Product details
Overview
P4SMA180AHE3/61 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P4SMA series, designed for clamping voltage transients on power and signal lines. It features a 180 V standoff voltage (VWM), 246 V maximum clamping voltage (VC) at 1.2 A peak pulse current (IPPM), and 400 W peak pulse power capability with a 10/1000 µs waveform - suitable for protecting MOSFETs, ICs, and sensor signal lines in industrial and automotive electronics.
For engineers reviewing the P4SMA180AHE3/61 datasheet, P4SMA180AHE3/61 pinout, P4SMA180AHE3/61 application, or P4SMA180AHE3/61 equivalent, this device delivers AEC-Q101 qualification, SMA (DO-214AC) package compatibility, low incremental surge resistance, and fast response time for robust ESD and surge protection in space-constrained PCB layouts.
Technical Context
The P4SMA180AHE3/61 operates as a unidirectional avalanche diode with glass-passivated junction, enabling precise breakdown behavior and stable clamping under repetitive transient stress. Its thermal resistance (RθJA = 120 °C/W) and junction temperature range (–65 to +150 °C) support reliable operation in ambient temperatures up to 125 °C when mounted per recommended 5.0 mm × 5.0 mm copper pads.
It complies with J-STD-020 MSL Level 1 and meets UL 94 V-0 flammability requirements. The matte tin-plated leads ensure solderability per J-STD-002 and JESD 22-B102, while the HE3 suffix confirms RoHS compliance and AEC-Q101 qualification for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 154 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC working margin. |
| VBR (Breakdown Voltage) | 171–189 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 246 V at IPPM = 1.2 A - Peak voltage seen by protected circuit during 10/1000 µs surge; critical for downstream component survivability. |
| PPPM (Peak Pulse Power) | 400 W - Sustained energy absorption capability under standardized 10/1000 µs waveform; derates above 25 °C per Fig. 2. |
| ID (Reverse Leakage) | 1.0 µA max at VWM - Ultra-low leakage preserves system efficiency and prevents false triggering in high-impedance circuits. |
| TJ max | +150 °C - Enables use in under-hood automotive environments and thermally demanding industrial enclosures. |
| Package | SMA (DO-214AC) - Surface-mount footprint (5.28 mm × 4.50 mm) compatible with automated placement and reflow processes. |
Pinout & Package
Package: SMA (DO-214AC), molded plastic case with matte tin-plated leads; cathode indicated by band marking on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to ground or low-side reference in unidirectional TVS configuration. | Provides return path during clamping; must be routed to lowest-impedance ground plane for effective transient shunting. |
| Cathode | Current exit terminal in forward bias; connected to protected line (e.g., power rail or signal trace). | Acts as the "input" side of the clamp; polarity-sensitive - reversal disables protection function. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS sensor interfaces requiring long-term reliability under thermal cycling and vibration. |
| 400 W peak pulse power (10/1000 µs) | Handles IEC 61000-4-5 Level 4 surges (4 kV line-to-earth) without degradation when properly heatsinked. |
| Glass passivated junction | Ensures stable breakdown voltage over lifetime and immunity to humidity-induced parameter drift in harsh environments. |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow profiles without preconditioning; eliminates moisture-related popcorning risk. |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage exposure to protected ICs - critical for 3.3 V or 5 V logic interfacing with higher-voltage domains. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ180A | Same VWM (154 V) and VC (246 V), but SMB package (DO-214AA); 6.2 mm × 3.5 mm footprint vs. SMA's 5.3 mm × 4.5 mm. | Higher RθJA (150 °C/W) limits power handling in compact layouts; better suited for lower-density boards with larger thermal pads. | Select SMBJ180A only if existing layout uses SMB footprint or requires slightly higher surge current rating (1.3 A vs. 1.2 A). |
| SMCJ180A | Same electrical specs but SMC package (DO-214AB); 7.1 mm × 6.2 mm body with 500 W PPPM rating (vs. 400 W). | Requires 3× more board area; intended for primary-level surge protection where PCB space permits and higher energy absorption is needed. | Choose SMCJ180A when protecting upstream power inputs exposed to direct lightning coupling or high-energy switching events. |
Compared with SMBJ180A and SMCJ180A, the P4SMA180AHE3/61 offers optimal balance of automotive qualification, compact SMA footprint, and verified 400 W surge capacity - making it ideal for secondary-side protection where board area and AEC-Q101 compliance are jointly constrained.

FAQ
What is the clamping voltage of P4SMA180AHE3/61 at its rated peak pulse current?
The P4SMA180AHE3/61 has a maximum clamping voltage (VC) of 246 V when subjected to its specified peak pulse current (IPPM) of 1.2 A under a 10/1000 µs waveform. This value is measured per Figure 1 in the Vishay datasheet 88367 and represents the upper voltage limit imposed on the protected circuit during transient events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is P4SMA180AHE3/61 suitable for automotive applications?
Yes, P4SMA180AHE3/61 is AEC-Q101 qualified, as confirmed by the HE3 suffix and documentation in Vishay's P4SMA series datasheet. It undergoes stress testing for temperature cycling, humidity, mechanical shock, and surge robustness required for automotive powertrain, chassis, and body electronics - making it appropriate for use in engine control units, lighting modules, and ADAS sensor interfaces.
What does the "HE3" suffix mean in P4SMA180AHE3/61?
The "HE3" suffix in P4SMA180AHE3/61 indicates RoHS-compliant construction with AEC-Q101 qualification and matte tin-plated leads meeting J-STD-002 solderability standards. It distinguishes this variant from commercial-grade E3 or halogen-free HM3 versions, confirming suitability for automotive production and high-reliability industrial use.
How does the thermal performance of P4SMA180AHE3/61 affect PCB layout?
P4SMA180AHE3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads. To maintain TJ ≤ 150 °C under full 400 W surge conditions, designers must provide adequate copper area and avoid thermal bottlenecks - undersized traces or insufficient ground planes will cause premature thermal shutdown or parametric shift in P4SMA180AHE3/61 clamping behavior.
Can P4SMA180AHE3/61 replace a bidirectional TVS in a circuit?
No, P4SMA180AHE3/61 is strictly unidirectional and must not be substituted for a bidirectional device like P4SMA180CA without circuit redesign. Its cathode-band marking and asymmetric IV curve only protect against positive transients on the cathode side; negative excursions will forward-bias the device and cause failure. Always verify polarity alignment and transient directionality before selecting P4SMA180AHE3/61.
