, or analog sensor lines (e.g., pressure, temperature) in engine bay or chassis modules from ISO 7637-2 induced surges and ESD events. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed across signal pair or signal-to-ground to limit transient voltage before it reaches MCU ADC or transceiver inputs. Use Value: Prevents latch-up or permanent damage to automotive-grade microcontrollers and signal conditioners during battery disconnect/load dump events. |
Use Scenario: Safeguarding 4–20 mA or 0–10 V analog input channels in programmable logic controllers against field wiring surges and ground loop transients. IC Role / Device Role / Timing Role: Standoff-clamp TVS connected between input terminal and system ground to shunt surge energy away from precision op-amps and ADC front-ends. Use Value: Maintains measurement accuracy and avoids spurious trips by limiting transient overvoltage to ≤179 V during 1.7 A surges. |
| Telecom Line Card Surge Protection | Consumer Device USB/DisplayPort ESD Hardening |
Use Scenario: Secondary protection on telecom line cards handling T1/E1 or xDSL signals exposed to lightning-induced surges on outside plant wiring. IC Role / Device Role / Timing Role: Coordinated clamping device downstream of gas discharge tube (GDT) primary protectors to handle residual fast-rising transients. Use Value: Provides sub-200 V clamping within nanoseconds, ensuring compliance with GR-1089-CORE and ITU-T K.20/K.21 immunity requirements. |
Use Scenario: Board-level ESD protection for USB 2.0, HDMI, or DisplayPort connectors in laptops, monitors, and docking stations. IC Role / Device Role / Timing Role: Low-capacitance bidirectional TVS placed directly at connector pins to divert IEC 61000-4-2 ±8 kV contact discharges. Use Value: Limits ESD-induced voltage to <180 V at 30 A peak, preventing data corruption or PHY IC damage without signal integrity impact. |
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/VBR/VC specs but in larger SMB (DO-214AA) package; 600 W PPPM rating; RθJA = 80 °C/W. | Better thermal performance and higher surge rating; requires larger PCB footprint and different pad layout. | Select when higher surge margin or improved thermal dissipation is required and board space permits SMB footprint. |
| 1.5KE130CA | Through-hole DO-201 package; same 130 V nominal rating; 1500 W PPPM; higher leakage (5 µA max at VWM). | Designed for legacy through-hole assembly or high-energy surge zones; not suitable for automated SMT production. | Choose only for prototyping, repair, or applications where manual assembly or extreme single-event energy absorption is prioritized over size and automation. |
Compared with SMBJ130CA and 1.5KE130CA, the P4SMA130CAHE3/61 offers optimal balance of compact SMA footprint, AEC-Q101 qualification, and 400 W surge capability - making it the preferred choice for space-constrained automotive and industrial SMT designs requiring certified reliability.

FAQ
What does the "CA" suffix indicate in P4SMA130CAHE3/61?
The "CA" suffix denotes a bidirectional configuration - meaning the P4SMA130CAHE3/61 provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., P4SMA130A), the P4SMA130CAHE3/61 has no polarity marking and functions identically in either orientation, simplifying layout for AC-coupled or floating signal lines.
Is P4SMA130CAHE3/61 suitable for automotive applications?
Yes - the P4SMA130CAHE3/61 carries AEC-Q101 qualification, confirming its suitability for automotive electronics including engine control, body modules, and ADAS sensors. Its construction (glass-passivated junction, MSL Level 1, -65 °C to +150 °C operation), combined with documented surge performance per ISO 7637-2, makes the P4SMA130CAHE3/61 a validated choice for under-hood and chassis-mounted systems.
What is the maximum clamping voltage of P4SMA130CAHE3/61 under surge conditions?
The P4SMA130CAHE3/61 exhibits a maximum clamping voltage (VC) of 179 V when subjected to its rated peak pulse current (IPPM) of 1.7 A using the standard 10/1000 µs waveform. This value represents the highest voltage imposed on the protected circuit during transient suppression and is measured at the device terminals under specified test conditions.
How does the SMA (DO-214AC) package of P4SMA130CAHE3/61 compare to SMB or SMC packages?
The SMA package of the P4SMA130CAHE3/61 measures 4.50 mm × 2.79 mm and offers a compact footprint ideal for dense PCB layouts, though with higher thermal resistance (RθJA = 120 °C/W) than SMB (80 °C/W) or SMC (50 °C/W). Its 400 W PPPM rating is optimized for typical automotive and industrial surge profiles, whereas larger packages support higher energy handling at the cost of board area.
Does P4SMA130CAHE3/61 require a heatsink for normal operation?
No - the P4SMA130CAHE3/61 is designed for surface-mount operation without external heatsinking. Its thermal performance relies on adherence to the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad layout per terminal, which provides sufficient heat spreading. The 3.3 W steady-state power dissipation (PD) and 120 °C/W junction-to-ambient resistance assume this layout; additional copper or internal planes may further improve thermal margin.
