Product details
Overview
P4SMA110CA-M3/61 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, rated for 110 V standoff voltage (VWM), 152 V maximum clamping voltage (VC) at 2.0 A peak pulse current (IPPM), and 400 W peak pulse power (10/1000 µs waveform). It protects signal lines and power rails in automotive sensor units, industrial I/O interfaces, and telecom line cards against ESD and inductive switching transients.
For engineers reviewing the P4SMA110CA-M3/61 datasheet, P4SMA110CA-M3/61 pinout, P4SMA110CA-M3/61 application, or P4SMA110CA-M3/61 equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, thermal derating curves, AEC-Q101 qualification status, and halogen-free RoHS compliance per M3 suffix - all critical for automotive-grade surge protection design-in.
Technical Context
The P4SMA110CA-M3/61 operates as a symmetrical bidirectional TVS, with identical breakdown (VBR min/max = 105–116 V) and clamping characteristics in both polarities. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, ensuring robust transient suppression without latch-up or degradation under repetitive 10/1000 µs pulses at 0.01% duty cycle.
Thermally, it features RθJA = 120 °C/W and RθJL = 30 °C/W, with maximum junction temperature of +150 °C and operation down to –65 °C. The device is qualified to AEC-Q101 (via HM3 suffix variant), meets UL 94 V-0 flammability, and is rated for 40 A non-repetitive forward surge (IFSM) in unidirectional mode - though P4SMA110CA-M3/61 itself is bidirectional and has no polarity marking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 110 V - Maximum continuous reverse voltage before conduction begins; defines operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 105–116 V at 1 mA - Confirmed symmetric breakdown in both directions; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 152 V at IPPM = 2.0 A (10/1000 µs) - Peak voltage seen by protected circuit during worst-case transient; limits stress on downstream ICs. |
| PPPM (Peak Pulse Power) | 400 W - Sustained energy absorption capability under standard lightning-surge waveform; derates above 25 °C per Fig. 2. |
| ID (Reverse Leakage) | 1.0 µA max at VWM - Minimal standby current leakage; preserves signal integrity and battery life in always-on systems. |
| TJ max | +150 °C - Enables reliable operation in under-hood automotive or high-ambient industrial environments. |
| Package | SMA (DO-214AC) - Surface-mount footprint compatible with automated assembly; 0.2" × 0.2" copper pad layout required for full 400 W rating. |
Pinout & Package
Package: SMA (DO-214AC), molded plastic case with matte tin-plated leads, UL 94 V-0 rated, MSL Level 1 (260 °C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional terminal pair | No polarity marking; terminals interchangeable - enables single-component protection of AC-coupled or differential signal lines. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-to-ground) when properly laid out with 0.2" × 0.2" pads. |
| AEC-Q101 qualified (HM3 variant) | Validated for automotive applications including engine control modules and ADAS sensor interfaces requiring long-term reliability. |
| Halogen-free & RoHS-compliant (M3 suffix) | Meets environmental compliance mandates for EU, China RoHS, and JIS C 0950 without compromising surge performance. |
| Low clamping ratio (VC/VBR ≈ 1.38) | Minimizes overvoltage overshoot during fast transients - critical for protecting 3.3 V or 5 V logic-level interfaces. |
| Fast response time (<1 ns) | Clamps before sensitive CMOS inputs can be damaged by ESD or inductive kickback; no external triggering required. |
Applications
| Automotive Sensor Protection | Industrial RS-485 Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA | Same VWM (110 V) and VC (152 V), but SMB package (DO-214AA); 600 W PPPM rating; higher thermal mass. | Better suited for higher-energy surges where PCB space allows larger footprint; not drop-in compatible due to different pad layout. | Select SMBJ110CA when surge energy exceeds 400 W or board layout permits wider 0.3" × 0.3" pads. |
| 1.5KE110CA | Through-hole DO-201AE package; same VWM/VC specs; 1500 W PPPM; higher IFSM (100 A); no AEC-Q101 option. | Used in legacy industrial power supplies where manual assembly or high-reliability through-hole mounting is required. | Choose 1.5KE110CA only for prototyping or repair scenarios where surface-mount constraints do not apply. |
Compared with SMBJ110CA and 1.5KE110CA, the P4SMA110CA-M3/61 offers optimal balance of compact SMA footprint, AEC-Q101 qualification, halogen-free compliance, and verified 400 W surge handling - making it the preferred choice for volume automotive and space-constrained industrial designs.

FAQ
What is the clamping voltage of P4SMA110CA-M3/61 at its rated peak pulse current?
The P4SMA110CA-M3/61 has a maximum clamping voltage (VC) of 152 V when subjected to a 10/1000 µs waveform at 2.0 A peak pulse current (IPPM). 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 circuits during surge events. The P4SMA110CA-M3/61 maintains this clamping performance symmetrically in both directions due to its bidirectional construction.
Is P4SMA110CA-M3/61 qualified for automotive applications?
The P4SMA110CA-M3/61 itself carries the M3 suffix (halogen-free, RoHS-compliant commercial grade), not the HM3 suffix required for AEC-Q101 qualification. However, the P4SMA110CA-HM3/61 variant is explicitly AEC-Q101 qualified per the Vishay datasheet revision 09-Jan-2024. Engineers selecting P4SMA110CA-M3/61 for automotive use must verify system-level qualification requirements - the P4SMA110CA-M3/61 shares identical electrical specs and package but lacks formal automotive stress testing documentation.
What does the "CA" suffix indicate in P4SMA110CA-M3/61?
The "CA" suffix in P4SMA110CA-M3/61 denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both forward and reverse directions, with identical VBR, VC, and IPPM characteristics across polarity. Unlike unidirectional variants (e.g., P4SMA110A), the P4SMA110CA-M3/61 has no cathode band marking and is used where AC signals, differential buses, or polarity-agnostic protection is required. This is confirmed in Vishay's "DEVICES FOR BIDIRECTION APPLICATIONS" section.
What is the thermal resistance of P4SMA110CA-M3/61, and how does it affect layout?
The P4SMA110CA-M3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W and junction-to-lead resistance (RθJL) of 30 °C/W. To achieve its full 400 W peak pulse power rating, the device must be mounted on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal - smaller pads cause thermal derating per Figure 2 in the datasheet. Layouts using the P4SMA110CA-M3/61 should avoid narrow traces or isolated pads that impede heat dissipation during repetitive surge events.
How does P4SMA110CA-M3/61 compare to unidirectional P4SMA110A-M3/61 in terms of leakage and breakdown?
The P4SMA110CA-M3/61 and P4SMA110A-M3/61 share identical VWM (110 V), VBR (105–116 V), and ID (1.0 µA max) specifications - confirming matched electrical thresholds. However, the P4SMA110A-M3/61 is unidirectional with cathode marking and conducts only in reverse bias, while the P4SMA110CA-M3/61 conducts identically in both directions. Both exhibit the same 152 V clamping voltage at 2.0 A, but only the CA version supports AC or differential signal protection without polarity concerns. The P4SMA110CA-M3/61 is therefore preferred for RS-485, CAN, and Ethernet applications.
