Product details
Overview
P6SMB220AH from Taiwan Semiconductor is a unidirectional 600W surface-mount Transient Voltage Suppressor (TVS) diode with a nominal breakdown voltage 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, AEC-Q101 qualification, and is designed for automotive and industrial ESD/inductive transient protection in DC power rails and signal lines.
For engineers reviewing the P6SMB220AH datasheet, P6SMB220AH pinout, P6SMB220AH application, or P6SMB220AH equivalent, this device is selected for high-voltage surge immunity where precise clamping, low leakage (<1 µA @ 185 V), and ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance are required in space-constrained SMB packages.
Technical Context
The P6SMB220AH operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 209–231 V breakdown range (tested at 1 mA). Its 328 V clamping voltage limits transient energy to protected circuitry during 10/1000 µs surges up to 600 W non-repetitive peak power.
Thermal performance is defined by RθJC = 10 °C/W and RθJA = 55 °C/W, enabling operation from –55 °C to +150 °C junction temperature. The DO-214AA (SMB) package supports automated placement and meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 209 V / 231 V - Ensures reliable triggering above 185 V operating rail while avoiding false conduction. |
| VWM | 185 V - Maximum continuous reverse working voltage; defines safe DC operating margin before clamping. |
| VC @ IPPM | 328 V @ 1.9 A - Clamping voltage under 10/1000 µs surge; determines maximum stress on downstream ICs. |
| PPPSM | 600 W - Peak pulse power handling capacity; validates robustness against ISO 7637-2 Pulse 1 & 2b transients. |
| IR @ VWM | <1 µA - Ultra-low reverse leakage ensures minimal standby power loss and signal integrity in high-impedance circuits. |
| TJ max | +150 °C - Enables use in under-hood automotive environments and thermally demanding industrial enclosures. |
| Package | DO-214AA (SMB) - Standardized 3.5 mm × 4.5 mm surface-mount footprint compatible with JEDEC MS-012AC. |
Pinout & Package
DO-214AA (SMB) package: Cathode-banded end denotes cathode terminal; anode is unmarked end. Matte tin-plated leads meet J-STD-002 solderability; polarity marking aligns with industry-standard unidirectional TVS orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for reverse-biased operation | Connected to system ground or lower-potential rail; forms return path during clamping. |
| Cathode | High-side transient sink | Connected to protected line (e.g., 24 V supply); conducts surge current to ground when VREV > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan. |
| Glass passivated junction | Enhances long-term stability and moisture resistance vs. epoxy-passivated alternatives; critical for under-hood longevity. |
| ISO 7637-2 compliance | Meets Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (line impedance coupling) requirements. |
| Low profile SMB package | 3.5 mm × 4.5 mm × 2.3 mm height enables dense PCB layouts without sacrificing thermal or surge performance. |
| Moisture sensitivity level 1 | No dry-pack or baking required prior to reflow; simplifies SMT manufacturing and reduces process risk. |
Applications
| Automotive Power Rail Protection | Industrial DC Input Surge Suppression |
|---|---|
Use Scenario: Protecting 24 V battery-fed ECUs from load dump and alternator transients in passenger vehicles. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and input filter capacitor to clamp ISO 7637-2 Pulse 5a (load dump) spikes. Use Value: Limits peak voltage to ≤328 V, preventing damage to upstream DC-DC controllers and microcontrollers rated for 36 V absolute max. |
Use Scenario: Safeguarding programmable logic controller (PLC) 24 V DC inputs against field-wiring induced surges. IC Role / Device Role / Timing Role: Standoff-clamp TVS on DIN-rail mounted I/O module power entry point, absorbing repetitive 1 kV/500 A transients. Use Value: Withstands ≥1000 surges at rated 600 W due to low thermal resistance (RθJA = 55 °C/W), ensuring field longevity. |
| LED Driver Overvoltage Clamp | Telecom Line Interface Protection |
Use Scenario: Preventing catastrophic failure of constant-current LED drivers exposed to accidental 48 V connection or lightning-induced surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp on driver input stage, placed ahead of bulk capacitor and controller IC. Use Value: 185 V VWM provides 20% margin over 150 V LED string forward voltage, while 328 V VC avoids controller latch-up. |
Use Scenario: Shielding RS-485 transceivers on outdoor telecom cabinets from induced surges on long twisted-pair runs. IC Role / Device Role / Timing Role: Secondary-level protection on DC bias rail feeding isolated RS-485 PHY, complementing primary gas discharge tube. Use Value: Sub-1 µA leakage preserves bias stability across wide temperature range (–55 °C to +150 °C), maintaining signal integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220A | Same DO-214AA package, identical VBR (209–231 V), but lower PPPSM = 600 W (same rating) and higher VC = 355 V @ 1.7 A. | Higher clamping voltage increases stress on protected ICs; less suitable for tight-margin 24 V systems. | Select P6SMB220AH when clamping voltage ≤328 V is mandatory for downstream component survival. |
| 1.5SMC220A | DO-214AB (SMC) package (larger: 7.1 mm × 6.2 mm), same electrical specs, but higher thermal mass and RθJA = 35 °C/W. | Better sustained surge handling but incompatible with SMB footprint; requires PCB redesign. | Choose P6SMB220AH for space-constrained designs where DO-214AA footprint and automated placement are essential. |
Compared with SMBJ220A and 1.5SMC220A, the P6SMB220AH delivers the lowest clamping voltage in the SMB form factor and maintains AEC-Q101 qualification without increasing board area-making it optimal for automotive and compact industrial modules.

FAQ
What is the breakdown voltage range of the P6SMB220AH?
The P6SMB220AH has a guaranteed breakdown voltage range of 209 V to 231 V at 1 mA test current, measured per ANSI/IEEE C62.35. This range ensures consistent triggering behavior across production lots and temperature extremes, supporting reliable overvoltage protection in 185 V-rated systems. The P6SMB220AH's tight 10% VBR tolerance minimizes design margin uncertainty.
Is the P6SMB220AH suitable for automotive applications?
Yes, the P6SMB220AH is AEC-Q101 qualified and explicitly tested for automotive-grade reliability, including temperature cycling, highly accelerated life testing (HALT), and ESD robustness. It meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b requirements-making the P6SMB220AH appropriate for engine control units, body control modules, and ADAS power supplies.
What is the clamping voltage of the P6SMB220AH under surge conditions?
The P6SMB220AH clamps to a maximum of 328 V when subjected to a 10/1000 µs waveform with a peak pulse current of 1.9 A. This value is specified in the datasheet's Electrical Specifications table and verified per JEDEC standards. The low clamping voltage of the P6SMB220AH directly protects downstream 36 V-rated ICs from destructive overvoltage events.
Does the P6SMB220AH have bidirectional capability?
No, the P6SMB220AH is a unidirectional TVS diode, indicated by the "H" suffix and absence of "CAH" in its part number. Bidirectional variants (e.g., P6SMB220CAH) exist in the same family but feature symmetrical breakdown in both polarities. The P6SMB220AH must be oriented with cathode toward the protected line and anode to ground for correct operation.
What package type does the P6SMB220AH use, and what are its key mechanical attributes?
The P6SMB220AH uses the DO-214AA (SMB) package: 3.5 mm × 4.5 mm body with 2.3 mm maximum height, matte tin-plated leads compliant with J-STD-002, and UL 94V-0 molding compound. Its low-profile design supports high-density PCB layouts, and the MSL Level 1 rating eliminates bake requirements-key advantages of the P6SMB220AH in automated SMT assembly.
