Product details
Overview
P6SMB220C from Taiwan Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, rated for 600W peak pulse power, 220V breakdown voltage (VBR = 198–242 V), and clamping voltage of 342 V at 1.8 A peak pulse current. It protects DC power rails in industrial switching mode power supplies against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the P6SMB220C datasheet, P6SMB220C pinout, P6SMB220C application, or P6SMB220C equivalent, key selection criteria include unidirectional/bidirectional configuration (C suffix = bidirectional), clamping performance under 10/1000 µs surge, junction temperature limits (−55°C to +150°C), and compatibility with automated SMT placement on SMB footprint.
Technical Context
The P6SMB220C implements a glass-passivated silicon avalanche junction optimized for fast transient response (<1.0 ps rise time from 0 V to VBR min) and low leakage (<1 µA at 175 V stand-off). Its bipolar construction enables symmetrical clamping in both directions without polarity dependency.
Thermal design relies on RθJC = 10°C/W and RθJA = 55°C/W, supporting operation up to 150°C junction temperature. The device meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements for PCB-mounted surge protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 198 V / 242 V - ensures reliable avalanche conduction onset across manufacturing tolerance and temperature |
| VWM | 175 V - maximum continuous reverse working voltage before significant leakage begins |
| VC @ IPPM | 342 V at 1.8 A - clamped voltage during 10/1000 µs surge, defining protected circuit's maximum overvoltage stress |
| PPPSM | 600 W - non-repetitive peak pulse power handling per single transient event |
| IR @ VWM | <1 µA - minimal standby power loss and signal integrity impact in high-impedance monitoring circuits |
| TJ range | −55°C to +150°C - supports deployment in automotive engine compartments and industrial enclosures |
| Package | DO-214AA (SMB) - standardized 2-pin SMT outline with cathode band marking and 0.090 g mass |
Pinout & Package
DO-214AA (SMB) surface-mount package with molded epoxy body, matte tin-plated leads, and cathode band marking for polarity identification. Bidirectional operation means both terminals are functionally symmetric; no anode/cathode distinction applies in circuit use.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Transient input/output node | Connected across protected line and ground (or between differential lines); carries full surge current during clamping |
| Terminal 2 | Transient input/output node | Second connection point for bidirectional clamping; identical electrical role to Terminal 1 |
Key Features

IC Role / Device Role / Timing Role: TVS diode placed across input terminals to clamp surges before they reach upstream EMI filter and primary-side controller. Use Value: Withstands 600 W pulses while limiting voltage to ≤342 V, preventing damage to 400 V-rated bulk capacitors and MOSFETs. |
Use Scenario: LIN bus or sensor supply rail in BCM subjected to ISO 7637-2 Pulse 2a (battery disconnection) and Pulse 3b (ignition noise). IC Role / Device Role / Timing Role: Bidirectional clamping element referenced to chassis ground, protecting microcontroller I/O and analog front-end inputs. Use Value: Symmetrical 342 V clamping in both polarities eliminates need for dual unidirectional devices and reduces BOM count. |
| Commercial Display Power Input | Telecom AC/DC Adapter Output |
Use Scenario: 48 V auxiliary power input of large-format LED display cabinet, subject to lightning-induced surges via long cable runs. IC Role / Device Role / Timing Role: First-line transient suppressor at board edge, coordinated with downstream MOV and gas discharge tube for staged protection. Use Value: Low leakage (<1 µA) avoids loading 48 V standby rail; SMB footprint enables dense layout near connector. |
Use Scenario: Secondary-side 12 V output of wall-mounted AC/DC adapter used in VoIP phones and IP cameras. IC Role / Device Role / Timing Role: Final-stage TVS on regulated output to suppress coupling from primary-side switching noise and external ESD events. Use Value: Clamps to 342 V without forward conduction - critical for preserving regulation integrity during fast transients. |
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 DO-214AA package, identical 220 V VBR range and 600 W rating, but higher typical clamping voltage (350 V vs. 342 V) | Slightly higher clamping margin may be acceptable where protected ICs have >345 V absolute maximum ratings | Select SMBJ220CA only if existing design validation used this variant; P6SMB220C offers tighter clamping |
| 1.5SMC220CA | Higher 1500 W rating in larger DO-214AB (SMC) package; VBR 198–242 V, VC = 353 V @ 4.3 A | Used where higher single-pulse energy absorption is required, e.g., in main AC input stages with longer surge duration | Choose 1.5SMC220CA when system-level testing shows 600 W insufficient; requires PCB pad redesign due to larger footprint |
Compared with SMBJ220CA and 1.5SMC220CA, the P6SMB220C delivers the lowest clamping voltage (342 V) in the smallest standard SMB package, making it optimal for space-constrained secondary-side protection where precise voltage limiting is critical.

FAQ
What does the 'C' suffix indicate in P6SMB220C?
The 'C' suffix in P6SMB220C denotes bidirectional configuration, meaning the device provides symmetrical transient suppression in both polarities without requiring orientation during PCB assembly. Unlike unidirectional variants (e.g., P6SMB220A), the P6SMB220C has no anode or cathode - both terminals behave identically, enabling simplified layout in differential or floating rail applications. This is confirmed in the datasheet's "Devices for Bipolar Applications" section.
What is the maximum clamping voltage of P6SMB220C and under what test condition?
The maximum clamping voltage of P6SMB220C is 342 V, measured at a peak pulse current (IPPM) of 1.8 A using the standard 10/1000 µs double-exponential surge waveform. This value is specified in the Electrical Specifications table on page 3 of the official Taiwan Semiconductor datasheet (Version Q2209) and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Is P6SMB220C compliant with automotive transient standards?
Yes, P6SMB220C meets ISO 7637-2 requirements for Pulses 1, 2a, 2b, 3a, and 3b, as explicitly stated in the Features section of the datasheet. These pulses model real-world automotive electrical disturbances including load dump, battery disconnection, and ignition noise. Its 600 W rating and 342 V clamping make it suitable for 24 V system protection in body control modules and infotainment power supplies.
What is the thermal resistance profile of P6SMB220C and how does it affect PCB layout?
P6SMB220C has a junction-to-case thermal resistance (RθJC) of 10°C/W and junction-to-ambient (RθJA) of 55°C/W, per the Thermal Performance table. To maintain safe operation at 150°C max junction temperature, PCB copper area must be sufficient to dissipate heat during repetitive surges. Layout should include ≥25 mm² of 1 oz. copper connected to both terminals, avoiding narrow traces that increase thermal impedance and reduce surge endurance.
How does P6SMB220C compare to P6SMB220A in terms of electrical performance?
P6SMB220C is bidirectional with symmetrical VBR (198–242 V) and clamping in both directions, while P6SMB220A is unidirectional and intended for single-polarity DC rails. Their VBR, VWM, and VC values are identical, but P6SMB220A requires correct cathode orientation and cannot suppress negative-going transients. The P6SMB220C eliminates orientation risk and simplifies layout in AC-coupled or floating systems.
