Product details
Overview
P4SMA110AHE3_A/I 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 110 V breakdown voltage (VBR min/max: 105–116 V), 94.0 V standoff voltage (VWM), 152 V maximum clamping voltage at 2.0 A peak pulse current (IPPM), and 400 W peak pulse power rating with 10/1000 µs waveform - suitable for automotive-grade protection of 12 V/24 V board-level circuits.
For engineers reviewing the P4SMA110AHE3_A/I datasheet, P4SMA110AHE3_A/I pinout, P4SMA110AHE3_A/I application, or P4SMA110AHE3_A/I equivalent, key selection criteria include its AEC-Q101 qualification, unidirectional polarity with cathode band marking, low incremental surge resistance, and compatibility with automated SMT placement on standard PCB copper pads per J-STD-020 MSL Level 1.
Technical Context
The P4SMA110AHE3_A/I operates as a clamping-type TVS diode that enters avalanche conduction when transient voltage exceeds its VBR threshold, limiting downstream voltage to ≤152 V at 2.0 A IPPM. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while thermal resistance RθJA = 120 °C/W enables operation up to TJ = 150 °C.
Designed for single-polarity DC line protection, it supports repetitive surge duty cycles up to 0.01 % (300 W derated above 91 V), complies with UL 497B recognition (QVGQ2), and uses matte tin-plated leads solderable per J-STD-002 and JESD 22-B102 - meeting automotive reliability requirements without external biasing or control circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V / 116 V at 1.0 mA test current - defines precise avalanche onset range for predictable clamping behavior |
| VWM | 94.0 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 152 V at 2.0 A peak pulse current - limits protected circuit voltage during worst-case 10/1000 µs surge |
| PPPM | 400 W (10/1000 µs waveform) - sustains high-energy transients common in automotive load-dump and inductive switching |
| IFSM | 40 A (8.3 ms half-sine) - withstands non-repetitive forward surge events such as hot-swap or power-up inrush |
| TJ max | +150 °C - enables use in under-hood automotive environments and industrial enclosures without derating |
| AEC-Q101 | Qualified - validated for automotive electronics per stress test requirements including HTOL, TC, UHAST |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with UL 94 V-0 flammability rating; cathode indicated by molded band on body; terminals are matte tin-plated for lead-free reflow compatibility.

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-E3/52 (Vishay) | Higher 600 W PPPM, SMB (DO-214AA) package, 125 V VC @ 3.2 A - larger footprint, higher surge margin | Better suited for high-energy industrial mains-connected equipment where PCB space allows larger package | Select when >400 W surge headroom is required and layout accommodates SMB outline |
| 1.5SMC110A (ON Semiconductor) | Same 110 V VBR, 152 V VC, but SMC (DO-214AB) package, 1.5 kW PPPM, non-AEC-Q101 rated | Targeted at commercial/industrial applications without automotive qualification requirements | Choose for cost-sensitive non-automotive designs needing identical electrical specs but no AEC validation |
Compared with P4SMA110AHE3_A/I, SMBJ110A-E3/52 offers higher surge capacity in a larger package, while 1.5SMC110A matches clamping performance without automotive qualification - making P4SMA110AHE3_A/I the optimal choice for space-constrained AEC-Q101-compliant automotive modules.

FAQ
What is the clamping voltage of the P4SMA110AHE3_A/I under a 10/1000 µs surge?
The P4SMA110AHE3_A/I has 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 measured per Figure 1 in the Vishay datasheet (Document Number: 88367) and reflects the actual voltage seen by protected circuitry during worst-case transient events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the P4SMA110AHE3_A/I qualified for automotive applications?
Yes, the P4SMA110AHE3_A/I is AEC-Q101 qualified, as confirmed by the "HE3" suffix and documentation in the Vishay P4SMA Series datasheet (Revision: 09-Jan-2024). This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing - validating its suitability for under-hood and chassis-mounted automotive electronics.
What does the "_A/I" suffix mean in P4SMA110AHE3_A/I?
The "_A/I" suffix in P4SMA110AHE3_A/I indicates packaging and revision: "A" denotes the voltage variant (110 V VBR), "I" specifies 7500-unit tape-and-reel delivery on 13-inch reels (per Vishay ordering table, Document Number: 88367, page 3). The "HE3" portion confirms RoHS-compliant, AEC-Q101-qualified construction with matte tin plating.
How does the P4SMA110AHE3_A/I compare to bidirectional TVS diodes like P4SMA110CA?
The P4SMA110AHE3_A/I is unidirectional and features a cathode band for polarity-sensitive placement, whereas P4SMA110CA is bidirectional with symmetric clamping in both directions and no polarity marking. The P4SMA110AHE3_A/I provides tighter leakage control (1.0 µA at 94 V) and is optimized for DC rail protection, while P4SMA110CA suits AC-coupled or differential signal lines where polarity reversal may occur.
What is the thermal resistance and maximum junction temperature of the P4SMA110AHE3_A/I?
The P4SMA110AHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W and a maximum junction temperature (TJ) of +150 °C. These values assume mounting on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per datasheet conditions - enabling reliable operation in ambient temperatures up to +125 °C when power dissipation remains within derated limits.
