Product details
Overview
P6SMB220AHE3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 220 V standoff voltage (VWM), 231 V minimum breakdown voltage (VBR), and 328 V maximum clamping voltage (VC) at 1.8 A peak pulse current (IPPM), designed to protect power rails and signal lines in industrial power supplies and automotive ECUs against lightning-induced surges and inductive switching transients.
For engineers reviewing the P6SMB220AHE3/52 datasheet, P6SMB220AHE3/52 pinout, P6SMB220AHE3/52 application, or P6SMB220AHE3/52 equivalent, key selection criteria include clamping performance under 10/1000 μs waveform, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), and compatibility with automated SMT assembly on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, leveraging glass-passivated junction technology for stable surge response and low incremental surge resistance. Its 600 W peak pulse power rating (10/1000 μs) is derated linearly above 25 °C ambient per Fig. 2, and it meets MSL Level 1 per J-STD-020 with 260 °C reflow peak temperature tolerance.
The device exhibits a +0.108 %/°C temperature coefficient of VBR and delivers 1.8 A IPPM at VC = 328 V, with 1.0 μA maximum reverse leakage at VWM = 185 V. It is qualified to AEC-Q101 for automotive applications and features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 185 V - Maximum continuous reverse operating voltage before clamping initiates; defines safe DC/AC rail protection threshold. |
| VBR (Breakdown Voltage) | 209–231 V at IT = 1.0 mA - Voltage at which device enters avalanche conduction; ensures precise overvoltage triggering margin. |
| VC (Clamping Voltage) | 328 V at IPPM = 1.8 A - Peak voltage seen by protected circuit during 10/1000 μs transient; determines downstream component stress level. |
| PPPM (Peak Pulse Power) | 600 W - Surge energy handling capability under standardized 10/1000 μs waveform; supports IEC 61000-4-5 Level 4 compliance. |
| ID (Reverse Leakage) | 1.0 μA max at VWM - Minimal quiescent current draw in standby; avoids unnecessary power loss or false triggering. |
| TJ max | 150 °C - Maximum junction temperature; sets thermal design limits for PCB copper pad sizing and airflow requirements. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; used to calculate temperature rise under steady-state PD = 5.0 W. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with UL 94 V-0 flammability rating; cathode identified by band marking on unidirectional variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to lower-potential side of protected line. | Defines polarity-sensitive placement-must be oriented toward ground or return path in unidirectional configuration. |
| Cathode | Current exit terminal in forward bias; marked with band; connected to higher-potential side (e.g., VBUS). | Ensures correct clamping direction: conducts only when cathode voltage exceeds anode by ≥VBR, diverting surge to ground. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness-enables use in engine control units and ADAS sensors. |
| Glass passivated junction | Provides stable avalanche characteristics over lifetime and improved moisture resistance versus epoxy-passivated alternatives. |
| MSL Level 1 rating | Supports lead-free reflow up to 260 °C peak without popcorn failure-compatible with standard SMT production lines. |
| 600 W 10/1000 μs pulse rating | Meets IEC 61000-4-5 surge immunity requirements for industrial equipment and telecom infrastructure interfaces. |
| Low clamping ratio (VC/VBR ≈ 1.42) | Minimizes overvoltage overshoot during fast transients-critical for protecting 200 V-rated MOSFETs and gate drivers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ220A-E3/52 | Same VWM (185 V), identical SMB package, but lower PPPM (400 W) and higher VC (356 V at 1.5 A). | Limited to lower-energy transients; not suitable for IEC 61000-4-5 Level 4 or automotive load dump. | Select only if system-level surge testing confirms <400 W requirement and layout allows tighter thermal management. |
| 1.5SMC220A | Higher package thermal mass (SMC/DO-214AB), same VWM/VC specs, but RθJA = 40 °C/W and 1500 W PPPM rating. | Better suited for high-repetition-rate surges or high-ambient environments where junction temperature must stay <125 °C. | Choose when board space permits larger SMC footprint and thermal performance outweighs SMT placement density constraints. |
Compared with SMAJ220A-E3/52, P6SMB220AHE3/52 delivers 50 % higher surge power headroom and tighter clamping; versus 1.5SMC220A, it trades thermal robustness for compact SMB footprint and AEC-Q101 qualification-making it optimal for space-constrained automotive and industrial modules.

FAQ
What is the clamping voltage of P6SMB220AHE3/52 at its rated peak pulse current?
The P6SMB220AHE3/52 has a maximum clamping voltage (VC) of 328 V at 1.8 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured with the device mounted on 0.2" × 0.2" copper pads per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The P6SMB220AHE3/52 maintains this clamping performance across its full operating junction temperature range of –65 °C to +150 °C.
Is P6SMB220AHE3/52 qualified for automotive applications?
Yes, P6SMB220AHE3/52 is AEC-Q101 qualified, as indicated by the "HE3" suffix in its part number. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and electrostatic discharge (ESD), confirming suitability for automotive powertrain and body electronics. The P6SMB220AHE3/52 is specifically rated for use in engine control units, body control modules, and ADAS sensor interfaces where reliability under thermal and electrical stress is critical.
What is the standoff voltage rating of P6SMB220AHE3/52, and how does it relate to system operating voltage?
The P6SMB220AHE3/52 has a maximum reverse standoff voltage (VWM) of 185 V, meaning it remains non-conductive up to this DC or RMS voltage level. For reliable operation, system nominal voltage must remain below VWM with margin-for example, it is commonly deployed on 150 V DC bus lines or 24 V automotive systems with load-dump protection. The P6SMB220AHE3/52 begins avalanche conduction at VBR (209–231 V), ensuring clean separation between normal operation and transient suppression.
Does P6SMB220AHE3/52 have a bidirectional variant, and how does polarity affect PCB layout?
No, P6SMB220AHE3/52 is strictly unidirectional, as confirmed by its "A" suffix and cathode-band marking. Bidirectional variants use "CA" suffixes (e.g., P6SMB220CA). The unidirectional nature requires correct orientation: cathode must connect to the higher-potential node (e.g., VBUS), anode to ground or return path. Reversing polarity prevents clamping action and risks catastrophic failure under overvoltage. The P6SMB220AHE3/52's polarity marking is essential for automated optical inspection and functional validation.
What thermal considerations apply when using P6SMB220AHE3/52 in high-power surge scenarios?
The P6SMB220AHE3/52 has a junction-to-ambient thermal resistance (RθJA) of 100 °C/W on standard 0.2" × 0.2" copper pads. Under repetitive surge conditions, average power dissipation must stay below 5.0 W (PD rating), and peak junction temperature must not exceed 150 °C. Derating curves in Fig. 2 show 1 % reduction in PPPM per 1 °C above 25 °C ambient. The P6SMB220AHE3/52 requires adequate copper area and airflow in applications with >0.01 % duty cycle to avoid thermal runaway.
