Product details
Overview
P4SMA110AHE3_A/H 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 at 1.0 mA), 94.0 V standoff voltage (VWM), 152 V maximum clamping voltage (VC) at 2.0 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - suitable for automotive-grade protection of 24 V/48 V industrial control inputs.
For engineers reviewing the P4SMA110AHE3_A/H datasheet, P4SMA110AHE3_A/H pinout, P4SMA110AHE3_A/H application, or P4SMA110AHE3_A/H equivalent, key selection criteria include its AEC-Q101 qualification, unidirectional polarity with cathode band marking, low incremental surge resistance, and compliance with UL 497B for telecom/sensor line protection.
Technical Context
This TVS diode operates as a voltage-clamping device triggered by transient overvoltage events exceeding its reverse standoff voltage (94.0 V). Its glass-passivated junction enables fast response time (<1 ns) and stable breakdown behavior under repetitive 10/1000 µs surges up to 400 W (derated to 300 W above 91 V).
The device is rated for continuous power dissipation of 3.3 W on infinite heatsink at 50 °C, with thermal resistance of 120 °C/W (junction-to-ambient) and 30 °C/W (junction-to-lead). It supports operating junction temperatures from –65 °C to +150 °C and meets J-STD-020 MSL Level 1 reflow profile (260 °C peak).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V / 116 V at 1.0 mA test current - defines precise clamping onset threshold for overvoltage detection |
| 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 - actual clamped voltage during worst-case transient, limiting downstream stress |
| PPPM | 400 W (10/1000 µs waveform) - surge energy handling capacity for short-duration transients like ESD or load dump |
| IFSM | 40 A (8.3 ms half-sine) - forward surge capability for accidental polarity reversal or inrush scenarios |
| TJ max. | +150 °C - enables reliable operation in under-hood automotive or high-temperature industrial environments |

Use Scenario: Protecting 24 V supply and sensor signal lines in BCMs from load-dump transients (ISO 7637-2 Pulse 5a) and coupled noise. IC Role / Device Role / Timing Role: Unidirectional TVS clamping element placed between input rail and ground, activated within <1 ns upon overvoltage event. Use Value: Limits voltage seen by downstream LDOs and microcontrollers to ≤152 V, preventing latch-up or permanent damage during 120 V/500 ms load dump. |
Use Scenario: Safeguarding 4–20 mA current-loop analog inputs on programmable logic controllers against field-wiring induced surges. IC Role / Device Role / Timing Role: Standoff-mode protector across input terminals, conducting only when transient exceeds 94.0 V. Use Value: Maintains <1 µA leakage at 24 V nominal, preserving loop accuracy while clamping 1 kV/500 A transients to safe levels for op-amp front-end stages. |
| Telecom Line Interface Protection | Automotive Camera Power Rail Protection |
|
Use Scenario: Shielding RS-485/RS-232 data lines and auxiliary power feeds in base station equipment from lightning-induced surges. IC Role / Device Role / Timing Role: Primary clamping device on DC bias rails feeding line drivers, coordinated with secondary GDT or MOV stages. Use Value: UL 497B recognition ensures compliance with telecom safety standards; 152 V clamping prevents damage to isolated DC/DC converters and level shifters. |
Use Scenario: Securing 12 V power input to rear-view or surround-view camera modules exposed to automotive electrical noise and jump-start conditions. IC Role / Device Role / Timing Role: First-line transient suppressor on main power entry, placed upstream of buck converter and image sensor IC. Use Value: AEC-Q101 qualification guarantees performance over full automotive temperature range (–40 °C to +125 °C ambient), with no derating required up to 150 °C junction. |
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) | Same VBR/VWM/VC, but SMB (DO-214AA) package - 2.5 mm wider, higher thermal mass, 600 W PPPM | Higher power handling suits 48 V battery systems; larger footprint may conflict with dense layouts | Select when board space allows and >400 W surge margin is required; not drop-in due to different pad layout |
| 1.5SMC110A (ON Semiconductor) | Identical electrical specs (VBR: 105–116 V, VC: 152 V), same SMA package, but not AEC-Q101 qualified | Lacks automotive qualification; suitable for industrial/commercial use only | Choose for cost-sensitive non-automotive designs where AEC-Q101 is not mandated |
Compared with P4SMA110AHE3_A/H, SMBJ110A-E3/52 offers higher surge rating but requires PCB redesign, while 1.5SMC110A matches form/fit/function for non-automotive use but omits AEC-Q101 validation - making P4SMA110AHE3_A/H the sole choice for production automotive applications requiring both qualification and SMA footprint.

FAQ
What is the breakdown voltage tolerance for P4SMA110AHE3_A/H?
The P4SMA110AHE3_A/H has a breakdown voltage (VBR) range of 105 V to 116 V at 1.0 mA test current, corresponding to ±5 % tolerance around the nominal 110 V rating. This tight tolerance ensures predictable clamping behavior across production lots and temperature ranges, critical for protecting sensitive 24 V system components without premature triggering.
Is P4SMA110AHE3_A/H suitable for bidirectional transient protection?
No, P4SMA110AHE3_A/H is a unidirectional TVS diode - it conducts only in reverse bias above VWM and blocks forward current beyond its 3.5 V forward voltage at 25 A. For bidirectional protection, Vishay offers the P4SMA110CA variant; using P4SMA110AHE3_A/H in AC-coupled or symmetrical signal paths would require external circuitry to prevent forward conduction damage.
Does P4SMA110AHE3_A/H meet automotive qualification standards?
Yes, P4SMA110AHE3_A/H is AEC-Q101 qualified - verified per stress tests including high-temperature operating life (HTOL), temperature cycling (TCT), and human-body-model ESD (HBM ≥ 8 kV). The "HE3" suffix explicitly denotes RoHS-compliant and AEC-Q101 qualified construction, making it approved for use in automotive ECUs, sensors, and infotainment power supplies.
What is the maximum clamping voltage of P4SMA110AHE3_A/H under surge conditions?
The maximum clamping voltage (VC) of P4SMA110AHE3_A/H is 152 V at 2.0 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value represents the highest voltage imposed on the protected circuit during a standardized transient event, directly determining whether downstream ICs remain within their absolute maximum ratings.
How does the thermal resistance of P4SMA110AHE3_A/H affect PCB layout?
P4SMA110AHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W, meaning each watt of dissipated power raises junction temperature by 120 °C above ambient. To maintain safe operation below 150 °C junction limit, PCB layout must provide adequate copper area (minimum 0.2" × 0.2" pads per terminal per Vishay recommendation) and avoid thermal bottlenecks near the device.
