Product details
Overview
P4SMA110CAHE3/61 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in the P4SMA series, designed for clamping voltage transients on signal or power lines. It features a 110 V standoff voltage (VWM), 125 V maximum clamping voltage (VC) at 2.0 A peak pulse current (IPPM), and 400 W peak pulse power capability with a 10/1000 µs waveform - suitable for protecting MOSFETs and sensor signal lines in industrial control systems.
For engineers reviewing the P4SMA110CAHE3/61 datasheet, P4SMA110CAHE3/61 pinout, P4SMA110CAHE3/61 application, or P4SMA110CAHE3/61 equivalent, key selection criteria include bidirectional clamping behavior, AEC-Q101 qualification, SMA (DO-214AC) package compatibility, and thermal resistance (RθJA = 120 °C/W) under standard PCB pad layout.
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 concerns. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at VWM), while the 10/1000 µs surge rating reflects standardized lightning and inductive-switching transient immunity.
The device is rated for continuous power dissipation of 3.3 W at 50 °C ambient on an infinite heatsink, with junction temperature limited to 150 °C. Derating above 25 °C follows a defined curve (Fig. 2), and thermal resistance from junction-to-ambient (120 °C/W) assumes mounting on 0.2" × 0.2" copper pads per terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 94.0 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 105–116 V at 1.0 mA - Confirmed voltage range where device transitions into avalanche conduction; tight tolerance supports predictable protection threshold. |
| VC (Clamping Voltage) | 152 V at IPPM = 2.0 A - Peak voltage seen across protected circuit during 10/1000 µs transient; critical for ensuring downstream ICs remain within absolute maximum ratings. |
| PPPM (Peak Pulse Power) | 400 W - Sustained energy-handling capacity for single transients; derates to 300 W above 91 V per spec note. |
| ID (Reverse Leakage) | <1.0 µA at VWM - Minimal standby current draw; preserves signal integrity and battery life in low-power sensor interfaces. |
| TJ max. | +150 °C - Maximum allowable junction temperature; enables operation in under-hood automotive or high-temperature industrial environments. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock; required for ECUs and ADAS sensor modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA | Same VWM (94 V), higher VC (187 V at 2.2 A), SMB package (DO-214AA) - 30 % larger footprint, 20 % higher RθJA. | Less space-constrained designs; lower power density but better thermal margin on minimal copper. | Select when board layout permits larger package and higher clamping voltage is acceptable for protected ICs. |
| 1.5KE110CA | Through-hole TO-204AE (DO-41); same VWM/VC specs but 1500 W PPPM rating and 50 A IFSM - not surface-mountable. | Legacy or high-energy industrial systems where manual assembly or extreme surge robustness is prioritized over automation. | Choose only for through-hole production or where >400 W surge energy must be absorbed without cascading failure. |
Compared with SMBJ110CA and 1.5KE110CA, P4SMA110CAHE3/61 delivers optimal balance of compact SMA footprint, AEC-Q101 compliance, and precise 152 V clamping - making it preferred for automated SMT lines targeting automotive and space-constrained industrial modules.

FAQ
What is the clamping voltage of P4SMA110CAHE3/61 at its rated peak pulse current?
The P4SMA110CAHE3/61 has a maximum clamping voltage (VC) of 152 V at a peak pulse current (IPPM) of 2.0 A with a 10/1000 µs waveform. This value is measured under standard test conditions (TA = 25 °C, mounted on 0.2" × 0.2" copper pads) and represents the upper voltage limit imposed on protected circuitry during transient events - a critical parameter for ensuring downstream ICs remain within their absolute maximum ratings.
Is P4SMA110CAHE3/61 suitable for automotive applications?
Yes, P4SMA110CAHE3/61 is AEC-Q101 qualified and carries the HE3 suffix indicating RoHS-compliant and automotive-grade construction. It meets rigorous stress tests including temperature cycling, humidity bias, and mechanical shock - making it appropriate for engine control units, body electronics, and ADAS sensor modules where reliability under thermal and vibration stress is mandatory.
What does the "CA" suffix mean in P4SMA110CAHE3/61?
The "CA" suffix in P4SMA110CAHE3/61 denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both forward and reverse directions. Unlike unidirectional variants (e.g., P4SMA110A), this version has no cathode marking and is used where polarity cannot be guaranteed, such as across AC signal lines, differential buses, or floating grounds.
What is the standoff voltage (VWM) of P4SMA110CAHE3/61, and why does it differ from the breakdown voltage?
The standoff voltage (VWM) of P4SMA110CAHE3/61 is 94.0 V - the maximum DC or RMS voltage that can be continuously applied without triggering clamping. It is intentionally lower than the minimum breakdown voltage (VBR = 105 V) to provide a safety margin, ensuring reliable operation under normal conditions while still responding rapidly to transients exceeding the VWM threshold.
Can P4SMA110CAHE3/61 be used in place of a unidirectional TVS like P4SMA110A?
No - P4SMA110CAHE3/61 is bidirectional and lacks polarity marking, whereas P4SMA110A is unidirectional with a defined cathode band. Substituting them requires verifying circuit topology: P4SMA110CAHE3/61 is appropriate for AC-coupled or differential paths, while P4SMA110A suits DC rails referenced to ground. Using the wrong type may result in unintended conduction or ineffective protection.
