Product details
Overview
P6SMB220H from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a breakdown voltage range of 198–242 V, clamping voltage of 342 V at 1.8 A peak pulse current, and stand-off voltage of 175 V. It features AEC-Q101 qualification, glass passivated junction, and meets ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive load-dump and EFT immunity.
For engineers reviewing the P6SMB220H datasheet, P6SMB220H pinout, P6SMB220H application, or P6SMB220H equivalent, key selection criteria include its 175 V working voltage, 342 V clamping performance under 10/1000 µs surge, DO-214AA (SMB) package compatibility, and suitability for high-voltage DC bus protection in automotive power electronics and industrial control systems.
Technical Context
The P6SMB220H operates as a unidirectional avalanche diode, designed to clamp transient overvoltages above its 198–242 V breakdown threshold while maintaining low leakage (<1 µA at 175 V). Its fast response time (<1.0 ps from 0 V to VBR(min)) enables protection against nanosecond-scale ESD and EFT events.
Thermally, it supports operation from –55 °C to +150 °C, with junction-to-ambient thermal resistance of 55 °C/W and junction-to-case resistance of 10 °C/W. The device uses a single-die DO-214AA (SMB) package with matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance.
Key Specifications

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 220 V nominal breakdown, but rated at 600 W with slightly higher VC = 353 V @ 1.7 A | Marginally lower clamping ratio (VC/VBR(min) = 1.78 vs. 1.73 for P6SMB220H), affecting downstream voltage headroom | Select when legacy design uses SMBJ series and board layout allows minor clamping voltage trade-off |
| 1.5SMC220A | Higher power rating (1500 W), larger DO-214AB (SMC) package, VC = 353 V @ 4.2 A | Not drop-in: requires PCB footprint change and increased board area; suited for higher-energy surge environments | Choose only if system-level surge testing exceeds IEC 61000-4-5 Level 4 and existing layout permits SMC footprint |
Compared with SMBJ220A and 1.5SMC220A, the P6SMB220H offers tighter clamping (342 V), lower thermal resistance (55 °C/W), and AEC-Q101 qualification-making it optimal for space-constrained, automotive-grade 24 V/48 V systems where voltage margin and reliability are prioritized over raw energy handling.

FAQ
What is the breakdown voltage tolerance for P6SMB220H?
The P6SMB220H has a specified breakdown voltage range of 198 V to 242 V at 1.0 mA test current, corresponding to ±10% tolerance around the nominal 220 V rating. This tolerance is confirmed in the Electrical Specifications table on page 3 of the official TSC datasheet (Version A2102), and applies strictly under the defined test conditions of 30 ms square-wave pulse or equivalent.
Is P6SMB220H unidirectional or bidirectional?
P6SMB220H is a unidirectional TVS diode, as indicated by its "H" suffix (not "CH" or "CAH") and cathode-band marking per the DO-214AA package diagram. Its forward voltage is specified at 5.0 V @ 50 A, confirming unidirectional conduction behavior. Bidirectional variants require explicit CH/CAH suffixes and exhibit symmetrical VBR in both polarities.
What is the maximum clamping voltage of P6SMB220H under standard surge conditions?
The maximum clamping voltage of P6SMB220H is 342 V when subjected to its rated peak pulse current of 1.8 A under the standardized 10/1000 µs double-exponential waveform. This value is measured at the device terminals and represents the upper limit of voltage imposed on protected circuitry during worst-case transient events per IEC 61000-4-5 and ISO 7637-2.
Does P6SMB220H meet automotive qualification standards?
Yes, P6SMB220H is explicitly AEC-Q101 qualified per the manufacturer's documentation, and additionally meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b test requirements for automotive electrical disturbances. Its construction-including glass passivated junction, MSL Level 1 rating, and –55 °C to +150 °C operating range-supports deployment in engine control, body electronics, and ADAS subsystems.
What is the thermal resistance specification for P6SMB220H?
P6SMB220H has a junction-to-ambient thermal resistance (RθJA) of 55 °C/W and a junction-to-case thermal resistance (RθJC) of 10 °C/W, as published in the Thermal Performance section of the TSC datasheet. These values assume standard JEDEC high-K board conditions and define the device's ability to dissipate heat during sustained surge events or elevated ambient temperatures.
