Product details
Overview
P4SMA110A-E3/61 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on power and signal lines. It features a 105 V to 116 V breakdown voltage (VBR), 94.0 V maximum standoff voltage (VWM), 152 V clamping voltage at 2.0 A peak pulse current, 400 W peak pulse power (10/1000 µs), and AEC-Q101 qualification for automotive applications.
For engineers reviewing the P4SMA110A-E3/61 datasheet, P4SMA110A-E3/61 pinout, P4SMA110A-E3/61 application, or P4SMA110A-E3/61 equivalent, this device serves as a robust, RoHS-compliant transient protector for 12 V–48 V DC systems where fast response (<1 ns), low clamping ratio, and stable thermal performance up to 150 °C junction temperature are required.
Technical Context
The P4SMA110A-E3/61 operates as a unidirectional avalanche diode with glass-passivated junction, enabling precise reverse-breakdown behavior under transient overvoltage events. Its 10/1000 µs waveform rating of 400 W (derated to 300 W above 91 V) and 2.0 A peak pulse current reflect its capability to absorb repetitive surge energy without degradation when mounted on 5.0 mm × 5.0 mm copper pads.
Thermal design is supported by RθJA = 120 °C/W and RθJL = 30 °C/W, allowing reliable operation at TJ up to +150 °C. The cathode-band polarity marking ensures correct PCB orientation, and MSL Level 1 compliance confirms suitability for standard reflow processes with peak temperature up to 260 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V to 116 V at 1.0 mA test current - defines precise avalanche initiation threshold for overvoltage protection |
| VWM | 94.0 V maximum - ensures no conduction during normal 12 V–48 V system operation |
| VC @ IPPM | 152 V at 2.0 A - clamping voltage limits downstream IC stress during ESD or load-switching transients |
| PPPM | 400 W (10/1000 µs) - delivers high-energy transient suppression without thermal runaway |
| IFSM | 40 A (8.3 ms half-sine) - supports robust handling of non-repetitive forward surge events |
| TJ max. | +150 °C - enables use in under-hood automotive and industrial environments |
| Package | SMA (DO-214AC) - standardized SMT footprint compatible with automated placement and IPC-7351B land patterns |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A | Same VBR range (105–116 V), but SMB package (DO-214AA); 600 W PPPM, higher IPPM (3.3 A), larger footprint (4.57 mm × 3.94 mm) | Better suited for higher-energy surges; requires larger PCB area and different pad layout | Select when >400 W surge margin is needed and board space allows SMB footprint |
| 1.5SMC110A | Same VBR and VWM, but SMC (DO-214AB) package; 1500 W PPPM, 13.3 A IPPM, 7.11 mm × 6.22 mm body | Designed for industrial mains-level surge immunity (IEC 61000-4-5 Level 4); not AEC-Q101 qualified | Choose for non-automotive, high-energy AC/DC front-end protection where AEC-Q101 is not required |
Compared with SMBJ110A and 1.5SMC110A, the P4SMA110A-E3/61 offers optimal balance of compact SMA footprint, AEC-Q101 qualification, and sufficient 400 W surge rating for 24 V/48 V automotive and industrial subsystems-without requiring PCB redesign or sacrificing automotive reliability validation.

FAQ
What is the breakdown voltage tolerance for P4SMA110A-E3/61?
The P4SMA110A-E3/61 has a specified breakdown voltage (VBR) range of 105 V to 116 V at 1.0 mA test current, corresponding to a ±5 % tolerance around the nominal 110 V rating. This tight tolerance ensures consistent clamping behavior across production lots and supports reliable overvoltage threshold design in safety-critical circuits.
Is P4SMA110A-E3/61 suitable for automotive applications?
Yes, the P4SMA110A-E3/61 is AEC-Q101 qualified and explicitly listed in Vishay's automotive ordering codes (HE3/HM3 variants). Its construction-including glass-passivated junction, MSL Level 1 reflow compatibility, and operation up to +150 °C junction temperature-meets automotive environmental and reliability requirements for under-hood and body electronics.
What is the maximum clamping voltage of P4SMA110A-E3/61 under surge conditions?
The P4SMA110A-E3/61 exhibits a maximum clamping voltage (VC) of 152 V at 2.0 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value is guaranteed across temperature and ensures protected circuitry remains below critical overvoltage thresholds during transient events.
Does P4SMA110A-E3/61 have polarity marking, and how is it oriented on PCB?
Yes, the P4SMA110A-E3/61 uses a cathode band marking on the SMA (DO-214AC) package body. During PCB layout, the banded end must be connected to the line being protected (e.g., 24 V rail), while the unmarked end connects to ground-ensuring correct unidirectional conduction during overvoltage events.
What is the thermal resistance of P4SMA110A-E3/61, and how does it affect layout?
The P4SMA110A-E3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W and junction-to-lead (RθJL) of 30 °C/W. To maintain safe operation, PCB layout must use minimum 5.0 mm × 5.0 mm copper pads per terminal, as specified in Vishay's mounting recommendations-otherwise derating of power capability is required.
