Product details
Overview
P4SMA220CAHE3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, rated for 220 V breakdown voltage (VBR = 209–231 V at IT = 1.0 mA), 185 V stand-off voltage (VWM), and 328 A peak pulse current (IPPM) under 10/1000 µs waveform. It delivers 400 W peak pulse power capability and is AEC-Q101 qualified for automotive-grade reliability in voltage transient protection circuits.
For engineers reviewing the P4SMA220CAHE3_A/H datasheet, P4SMA220CAHE3_A/H pinout, P4SMA220CAHE3_A/H application, or P4SMA220CAHE3_A/H equivalent, this device serves as a robust clamping solution for bidirectional signal line protection in automotive sensor interfaces, industrial control I/O, and telecom power rails where fast response (<1 ns), low clamping voltage (VC = 328 V), and MSL Level 1 reflow compatibility are critical.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical electrical characteristics in forward and reverse directions - enabling single-device protection of AC-coupled or differential signal paths without polarity concerns. Its glass-passivated junction ensures stable breakdown behavior and low leakage (≤1.0 µA at VWM), while the 0.068 %/°C temperature coefficient of VBR maintains predictable clamping over -65 °C to +150 °C operating range.
The device uses a planar silicon avalanche structure optimized for low incremental surge resistance (rd), resulting in tight clamping performance (VC/VBR ratio ≈ 1.57) and minimal voltage overshoot during ESD or lightning-induced transients. Mounted on standard 5.0 mm × 5.0 mm copper pads, it achieves 400 W peak pulse power rating per JEDEC JESD22-A115A test conditions, derating linearly above TA = 25 °C per Fig. 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 209 V / 231 V at IT = 1.0 mA - defines reliable avalanche initiation threshold for bidirectional clamping |
| VWM | 185 V - maximum continuous working voltage before leakage exceeds 1.0 µA; sets safe operating margin below VBR |
| VC @ IPPM | 328 V at 328 A (10/1000 µs) - clamped voltage seen by protected circuit during worst-case surge |
| PPPM | 400 W - peak transient energy absorption capacity without failure under standardized surge waveform |
| IPPM | 328 A - maximum non-repetitive surge current the device sustains without degradation |
| TJ max. | +150 °C - enables operation in under-hood automotive environments and high-ambient industrial settings |
| MSL Level | Level 1 (J-STD-020) - supports lead-free reflow up to 260 °C peak without moisture-induced damage |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220CA | Same VBR range (209–231 V), but SMB package (DO-214AA); 600 W PPPM, higher thermal mass, larger footprint (0.236" × 0.157") | Better suited for higher-energy surges where board space allows; less suitable for ultra-dense automotive modules | Select SMBJ220CA if surge energy exceeds 400 W capability and PCB layout permits larger pad area. |
| 1.5KE220CA | Through-hole DO-201 package; same VBR and VC, but 1500 W PPPM; significantly higher IPPM (68.9 A), lower mounting density, no AEC-Q101 qualification | Used in legacy industrial power supplies and AC mains protection where manual assembly or high single-pulse energy is required | Choose 1.5KE220CA only for through-hole designs or non-automotive applications requiring >400 W surge handling. |
Compared with SMBJ220CA and 1.5KE220CA, P4SMA220CAHE3_A/H offers optimal balance of AEC-Q101 qualification, compact SMA footprint, and 400 W surge rating - making it the preferred choice for new automotive and space-constrained industrial designs requiring validated reliability and SMT scalability.

FAQ
What is the clamping voltage of P4SMA220CAHE3_A/H at its rated peak pulse current?
The P4SMA220CAHE3_A/H has a maximum clamping voltage (VC) of 328 V when subjected to its rated peak pulse current of 328 A under the standard 10/1000 µs waveform. This value is measured per JEDEC JESD22-A115A and reflects the upper limit of voltage imposed on the protected circuit during worst-case transient events. The actual clamping voltage of P4SMA220CAHE3_A/H may be lower depending on surge rise time and PCB layout parasitics.
Is P4SMA220CAHE3_A/H suitable for automotive applications?
Yes, P4SMA220CAHE3_A/H is AEC-Q101 qualified and explicitly designated for automotive use with the "HE3" suffix indicating RoHS-compliant and AEC-Q101-qualified construction. It meets stringent requirements for temperature cycling, humidity resistance, and mechanical shock - making P4SMA220CAHE3_A/H appropriate for engine control units, body electronics, and ADAS sensor modules where reliability under harsh conditions is mandatory.
What does the "CA" suffix mean in P4SMA220CAHE3_A/H?
The "CA" suffix in P4SMA220CAHE3_A/H denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities, with identical breakdown and clamping characteristics regardless of voltage polarity applied. Unlike unidirectional variants (e.g., P4SMA220A), P4SMA220CAHE3_A/H requires no orientation during placement and is ideal for protecting AC signals, differential buses, or floating grounds.
What is the maximum operating temperature for P4SMA220CAHE3_A/H?
The P4SMA220CAHE3_A/H has a maximum junction temperature (TJ) of +150 °C and an operating junction/storage temperature range of -65 °C to +150 °C. This wide thermal envelope supports deployment in under-hood automotive locations and industrial enclosures with elevated ambient temperatures. Derating of peak pulse power begins above TA = 25 °C per Figure 2 in the datasheet, ensuring safe operation across the full P4SMA220CAHE3_A/H temperature range.
How does the SMA package of P4SMA220CAHE3_A/H compare to SMB or SMC packages in terms of surge handling?
The SMA (DO-214AC) package of P4SMA220CAHE3_A/H delivers 400 W peak pulse power with a compact 0.208" × 0.157" footprint, whereas SMB (DO-214AA) offers 600 W and SMC (DO-214AB) supports up to 1500 W - reflecting trade-offs between size, thermal mass, and surge capacity. P4SMA220CAHE3_A/H is optimized for space-constrained designs where 400 W suffices; for higher-energy threats, larger packages like SMBJ220CA or SMCJ220CA are recommended - but P4SMA220CAHE3_A/H remains optimal for cost-sensitive, high-volume automotive modules.
