Product details
Overview
P6SMB220CAHE3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 220 V standoff voltage (VWM), 231 V minimum breakdown voltage (VBR), and 328 V maximum clamping voltage (VC) at 1.8 A peak pulse current (IPPM), used to protect power rails and signal lines in automotive and industrial electronics against ESD and lightning-induced transients.
For engineers reviewing the P6SMB220CAHE3_A/H datasheet, P6SMB220CAHE3_A/H pinout, P6SMB220CAHE3_A/H application, or P6SMB220CAHE3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 600 W peak pulse power rating with 10/1000 μs waveform, low thermal resistance (RθJL = 20 °C/W), and RoHS-compliant matte tin-plated terminals solderable per J-STD-002.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling 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 low incremental surge resistance supports consistent clamping under repetitive transient events.
The device is rated for 600 W peak pulse power (10/1000 μs), derated above 25 °C per Fig. 2, and features a maximum junction temperature of +150 °C. It meets MSL Level 1 per J-STD-020 with peak reflow temperature up to 260 °C, and is qualified to AEC-Q101 for automotive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 185 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (Breakdown Voltage) | 209–231 V at 1 mA - Confirmed avalanche conduction threshold under controlled test conditions |
| VC (Clamping Voltage) | 328 V at IPPM = 1.8 A - Peak voltage seen across protected circuit during 10/1000 μs transient |
| PPPM (Peak Pulse Power) | 600 W - Sustained transient energy absorption capability with standard 10/1000 μs waveform |
| RθJL (Junction-to-Lead Thermal Resistance) | 20 °C/W - Enables efficient heat transfer to PCB copper pads during surge events |
| TJ max. | +150 °C - Maximum allowable junction temperature for reliable long-term operation |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: Protecting 24 V supply lines in engine control units (ECUs) and lighting modules from load dump and inductive switching transients. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed between power rail and ground to limit voltage excursions below system IC absolute maximum ratings. Use Value: Clamps to ≤328 V during 10/1000 μs surges, preventing damage to downstream DC-DC converters and microcontrollers rated for 36 V input. |
Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA current loops) and digital sensor interfaces (CAN, LIN) in factory automation equipment. IC Role / Device Role / Timing Role: Low-capacitance bidirectional suppressor placed across differential signal pairs or supply/return lines to absorb ESD and fast transients. Use Value: Sub-1.0 μA leakage at 185 V ensures minimal impact on precision current-loop accuracy; symmetrical clamping preserves signal integrity on bidirectional buses. |
| Telecom Line Card Surge Protection | Consumer Appliance Motor Drive Protection |
|
Use Scenario: Front-end protection of Ethernet PHYs and PoE injectors exposed to lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Primary-level TVS on RJ45 interface side, coordinated with GDT or polymer PTC secondary protection. Use Value: 600 W rating enables compliance with IEC 61000-4-5 Ed. 3 (4 kV line-earth, 2 kV line-line) when combined with appropriate series impedance. |
Use Scenario: Suppressing commutation spikes from brushed DC motors in washing machines, HVAC blowers, and power tools. IC Role / Device Role / Timing Role: Across-motor placement to clamp inductive kickback during MOSFET/FET switching transitions. Use Value: 328 V clamping voltage prevents MOSFET drain-source breakdown in 200–250 V motor drive stages; AEC-Q101 qualification supports extended product lifecycle in white goods. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220CA | Same SMB package, 220 V VWM, but rated for 600 W with 1.0 ms pulse width; no AEC-Q101 qualification in standard version | Commercial/industrial use only; not validated for automotive temperature cycling or humidity testing | Select when AEC-Q101 is not required and cost sensitivity outweighs automotive reliability validation |
| SMCJ220CA | Larger SMC (DO-214AB) package; same 220 V VWM and 328 V VC, but higher 1500 W PPPM rating and RθJL = 15 °C/W | Used where higher single-pulse energy handling is needed (e.g., 10/1000 μs surges >600 W) or board space allows larger footprint | Choose when system-level surge tests exceed 600 W or thermal management requires lower junction-to-lead resistance |
Compared with SMBJ220CA and SMCJ220CA, P6SMB220CAHE3_A/H uniquely combines AEC-Q101 qualification, SMB footprint, and verified 600 W performance-making it optimal for space-constrained automotive modules where reliability certification is mandatory and peak power demands remain within 600 W limits.

FAQ
What does the "CA" suffix indicate in P6SMB220CAHE3_A/H?
The "CA" suffix denotes a bidirectional configuration, meaning the P6SMB220CAHE3_A/H provides symmetrical clamping in both polarities-ideal for protecting AC-coupled circuits, differential buses, or ungrounded power rails without polarity constraints. Unlike unidirectional variants (e.g., P6SMB220A), it has no cathode band marking and exhibits identical VBR and VC characteristics in either direction.
Is P6SMB220CAHE3_A/H qualified for automotive applications?
Yes, P6SMB220CAHE3_A/H is AEC-Q101 qualified, as confirmed by the "HE3" suffix and Vishay documentation. This qualification covers temperature cycling, high-temperature reverse bias (HTRB), and ESD testing per automotive reliability standards, making it suitable for under-hood and cabin modules in passenger vehicles and commercial vehicles.
What is the maximum clamping voltage of P6SMB220CAHE3_A/H and at what current is it specified?
The maximum clamping voltage (VC) of P6SMB220CAHE3_A/H is 328 V, measured at a peak pulse current (IPPM) of 1.8 A using the standard 10/1000 μs double-exponential waveform. This value defines the worst-case voltage imposed on protected circuitry during surge events and is critical for ensuring downstream ICs remain within their absolute maximum voltage ratings.
How does the SMB (DO-214AA) package of P6SMB220CAHE3_A/H compare thermally to larger packages like SMC?
P6SMB220CAHE3_A/H has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, which is higher than the ~15 °C/W of the larger SMC (DO-214AB) package used in SMCJ220CA. This means the SMB package relies more heavily on adequate PCB copper pad area (0.2" × 0.2") for effective heat dissipation during repetitive surges, as noted in Vishay's derating curves.
Can P6SMB220CAHE3_A/H be used in place of P6SMB220A in a design?
No-P6SMB220CAHE3_A/H is bidirectional while P6SMB220A is unidirectional. Substituting them requires verifying circuit topology: P6SMB220A includes a cathode band and conducts forward current in one direction only, whereas P6SMB220CAHE3_A/H has no polarity marking and clamps equally in both directions. Using the wrong type may result in unintended conduction or inadequate protection.
