Product details
Overview
P6SMB220CAHE3_B/I 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), 252 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_B/I datasheet, P6SMB220CAHE3_B/I pinout, P6SMB220CAHE3_B/I application, or P6SMB220CAHE3_B/I 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 suitable for J-STD-002 soldering.
Technical Context
This device operates as a voltage-clamped transient protector with symmetrical bidirectional conduction-no polarity marking required-and delivers consistent clamping performance across both polarities due to its glass-passivated junction. Its 10/1000 μs waveform response supports IEC 61000-4-5 surge immunity up to Level 4.
Designed for surface-mount assembly on 0.2" × 0.2" copper pads per terminal, it achieves 600 W peak pulse power dissipation while maintaining TJ ≤ 150 °C under repetitive 0.01% duty cycle conditions. Thermal resistance from junction to lead (RθJL = 20 °C/W) enables effective heat transfer in compact PCB layouts without heatsinking.
Key Specifications

|---|---|
Use Scenario: Protecting LIN bus and sensor supply lines in door modules and lighting controllers from load dump and ESD. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed directly at connector entry to shunt transients before reaching MCU I/O or level translators. Use Value: Maintains signal integrity under ISO 7637-2 Pulse 5a (load dump) and IEC 61000-4-2 ESD (±15 kV air), preventing latch-up or damage to 3.3 V/5 V logic interfaces. |
Use Scenario: Safeguarding differential CANH/CANL lines in PLC gateways and motor drives exposed to field wiring surges. IC Role / Device Role / Timing Role: Low-capacitance bidirectional suppressor mounted across CAN bus pair to limit common-mode overvoltage without distorting data edges. Use Value: Clamps to ≤328 V during 10/1000 μs surges while adding <0.5 pF parasitic capacitance, preserving CAN FD bit rates up to 5 Mbps. |
| Telecom Power Supply Input Stage | Consumer Appliance Motor Driver Protection |
Use Scenario: Secondary-side DC input protection in PoE-powered switches and base station RF modules. IC Role / Device Role / Timing Role: Standoff-rated TVS placed after DC-DC converter output to absorb back-emf and induced surges from nearby AC mains switching. Use Value: Withstands repeated 600 W pulses at 0.01% duty cycle and maintains VWM = 220 V, enabling robust 24–48 V system designs compliant with EN 61000-4-5. |
Use Scenario: Suppressing commutation spikes from brushed DC motors in smart home appliances and HVAC blowers. IC Role / Device Role / Timing Role: Fast-response TVS connected across motor terminals to clamp inductive kickback before it reaches H-bridge MOSFETs or gate drivers. Use Value: Limits voltage overshoot to 328 V at 1.8 A peak, reducing MOSFET VDS stress and eliminating need for snubber RC networks in cost-sensitive designs. |
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) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 compliance | Select only when board space is constrained and surge energy is below 100 mJ |
| SMCJ220CA | Higher PPPM (1500 W), same VWM/VC, larger SMC package (DO-214AB), higher IFSM (100 A) | Better suited for primary-side AC/DC input protection where higher surge margin is required | Choose when protecting upstream rectifier stages or systems requiring >1000 W surge handling |
Compared with SMAJ220CA and SMCJ220CA, the P6SMB220CAHE3_B/I provides optimal balance of 600 W surge capacity, AEC-Q101 qualification, and SMB footprint-making it ideal for space-constrained automotive and industrial PCBs where full IEC 61000-4-5 compliance and long-term reliability are mandatory.

FAQ
What does the "CA" suffix indicate in P6SMB220CAHE3_B/I?
The "CA" suffix denotes that P6SMB220CAHE3_B/I is a bidirectional Transient Voltage Suppressor, meaning it provides symmetrical clamping for both positive and negative voltage transients without polarity orientation constraints. This eliminates the need for polarity marking on PCB silkscreen and simplifies layout for AC-coupled or floating signal paths, unlike unidirectional variants (e.g., P6SMB220A) which require cathode alignment.
Is P6SMB220CAHE3_B/I qualified for automotive use?
Yes, P6SMB220CAHE3_B/I carries the HE3_B suffix, confirming full AEC-Q101 qualification per Vishay's ordering documentation. It has undergone stress testing including temperature cycling, high-temperature reverse bias (HTRB), and ESD per AEC standards, making it suitable for under-hood and cabin applications such as body control modules, infotainment power rails, and ADAS sensor interfaces.
What is the maximum clamping voltage of P6SMB220CAHE3_B/I and how is it measured?
The maximum clamping voltage (VC) of P6SMB220CAHE3_B/I is 328 V, measured at a peak pulse current (IPPM) of 1.8 A using the standardized 10/1000 μs double-exponential surge waveform. This value represents the highest voltage imposed on the protected circuit during worst-case transient events and is validated per JEDEC/IEC test methods in Vishay's datasheet Figure 1 and Table on page 2.
Can P6SMB220CAHE3_B/I be used in place of a unidirectional TVS like P6SMB220A?
No-P6SMB220CAHE3_B/I is strictly bidirectional and cannot replace unidirectional P6SMB220A in circuits requiring forward conduction or DC bias blocking. While both share identical VWM (220 V) and VC (328 V), the unidirectional variant conducts only in reverse breakdown and blocks forward current, whereas P6SMB220CAHE3_B/I conducts equally in both directions, making it unsuitable for DC power rail protection where polarity must be preserved.
What packaging and reel options are available for P6SMB220CAHE3_B/I?
P6SMB220CAHE3_B/I is supplied in 13-inch diameter plastic tape and reel format (I-type carrier), with 3200 units per reel, as specified in Vishay's ordering information table. The "I" suffix explicitly denotes this large-reel configuration, optimized for high-volume SMT production. Tape pitch is 8 mm, and the device is packed per EIA-481 standards with humidity barrier bag and desiccant for MSL Level 1 handling.
