Product details
Overview
P4SMA180AHE3/5A from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, rated for 180 V standoff voltage (VWM), 199.5 V minimum breakdown voltage (VBR), and 246 V maximum clamping voltage (VC) at 1.2 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 P4SMA180AHE3/5A datasheet, P4SMA180AHE3/5A pinout, P4SMA180AHE3/5A application, or P4SMA180AHE3/5A equivalent, key selection considerations include its AEC-Q101 qualification, 400 W peak pulse power rating (10/1000 µs), 154 V reverse leakage limit at VWM, 120 °C/W junction-to-ambient thermal resistance, and RoHS-compliant matte tin-plated leads suitable for J-STD-002 soldering.
Technical Context
This unidirectional TVS diode operates by avalanche breakdown above its specified VBR (171–189 V), delivering precise clamping with low incremental surge resistance and fast response time (<1 ns). Its glass-passivated junction ensures stable performance under repetitive surge conditions.
Rated for 400 W peak pulse power (10/1000 µs waveform) up to TA = 25 °C - derated linearly above 25 °C per Fig. 2 - it supports 40 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine) and operates across -65 °C to +150 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 154 V - maximum continuous reverse operating voltage before conduction begins; defines safe operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 171–189 V at IT = 1.0 mA - guaranteed avalanche initiation range; ensures predictable turn-on during overvoltage events |
| VC (Clamping Voltage) | 246 V at IPPM = 1.2 A - peak voltage seen by protected circuit during 10/1000 µs transient; determines stress on downstream components |
| PPPM (Peak Pulse Power) | 400 W (10/1000 µs) - energy-handling capability under standardized surge; enables protection against IEC 61000-4-5 Level 3/4 surges |
| ID (Reverse Leakage) | 1.0 µA max at VWM = 154 V - minimal standby power loss and signal integrity impact in high-impedance circuits |
| TJ max. | +150 °C - allows operation in under-hood automotive environments and thermally constrained industrial enclosures |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads; polarity indicated by cathode band on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to lower-potential side of protected line | Provides path for surge current to ground when cathode is held at higher potential; must be routed with low-inductance trace |
| Cathode | Current exit terminal in forward bias; marked with band; connected to protected line or supply rail | Serves as clamping node - voltage at this terminal is clamped to ≤246 V during transients; requires solid grounding to shunt energy |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure |
| MSL Level 1 (260 °C peak reflow) | Compatible with standard lead-free SMT reflow profiles without preconditioning or special handling |
| 400 W peak pulse power (10/1000 µs) | Supports robust protection against lightning-induced surges and inductive kickback in 24/48 V systems |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive powertrain, body control, and ADAS subsystems requiring zero-defect reliability |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (e.g., ISO 7637-2 pulse 1/2a/5a) |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 24 V battery-fed ECUs from load dump and alternator transients per ISO 16750-2. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and input filter capacitor to clamp spikes up to ±100 V. Use Value: Limits rail voltage to ≤246 V during 400 W surges, preventing damage to LDOs, CAN transceivers, and microcontrollers. |
Use Scenario: Safeguarding analog sensor outputs (e.g., pressure, temperature) in factory automation PLC modules. IC Role / Device Role / Timing Role: TVS mounted at connector interface to absorb ESD (IEC 61000-4-2 ±8 kV contact) and cable discharge events. Use Value: Clamps transients within <1 ns while adding only 1.0 µA leakage at 154 V, preserving signal accuracy and offset stability. |
| Telecom DC Power Input Protection | Motor Drive Control Signal Protection |
Use Scenario: Shielding 48 V PoE-powered equipment inputs from induced surges on long Ethernet runs. IC Role / Device Role / Timing Role: Primary clamping device upstream of DC-DC converter, sized to handle IEC 61000-4-5 combination wave (10/700 µs). Use Value: Withstands 400 W pulses without degradation, maintaining clamping performance over >10⁵ surge events per JEDEC JESD22-A114. |
Use Scenario: Protecting isolated gate driver enable signals in BLDC motor inverters exposed to cross-conduction noise. IC Role / Device Role / Timing Role: Low-capacitance TVS on logic-level control lines (e.g., EN, FAULT) to suppress fast dv/dt coupling from power stage switching. Use Value: Delivers sub-250 V clamping with negligible capacitance impact, avoiding timing skew in critical PWM paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ180A-E3/52 (Vishay) | Same VWM/VBR/VC specs but SMB (DO-214AA) package; 10% larger footprint; RθJA = 100 °C/W vs. 120 °C/W | Better thermal dissipation in high-power layouts; less suitable for ultra-dense PCBs where SMA's smaller size is critical | Select SMBJ180A-E3/52 when board space permits and thermal margin is prioritized over miniaturization |
| 1.5KE180A (ON Semiconductor) | Through-hole DO-201 package; 1.5 kW peak power (10/1000 µs); higher VC = 259 V at 6.5 A IPPM; no AEC-Q101 qualification | Designed for legacy through-hole designs and higher-energy surges; unsuitable for automotive AEC-compliant systems | Choose 1.5KE180A only for cost-sensitive industrial mains-input protection where AEC-Q101 is not required |
Compared with SMBJ180A-E3/52, P4SMA180AHE3/5A offers superior board-area efficiency and AEC-Q101 compliance but trades off ~17% thermal resistance; versus 1.5KE180A, it provides SMT manufacturability and automotive qualification at the expense of peak power headroom.

FAQ
What is the clamping voltage of the P4SMA180AHE3/5A under a 10/1000 µs surge?
The P4SMA180AHE3/5A has a maximum clamping voltage (VC) of 246 V at 1.2 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured per Figure 1 in the Vishay datasheet 88367 and defines the upper voltage limit imposed on protected circuitry during transient events.
Is the P4SMA180AHE3/5A qualified for automotive applications?
Yes, the P4SMA180AHE3/5A carries the HE3 suffix, indicating full AEC-Q101 qualification per Vishay's documentation. It has undergone stress testing for temperature cycling, high-temperature reverse bias, and ESD per AEC requirements, making it suitable for automotive powertrain, body electronics, and ADAS modules.
What is the standoff voltage rating of the P4SMA180AHE3/5A?
The P4SMA180AHE3/5A has a maximum working peak reverse voltage (VWM) of 154 V, meaning it can continuously block up to 154 V in reverse bias without significant leakage. This rating ensures reliable operation in 120 V AC-derived DC rails and 24/48 V automotive systems with margin.
Does the P4SMA180AHE3/5A have a bidirectional variant?
No - the P4SMA180AHE3/5A is strictly unidirectional, as indicated by the "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., P4SMA180CA), which provide symmetrical clamping in both polarities and lack polarity markings.
What package type does the P4SMA180AHE3/5A use?
The P4SMA180AHE3/5A uses the SMA (DO-214AC) surface-mount package: a low-profile, rectangular plastic case measuring 4.93 mm × 3.99 mm × 2.29 mm, with matte tin-plated leads compliant with J-STD-002 solderability standards and MSL Level 1 reflow compatibility.
