Product details
Overview
P6SMB480A01HM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for high-energy surge protection on DC power rails and signal lines. It features a 480 V standoff voltage (VWM), 504 V minimum breakdown voltage (VBR), 600 W peak pulse power rating (10/1000 μs), and clamps transients to ≤658 V at 0.91 A peak pulse current - deployed in industrial motor drives and telecom power supplies.
For engineers reviewing the P6SMB480A01HM3_A/I datasheet, P6SMB480A01HM3_A/I pinout, P6SMB480A01HM3_A/I application, or P6SMB480A01HM3_A/I equivalent, key selection criteria include its 480 V VWM rating, unidirectional polarity with cathode band marking, SMB (DO-214AA) package compatibility, and AEC-Q101 qualification status indicated by the HM3 suffix.
Technical Context
This TVS diode operates as a clamping device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold (VBR = 456–504 V), limiting transient energy to protect downstream components. Its low incremental surge resistance and fast response time ensure effective suppression of lightning-induced surges and inductive switching spikes.
The device is rated for 600 W peak pulse power under the standardized 10/1000 μs waveform, with thermal resistance RθJA = 100 °C/W and maximum junction temperature of +150 °C. It is halogen-free, RoHS-compliant, and qualified to AEC-Q101 for automotive-grade reliability.
Key Specifications

|---|---|
| VWM (Stand-off Voltage) | 480 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin. |
| VBR (Breakdown Voltage) | 456–504 V at 1 mA test current - Ensures consistent avalanche initiation across production lots. |
| VC (Clamping Voltage) | ≤658 V at IPPM = 0.91 A - Limits peak voltage seen by protected ICs during surge events. |
| PPPM (Peak Pulse Power) | 600 W (10/1000 μs waveform) - Specifies maximum transient energy absorption capability per pulse. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ480A-E3/5B | Same VWM (480 V), same SMB package, but non-AEC-Q101, commercial-grade (E3 suffix). | Lacks automotive qualification; suitable for industrial/commercial designs where AEC-Q101 is not mandated. | Select SMAJ480A-E3/5B if cost sensitivity outweighs automotive reliability requirements. |
| P6SMB480AHE3_D/I | Same electrical specs and SMB package, but HE3 (RoHS-compliant, AEC-Q101) instead of HM3 (halogen-free + AEC-Q101). | Not halogen-free; may not meet strict automotive material compliance (e.g., GMW3172, Ford WSS-M99P9999-A1). | Choose P6SMB480AHE3_D/I only if halogen-free content is not required by OEM specification. |
Compared with P6SMB480A01HM3_A/I, SMAJ480A-E3/5B offers identical clamping performance at lower cost but lacks automotive qualification, while P6SMB480AHE3_D/I meets AEC-Q101 yet omits halogen-free compliance - making P6SMB480A01HM3_A/I the sole option satisfying both requirements simultaneously.

FAQ
What is the maximum clamping voltage of the P6SMB480A01HM3_A/I under surge conditions?
The P6SMB480A01HM3_A/I has a maximum clamping voltage (VC) of 658 V at its rated peak pulse current (IPPM) of 0.91 A, measured using the standard 10/1000 μs waveform. This value is guaranteed per the Vishay datasheet revision 09-Jan-2024 and defines the upper voltage limit imposed on protected circuitry during transient events. The P6SMB480A01HM3_A/I maintains this clamping performance across its specified operating temperature range.
Is the P6SMB480A01HM3_A/I suitable for automotive applications?
Yes, the P6SMB480A01HM3_A/I is AEC-Q101 qualified, as confirmed by the HM3 suffix in its part number and documented in Vishay's official P6SMB series datasheet. It meets automotive reliability requirements including temperature cycling, humidity testing, and mechanical shock. The P6SMB480A01HM3_A/I is intended for use in body control modules, infotainment power supplies, and other automotive subsystems where high-voltage transient suppression is needed.
What does the "HM3" suffix indicate in P6SMB480A01HM3_A/I?
The "HM3" suffix in P6SMB480A01HM3_A/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. Specifically, "H" indicates AEC-Q101 qualification, "M" signifies halogen-free materials, and "3" confirms RoHS compliance. This distinguishes it from E3 (RoHS only) and HE3 (RoHS + AEC-Q101, but not halogen-free) variants. The P6SMB480A01HM3_A/I thus satisfies stringent automotive material content requirements.
Can the P6SMB480A01HM3_A/I be used in bidirectional configurations?
No, the P6SMB480A01HM3_A/I is a unidirectional TVS diode, as indicated by the "A" (not "CA") in its part number and confirmed by its cathode band marking. Bidirectional versions use the "CA" suffix (e.g., P6SMB480CA). Using the P6SMB480A01HM3_A/I in bidirectional applications would result in forward conduction during negative transients, potentially causing failure. For bidirectional protection, select a verified CA-suffix variant.
What is the thermal resistance and power derating behavior of the P6SMB480A01HM3_A/I?
The P6SMB480A01HM3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on the recommended 0.2" × 0.2" copper pads. Its 600 W peak pulse power rating applies only at TA = 25 °C; power must be derated linearly above this temperature per Figure 2 in the Vishay datasheet, reaching zero at TJ = 150 °C. Continuous power dissipation (PD) is limited to 5.0 W at TA = 50 °C on an infinite heatsink.
