Product details
Overview
P4SMA220A-E3/61 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, rated for 220 V standoff voltage (VWM), 231 V minimum breakdown voltage (VBR), and 328 A peak pulse current (IPPM) under 10/1000 μs waveform. It delivers 400 W peak pulse power capability and clamps transients to 328 V at rated current, protecting MOSFETs and ICs in industrial power supplies and telecom interfaces.
For engineers reviewing the P4SMA220A-E3/61 datasheet, P4SMA220A-E3/61 pinout, P4SMA220A-E3/61 application, or P4SMA220A-E3/61 equivalent, key selection criteria include unidirectional polarity, 185 V maximum reverse leakage at VWM, 0.91 A maximum clamping current derating above 25 °C, and AEC-Q101 qualification eligibility via HE3 suffix variants.
Technical Context
This TVS diode operates as a clamping device in parallel with sensitive circuit nodes, activating when transient voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable avalanche behavior and low incremental surge resistance, enabling sub-nanosecond response to ESD and inductive switching spikes.
The device is rated for 150 °C maximum junction temperature and exhibits 0.108 %/°C temperature coefficient of VBR. Thermal resistance is 120 °C/W junction-to-ambient (RθJA) on standard 0.2" × 0.2" copper pads, supporting reliable operation in compact, high-density PCB layouts without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 185 V - Maximum continuous reverse voltage before conduction begins; defines operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 209–231 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 328 V at IPPM - Peak voltage seen by protected circuit during 400 W transient; determines stress on downstream components. |
| IPPM (Peak Pulse Current) | 328 A - Maximum surge current survivable under 10/1000 μs waveform; validates robustness against IEC 61000-4-5 surges. |
| PPPM (Peak Pulse Power) | 400 W - Energy-handling capacity per transient; supports repeated protection in industrial control systems. |
| ID (Reverse Leakage) | 1.0 μA at VWM - Minimal standby power loss and signal integrity impact in high-impedance sensing paths. |
| TJ max. | 150 °C - Enables use in under-hood automotive modules and enclosed industrial enclosures without thermal derating penalties. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Cathode indicated by band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to ground or low-side reference in unidirectional configuration | Provides return path during clamping; must be routed with low-inductance trace to minimize overshoot. |
| Cathode | Current exit terminal in forward bias; connected to protected line (e.g., power rail or signal line) | Band-marked end; determines polarity orientation-critical for correct placement in DC-biased circuits. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-earth) in single-stage protection designs. |
| Glass passivated chip junction | Ensures stable, repeatable avalanche characteristics across temperature and lifetime-no parameter drift after 10⁵ surges. |
| MSL Level 1 (260 °C peak reflow) | Enables compatibility with standard lead-free SMT assembly processes without moisture sensitivity concerns. |
| AEC-Q101 qualification option (HE3 suffix) | Validates reliability for automotive powertrain and body electronics where extended temperature cycling and vibration endurance are required. |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (<1 ns rise time), improving protection margin for 3.3 V/5 V logic. |
Applications
| Industrial Power Supply Protection | Telecom Line Interface Protection |
|---|---|
|
Use Scenario: Protecting DC input rails of programmable logic controllers (PLCs) against inductive kickback from solenoid drivers and relay coils. IC Role / Device Role / Timing Role: Unidirectional shunt clamping device placed between +24 V rail and chassis ground. Use Value: Limits transient excursions to ≤328 V, preventing latch-up or gate oxide damage in upstream DC/DC controllers and microcontrollers. |

IC Role / Device Role / Timing Role: Primary-level TVS on differential bus lines (A/B), coordinated with common-mode chokes. Use Value: Clamps common-mode surges up to 400 W without degrading signal integrity at 10 Mbps due to low junction capacitance (<50 pF). |
| Automotive Body Control Module | Consumer Appliance Motor Drive |
|
Use Scenario: Protecting LIN bus transceivers and window lift motor drivers in door modules subjected to load dump and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS on 12 V supply line upstream of LDO regulators. Use Value: Withstands 12 V system load dump pulses (ISO 7637-2 Pulse 5a) while maintaining <1 μA leakage at nominal voltage. |
Use Scenario: Shielding BLDC motor gate drivers in smart washing machines from commutation spikes generated by inverter switching. IC Role / Device Role / Timing Role: Rail-to-rail clamping on half-bridge high-side and low-side supply nodes. Use Value: Fast response (<1 ns) and low Rsurge reduce voltage overshoot on gate drivers, eliminating false triggering and shoot-through risk. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220A | Same VWM/VBR/VC ratings but in larger SMB (DO-214AA) package; 600 W PPPM rating | Better thermal dissipation in high-duty-cycle surge environments; requires 30% more board area | Select when higher surge repetition rate (>0.01%) or elevated ambient temperature (>85 °C) demands lower RθJA |
| 1.5SMC220A | Same electrical specs but in SMC (DO-214AB) package; 1500 W PPPM rating; higher VF at IF = 25 A | Used in primary AC-input protection stages; not optimized for space-constrained secondary-side placement | Choose for front-end surge suppression where PCB real estate allows and higher energy absorption is mandatory |
Compared with P4SMA220A-E3/61, SMBJ220A offers superior thermal performance in sustained surge scenarios, while 1.5SMC220A provides higher single-pulse energy handling but sacrifices layout density-making P4SMA220A-E3/61 optimal for cost-sensitive, space-constrained secondary-side protection.

FAQ
What is the maximum clamping voltage of the P4SMA220A-E3/61 under rated surge conditions?
The P4SMA220A-E3/61 clamps to a maximum of 328 V when subjected to its rated 328 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured at 25 °C and represents the upper limit of voltage imposed on protected circuitry during transient events, directly defining the safe operating margin for downstream ICs and MOSFETs.
Is the P4SMA220A-E3/61 suitable for automotive applications?
The P4SMA220A-E3/61 itself is commercial-grade; however, the P4SMA220AHE3_A variant (same electrical specs, HE3 suffix) is AEC-Q101 qualified and approved for automotive body electronics, including LIN bus protection and motor driver circuits. Always verify the full ordering code-including suffix-for automotive qualification.
What is the thermal resistance of the P4SMA220A-E3/61, and how does it affect PCB layout?
The P4SMA220A-E3/61 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 per terminal. This value assumes minimal copper area-designers should allocate adequate thermal pad area and consider internal plane connections to maintain TJ ≤ 150 °C under repetitive surge conditions.
Does the P4SMA220A-E3/61 have bidirectional capability?
No-the P4SMA220A-E3/61 is strictly unidirectional. Bidirectional variants carry a "C" suffix (e.g., P4SMA220CA). The "A" suffix denotes unidirectional construction with cathode band marking; using this part in AC-coupled or bipolar signal paths will result in forward conduction and potential failure.
What packaging format is used for the P4SMA220A-E3/61, and what does the "/61" suffix indicate?
The P4SMA220A-E3/61 ships in 7-inch diameter plastic tape-and-reel packaging with 1800 units per reel. The "/61" denotes the reel size and packaging configuration per Vishay's ordering convention; "E3" confirms RoHS-compliant, commercial-grade matte tin plating and J-STD-020 MSL Level 1 compliance.
