Product details
Overview
P6SMB220A from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a breakdown voltage range of 209–231 V, stand-off voltage of 185 V, and clamping voltage of 328 V at 1.9 A peak pulse current. It features glass-passivated junction, <1 μA reverse leakage above 10 V, and sub-1 ps response time, deployed for surge protection in high-voltage DC power rails.
For engineers reviewing the P6SMB220A datasheet, P6SMB220A pinout, P6SMB220A application, or P6SMB220A equivalent, key selection criteria include its 185 V working voltage rating, 328 V clamping performance under 10/1000 μs transients, DO-214AA (SMB) package compatibility, and compliance with ISO 7637-2 Pulse 1/2a/2b/3a/3b automotive surge standards.
Technical Context
The P6SMB220A operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its minimum breakdown threshold of 209 V at 1 mA test current. Its clamping action limits transient energy to ≤328 V at 1.9 A, enabling robust protection of downstream 200 V-class power converters and industrial control inputs.
Thermal design relies on RθJA = 55 °C/W and RθJC = 10 °C/W, supporting continuous operation up to +150 °C junction temperature. The device meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1, ensuring reliability in automated SMT assembly.
Key Specifications

Applications
| Industrial Power Supply Input Protection | Automotive Body Control Module (BCM) Power Rail |
|---|---|
Use Scenario: 200 V DC input stage of DIN-rail mounted programmable logic controller (PLC) power supply exposed to lightning-induced surges on factory wiring. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between +200 V rail and chassis ground to clamp fast transients before they reach bulk capacitor and controller IC. Use Value: Limits voltage excursion to ≤328 V during 10/1000 μs surges, preventing damage to 250 V-rated electrolytic capacitors and 200 V MOSFETs in primary-side regulation. | Use Scenario: 12 V–24 V battery-fed BCM module subjected to load dump and alternator switching transients per ISO 7637-2. IC Role / Device Role / Timing Role: Standoff-rated TVS on main power input, activated only during >185 V events such as severe load dump spikes. Use Value: Provides secondary-stage overvoltage protection where primary TVS (e.g., P6SMB24A) may be undersized for extreme 120 V+ pulses, extending system robustness beyond basic compliance. |
| High-Voltage DC Motor Drive Gate Driver Supply | Telecom Rectifier Output Stage |
Use Scenario: Isolated 190 V auxiliary supply powering gate drivers in a 400 V three-phase inverter, subject to commutation-induced ringing and cross-talk. IC Role / Device Role / Timing Role: Clamping diode across isolated DC/DC converter output to suppress repetitive 200–250 V spikes coupled from motor phase legs. Use Value: Maintains driver supply integrity by limiting transients to 328 V, preventing latch-up or overvoltage failure in high-speed SiC gate drivers rated for 350 V absolute max. | Use Scenario: -48 V telecom rectifier output feeding distributed power architecture, requiring immunity to AC line transients propagated through transformer coupling. IC Role / Device Role / Timing Role: Bidirectional protection (using P6SMB220CA variant) across output terminals to absorb differential-mode surges exceeding ±185 V. Use Value: Enables use of same TVS family across both polarities without redesign, reducing BOM count while meeting GR-1089-CORE surge immunity requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220A | Same DO-214AA package, identical 209–231 V VBR, but lower 600 W PPPSM rating and higher 339 V VC at 1.9 A | Marginally higher clamping voltage reduces protected circuit margin; suitable only if 328 V vs. 339 V difference is acceptable | Select P6SMB220A when tighter clamping (328 V) is required for 250 V-rated downstream components |
| 1.5SMC220A | Higher 1500 W PPPSM, same VBR/VWM, but larger DO-214AB (SMC) package (7.11 × 6.22 mm vs. 4.57 × 3.94 mm) | Requires PCB layout change; preferred for systems needing higher single-pulse energy absorption | Choose P6SMB220A for space-constrained designs where 600 W rating suffices and SMB footprint is mandatory |
Compared with SMBJ220A and 1.5SMC220A, the P6SMB220A delivers the tightest clamping voltage in the SMB form factor while maintaining industry-standard surge ratings-making it optimal for compact, high-reliability 200 V DC protection where board area and voltage margin are critical constraints.

FAQ
What is the maximum clamping voltage of the P6SMB220A under standard 10/1000 μs surge conditions?
The P6SMB220A has a maximum clamping voltage (VC) of 328 V when subjected to its rated peak pulse current of 1.9 A using the standardized 10/1000 μs waveform. This value is measured at TA = 25°C and defines the upper voltage limit imposed on protected circuitry during transient events. Designers must ensure downstream components have sufficient voltage margin above this 328 V clamping level.
Is the P6SMB220A suitable for bidirectional transient suppression?
No-the P6SMB220A is a unidirectional TVS diode intended for DC line protection with defined anode/cathode polarity. For bidirectional applications, the P6SMB220CA variant must be used. Using P6SMB220A in reverse-biased AC configurations risks permanent failure due to lack of symmetrical breakdown characteristics.
What is the reverse leakage current specification for the P6SMB220A at its stand-off voltage?
At its rated stand-off voltage (VWM) of 185 V, the P6SMB220A exhibits a maximum reverse leakage current (IR) of less than 1 μA at TA = 25°C. This ultra-low leakage minimizes power loss in high-impedance sensing or always-on monitoring circuits and ensures stable biasing in precision voltage reference paths.
Does the P6SMB220A comply with automotive surge immunity standards?
Yes-the P6SMB220A is explicitly rated to meet ISO 7637-2 test pulses 1, 2a, 2b, 3a, and 3b, making it suitable for protecting electronic control units (ECUs) and body electronics against conducted transients in 12 V and 24 V vehicle electrical systems. Its 185 V VWM and 328 V VC align with load-dump and supply interruption surge profiles.
What is the thermal resistance from junction to ambient for the P6SMB220A in standard PCB mounting?
The P6SMB220A has a typical junction-to-ambient thermal resistance (RθJA) of 55 °C/W when mounted on a standard FR-4 PCB with minimum copper pad area per JEDEC standards. This value assumes no added heatsinking; actual thermal performance improves significantly with increased copper pour or thermal vias, enabling sustained operation up to its +150 °C maximum junction temperature.
