Product details
Overview
P6SMB220CAHE3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the 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), designed to protect sensitive signal lines and power rails in automotive and industrial electronics against ESD and lightning-induced transients.
For engineers reviewing the P6SMB220CAHE3/5B datasheet, P6SMB220CAHE3/5B pinout, P6SMB220CAHE3/5B application, or P6SMB220CAHE3/5B equivalent, this device delivers AEC-Q101 qualification, 600 W peak pulse power (10/1000 μs), low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for high-reliability automotive PCB designs requiring robust transient suppression without layout redesign.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical electrical characteristics in forward and reverse directions, enabling simplified protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction ensures stable leakage performance and fast response time (<1 ns) to transient events.
The device uses a planar silicon avalanche structure optimized for low clamping ratio (VC/VBR ≈ 1.42) and minimal thermal resistance (RθJL = 20 °C/W), supporting repetitive surge handling under derated conditions up to TJ = 150 °C. It meets J-STD-020 MSL Level 1 and is qualified per AEC-Q101 for automotive under-hood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 220 V - Maximum continuous reverse operating voltage before significant conduction begins; defines safe operating margin for 24 V–48 V DC systems with transient headroom. |
| VBR (Breakdown Voltage) | 209–231 V at IT = 1 mA - Voltage at which avalanche conduction initiates; tight 10% tolerance enables predictable turn-on behavior in overvoltage protection circuits. |
| VC (Clamping Voltage) | 328 V at IPPM = 1.8 A - Maximum voltage seen by protected circuit during 10/1000 μs surge; determines stress on downstream ICs and MOSFETs. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability under standardized 10/1000 μs waveform; supports IEC 61000-4-5 Level 4 surge immunity testing. |
| ID (Reverse Leakage) | 1.0 μA max at VWM - Ultra-low leakage preserves signal integrity and battery life in always-on sensor interfaces and low-power microcontrollers. |
| TJ max | 150 °C - Maximum junction temperature rating; enables operation in under-hood automotive environments and industrial enclosures without forced cooling. |
| Package | SMB (DO-214AA) - Industry-standard surface-mount outline with 5.59 mm × 4.06 mm footprint and 2.20 mm height; compatible with automated pick-and-place and reflow soldering. |
Pinout & Package
SMB (DO-214AA) package: two-terminal, symmetrical bidirectional device with no polarity marking; terminals are matte tin-plated leads, solderable per J-STD-002 and JESD 22-B102, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Identical bidirectional avalanche junction - either terminal serves as anode or cathode depending on instantaneous polarity; eliminates orientation concerns during placement. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood use including temperature cycling, humidity bias, and mechanical shock - enables drop-in deployment in ADAS, body control modules, and infotainment power supplies. |
| 600 W peak pulse power (10/1000 μs) | Withstands repeated IEC 61000-4-5 surges up to 4 kV (line-to-earth) without degradation, reducing need for redundant protection stages. |

| Telecom Power Supply Input Protection | Consumer Appliance Motor Drive Snubbing |
|
Use Scenario: Secondary-side DC bus protection in PoE-powered switches where 220 V-rated TVS absorbs induced surges from Ethernet cable coupling. IC Role / Device Role / Timing Role: Standoff-clamp device placed between +54 V DC output and ground, sized to handle 600 W short-duration spikes. Use Value: Prevents overvoltage failure of DC-DC controllers (e.g., MPQ4572) by limiting bus voltage to ≤328 V during lightning-induced transients per IEC 61000-4-5. |
Use Scenario: Suppressing inductive kickback from brushed DC motors in smart home vacuum cleaners and power tools. IC Role / Device Role / Timing Role: Parallel clamp across motor terminals to absorb energy from L·di/dt spikes during PWM commutation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ220CA | Same VWM/VBR/VC ratings but lower PPPM (400 W); SMA package (smaller footprint, higher RθJA = 150 °C/W). | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 compliance without parallel devices. | Select when board space is constrained and surge energy remains below 400 W, e.g., consumer USB-C PD protection. |
| 1.5KE220CA | Through-hole DO-201 package; same 220 V bidirectional rating but higher PPPM (1500 W); larger thermal mass and slower assembly. | Better suited for high-energy industrial mains input protection where manual assembly or wave soldering is used. | Choose for legacy through-hole designs or where higher single-pulse energy absorption (>600 W) is required, accepting larger PCB area. |
Compared with SMAJ220CA and 1.5KE220CA, P6SMB220CAHE3/5B uniquely balances 600 W surge capacity, AEC-Q101 qualification, and SMB footprint - making it the optimal choice for automotive-grade SMT production where reliability, power density, and process compatibility are jointly prioritized.

FAQ
What is the clamping voltage of P6SMB220CAHE3/5B at its rated peak pulse current?
The P6SMB220CAHE3/5B has a maximum clamping voltage (VC) of 328 V at a peak pulse current (IPPM) of 1.8 A under the standard 10/1000 μs waveform. This value is measured per Figure 1 in Vishay's datasheet 88370 and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream components like 250 V-rated capacitors or 300 V MOSFETs remain within safe operating limits.
Is P6SMB220CAHE3/5B suitable for automotive applications?
Yes, P6SMB220CAHE3/5B is AEC-Q101 qualified (indicated by the "HE3" suffix and "_B" revision code per datasheet note), making it suitable for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. Its MSL Level 1 rating, 150 °C junction temperature capability, and validated performance across temperature cycling and humidity bias ensure compliance with automotive reliability standards.
How does the bidirectional configuration of P6SMB220CAHE3/5B affect its circuit implementation?
The bidirectional configuration of P6SMB220CAHE3/5B means it provides identical clamping behavior in both polarities - no cathode band marking is present, and either terminal functions as anode or cathode depending on instantaneous voltage polarity. This simplifies PCB layout for AC-coupled lines (e.g., CAN, RS-485) and eliminates orientation errors during automated assembly, unlike unidirectional variants such as P6SMB220AHE3/5B.
What is the thermal resistance from junction to lead (RθJL) for P6SMB220CAHE3/5B?
The P6SMB220CAHE3/5B has a typical thermal resistance from junction to lead (RθJL) of 20 °C/W, as specified in the Thermal Characteristics table of Vishay's datasheet 88370. This low value enables efficient heat transfer to PCB copper pads during repetitive surge events, supporting sustained operation at elevated ambient temperatures without external heatsinking - especially important in compact automotive modules with limited airflow.
Does P6SMB220CAHE3/5B require special handling or baking before reflow soldering?
No, P6SMB220CAHE3/5B is rated MSL Level 1 per J-STD-020, with a maximum peak reflow temperature of 260 °C. It does not require dry pack storage or pre-reflow baking, even after extended exposure to ambient conditions - significantly simplifying SMT line logistics and reducing risk of moisture-related defects such as popcorning during reflow.
