Product details
Overview
P4SMA110A-E3/5A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 110 V breakdown voltage (VBR = 105–116 V at 1 mA), 94.0 V maximum standoff voltage (VWM), and clamps transients to ≤152 V at 2.0 A peak pulse current (10/1000 µs), delivering 400 W peak pulse power capability. It is widely deployed in automotive sensor interfaces and industrial I/O protection circuits.
For engineers reviewing the P4SMA110A-E3/5A datasheet, P4SMA110A-E3/5A pinout, P4SMA110A-E3/5A application, or P4SMA110A-E3/5A equivalent, key selection criteria include unidirectional polarity, SMA (DO-214AC) package compatibility, AEC-Q101 qualification status, thermal resistance (RθJA = 120 °C/W), and clamping performance under repetitive surge conditions.
Technical Context
This device operates as a voltage-clamping protector: when reverse-biased voltage exceeds VBR, it avalanches rapidly to limit transient energy, with low incremental surge resistance ensuring minimal voltage overshoot during 10/1000 µs surges. Its glass-passivated junction enables stable breakdown characteristics and long-term reliability under repeated stress.
The P4SMA110A-E3/5A is rated for 150 °C maximum junction temperature and derates linearly above 25 °C ambient per Figure 2; its 3.3 W steady-state power dissipation (PD) and 40 A non-repetitive forward surge rating (IFSM) support use in high-energy switching environments without thermal runaway.
Key Specifications

IC Role / Device Role / Timing Role: Unidirectional clamp on +3.3 V or +5 V bias rails, triggered only during overvoltage events while remaining transparent during normal operation. Use Value: Maintains signal integrity by adding <1 pF junction capacitance at VWM, avoiding data rate degradation in 100 Mbps+ links. |
Use Scenario: Output overvoltage clamp in AC/DC adapters for smart home devices, preventing damage to downstream USB-PD or battery management ICs. IC Role / Device Role / Timing Role: Final-stage TVS connected between DC output and ground, activated only if primary regulation fails or during hot-plug insertion surges. Use Value: Provides fail-safe shutdown margin by clamping to 152 V before 100 V-rated secondary-side components exceed absolute maximum ratings. |
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), RθJA = 90 °C/W | Better thermal performance and surge handling, but larger footprint (4.6 × 3.9 mm vs. 4.3 × 2.6 mm) | Select SMBJ110A when higher surge margin or improved thermal dissipation is required and PCB space permits larger package. |
| 1.5SMC110A | Same VBR, but SMC package (DO-214AB); 1500 W PPPM, 13.3 A IPPM, RθJA = 60 °C/W | Designed for high-power industrial surge standards (IEC 61000-4-5 Level 4), not optimized for compact consumer layouts | Choose 1.5SMC110A for mains-connected equipment requiring Level 4 immunity, where footprint and cost are secondary to ruggedness. |
Compared with SMBJ110A and 1.5SMC110A, the P4SMA110A-E3/5A offers optimal balance of compact SMA footprint, 400 W surge capability, and commercial-grade RoHS compliance-making it ideal for space-constrained automotive and industrial control modules where moderate surge levels apply.

FAQ
What is the maximum clamping voltage of the P4SMA110A-E3/5A under standard test conditions?
The P4SMA110A-E3/5A has a maximum clamping voltage (VC) of 152 V when subjected to a 10/1000 µs waveform at 2.0 A peak pulse current. This value is measured per Figure 1 and Table on page 2 of Vishay document 88367, and defines the upper voltage limit imposed on protected circuits during transient events. The P4SMA110A-E3/5A maintains this clamping performance across its full operating temperature range.
Is the P4SMA110A-E3/5A AEC-Q101 qualified?
No, the P4SMA110A-E3/5A is not AEC-Q101 qualified. Its E3 suffix denotes RoHS-compliant commercial-grade construction. For AEC-Q101 qualification, Vishay specifies the HE3 or HM3 suffix variants (e.g., P4SMA110AHE3_A). The P4SMA110A-E3/5A meets all electrical and mechanical specifications of the P4SMA family but lacks the extended reliability testing required for automotive qualification.
What does the "/5A" in P4SMA110A-E3/5A indicate?
The "/5A" suffix in P4SMA110A-E3/5A specifies the packaging configuration: 13-inch diameter plastic tape and reel containing 7500 units. This contrasts with "/61", which denotes a 7-inch reel with 1800 units. The "5A" code is part of Vishay's ordering nomenclature for reel size and quantity, not a performance or revision identifier. The P4SMA110A-E3/5A shares identical electrical and thermal characteristics with other P4SMA110A-E3 variants.
Can the P4SMA110A-E3/5A be used in bidirectional applications?
No, the P4SMA110A-E3/5A is strictly unidirectional. Its part number ends in "A", indicating unidirectional polarity with cathode marked by a band. For bidirectional operation, Vishay specifies the "CA" suffix (e.g., P4SMA110CA). Using the P4SMA110A-E3/5A in reverse-biased AC or symmetrical surge scenarios would result in forward conduction and potential failure.
What is the thermal resistance junction-to-ambient (RθJA) for the P4SMA110A-E3/5A?
The typical thermal resistance junction-to-ambient (RθJA) for the P4SMA110A-E3/5A is 120 °C/W, measured on the minimum recommended pad layout per Vishay document 88367, page 3. This value assumes standard FR-4 PCB with 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. Derating must be applied above 25 °C ambient per Figure 2 in the datasheet to maintain safe junction temperature in the P4SMA110A-E3/5A.
