Product details
Overview
P4SMA160AHE3/5A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, rated for 160 V standoff voltage (VWM), 171 V minimum breakdown voltage (VBR), and 219 V maximum clamping voltage (VC) at 1.4 A peak pulse current (IPPM), designed to protect power rails and signal lines in automotive and industrial electronics against ESD and inductive switching transients.
For engineers reviewing the P4SMA160AHE3/5A datasheet, P4SMA160AHE3/5A pinout, P4SMA160AHE3/5A application, or P4SMA160AHE3/5A equivalent, key selection criteria include its AEC-Q101 qualification, 400 W peak pulse power rating (10/1000 µs), low thermal resistance (RθJL = 30 °C/W), and RoHS-compliant matte tin-plated leads suitable for automated SMT assembly.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, leveraging glass-passivated junction technology for stable avalanche behavior and fast response (<1 ns). Its 160 V VWM enables use on 130–150 V DC bus lines where transient suppression must avoid false triggering during normal operation.
The device delivers 219 V clamping at 1.4 A IPPM under 10/1000 µs waveform, with 0.108 %/°C temperature coefficient of VBR ensuring predictable voltage drift across -65 °C to +150 °C operating range. It meets MSL Level 1 per J-STD-020 and supports reflow up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin for 130 V nominal systems. |
| VBR (Breakdown Voltage) | 152–168 V at 1 mA - Confirmed avalanche onset range; ensures reliable turn-on without premature conduction. |
| VC (Clamping Voltage) | 219 V at 1.4 A IPPM - Peak voltage seen by protected circuit during 10/1000 µs surge; determines downstream component voltage stress. |
| PPPM (Peak Pulse Power) | 400 W - Sustained energy absorption capability under standard lightning/surge waveform; derates to 300 W above 91 V. |
| ID (Reverse Leakage) | 1.0 µA max at VWM - Negligible standby current; avoids loading sensitive high-impedance nodes. |
| TJ max | +150 °C - Enables deployment in under-hood automotive environments and enclosed industrial enclosures. |
| RθJL | 30 °C/W - Low junction-to-lead thermal resistance supports efficient heat transfer to PCB copper pads without heatsink. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A-E3/52 | Same VWM (136 V), higher VC (230 V), SMB package (DO-214AA), 600 W PPPM rating | Larger footprint; better suited for higher-energy surges but requires more board area | Select when surge energy exceeds 400 W or PCB layout allows larger SMB package |
| 1.5KE160A | Through-hole DO-201AE package, same VWM/VC specs, 1500 W PPPM, higher IFSM (200 A) | Not SMT-compatible; used in legacy or high-reliability through-hole designs with manual assembly | Choose only for through-hole production or where mechanical robustness outweighs SMT efficiency |
Compared with P4SMA160AHE3/5A, SMBJ160A-E3/52 offers higher surge capacity in a slightly larger SMT package, while 1.5KE160A provides legacy through-hole compatibility and greater single-pulse robustness-but neither matches the AEC-Q101 qualification and MSL Level 1 reflow readiness of P4SMA160AHE3/5A.

FAQ
What is the clamping voltage of P4SMA160AHE3/5A at its rated peak pulse current?
The P4SMA160AHE3/5A has a maximum clamping voltage (VC) of 219 V at 1.4 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per Figure 1 in Vishay document 88367 and defines the upper voltage limit imposed on protected circuitry during surge events. The P4SMA160AHE3/5A maintains this clamping performance across its full operating temperature range (-65 °C to +150 °C).
Is P4SMA160AHE3/5A qualified for automotive applications?
Yes, P4SMA160AHE3/5A is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation in revision 09-Jan-2024 of datasheet 88367. This qualification covers stress tests including temperature cycling, high-temperature reverse bias, and ESD, making P4SMA160AHE3/5A suitable for under-hood and cabin electronics in passenger vehicles and commercial fleets.
What is the thermal resistance from junction to lead (RθJL) for P4SMA160AHE3/5A?
The P4SMA160AHE3/5A has a typical junction-to-lead thermal resistance (RθJL) of 30 °C/W, per Vishay's Thermal Characteristics table in document 88367. This low value enables effective heat dissipation into PCB copper pads without external heatsinking-especially critical during repetitive surge events in automotive and industrial environments where ambient temperatures exceed 85 °C.
Does P4SMA160AHE3/5A have a bidirectional variant?
No, P4SMA160AHE3/5A is strictly unidirectional, indicated by the "A" suffix and cathode-band marking. Bidirectional variants use the "CA" suffix (e.g., P4SMA160CA). The P4SMA160AHE3/5A is intended for rail-to-ground clamping; using it in bidirectional configurations would result in forward conduction during negative transients and potential failure.
What packaging format does P4SMA160AHE3/5A ship in?
P4SMA160AHE3/5A ships in 13-inch diameter plastic tape and reel, with a base quantity of 7500 units per reel, denoted by the "/5A" suffix in the ordering code.
