Product details
Overview
P6SMB480AHM3_C/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 in power rails and signal lines. It features a 480 V standoff voltage (VWM), 504 V minimum breakdown voltage (VBR), 658 V maximum clamping voltage (VC) at 0.91 A peak pulse current (IPPM), and 600 W peak pulse power capability with a 10/1000 μs waveform.
For engineers reviewing the P6SMB480AHM3_C/I datasheet, P6SMB480AHM3_C/I pinout, P6SMB480AHM3_C/I application, or P6SMB480AHM3_C/I equivalent, key selection considerations include its AEC-Q101 qualification (HM3 suffix), halogen-free RoHS compliance, SMB (DO-214AA) package, unidirectional polarity with cathode band marking, and suitability for automotive and industrial overvoltage protection where high clamping ratio and low leakage (<1 μA at VWM) are critical.
Technical Context
This TVS diode operates as a unidirectional clamping device, leveraging an avalanche breakdown mechanism to limit transient voltages above its VBR threshold while maintaining low leakage below VWM. Its thermal resistance (RθJA = 100 °C/W) and junction temperature range (–65 °C to +150 °C) support reliable operation under repetitive surge conditions with 0.01% duty cycle.
The device is optimized for fast response (sub-nanosecond), low incremental surge resistance, and stable clamping performance across temperature - enabled by glass passivated chip junction and MSL Level 1 moisture sensitivity rating (peak reflow ≤260 °C). It meets JESD201 Class 2 whisker resistance and solderability per J-STD-002/JESD22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 408 V - Maximum continuous reverse operating voltage before clamping initiates; defines safe DC/AC rail margin. |
| VBR (Breakdown Voltage) | 456–504 V at 1 mA - Avalanche onset range; ensures predictable, repeatable clamping initiation under transients. |
| VC (Clamping Voltage) | 658 V at IPPM = 0.91 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines downstream component stress. |
| PPPM (Peak Pulse Power) | 600 W - Energy-handling capacity for standardized 10/1000 μs waveform; enables robust protection against lightning/inductive spikes. |
| ID (Reverse Leakage) | <1 μA at 408 V - Negligible standby current; avoids power loss or false triggering in high-impedance circuits. |
| TJ max. | +150 °C - Maximum junction temperature; supports operation in under-hood automotive and industrial environments. |
| Package | SMB (DO-214AA) - Low-profile SMD outline (5.59 mm × 4.06 mm × 2.20 mm); compatible with automated placement and reflow. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, unidirectional configuration with cathode indicated by a band on the case. Dimensions: 5.59 mm × 4.06 mm × 2.20 mm. Matte tin-plated leads, solderable per J-STD-002 and JESD22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground when voltage exceeds VBR. |
| Anode | Reference / return path | Typically tied to system ground or low-impedance return; completes clamping path during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified (HM3 suffix) | Validated for automotive applications including engine control units and body electronics; supports long-term reliability under thermal cycling and vibration. |
| Halogen-free & RoHS-compliant | Meets environmental compliance requirements for modern industrial and consumer electronics without compromising surge performance. |
| 600 W peak pulse power (10/1000 μs) | Handles high-energy transients from inductive switching or ESD coupling without degradation; suitable for 24 V/48 V industrial bus protection. |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage overshoot during clamping; reduces stress on downstream MOSFETs, controllers, and interface ICs. |
| MSL Level 1 (260 °C peak reflow) | Enables single-pass lead-free reflow assembly without moisture-related delamination or popcorn failure. |

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/VBR/VC specs but in SMA package (DO-214AC); lower PPPM (400 W); non-AEC-Q101; RoHS-compliant only. | Limited to commercial-grade industrial or consumer use; not rated for automotive under-hood environments. | Select when cost or board space permits larger footprint and AEC-Q101 is unnecessary. |
| 1.5KE480A | Through-hole (DO-201AD); identical electrical specs; higher RθJA (70 °C/W); no AEC-Q101 or halogen-free certification. | Suitable for prototyping or legacy through-hole designs; incompatible with automated SMT assembly. | Choose only for manual assembly or retrofit scenarios where SMB footprint is unavailable. |
Compared with SMAJ480A-E3/5B and 1.5KE480A, P6SMB480AHM3_C/I uniquely combines AEC-Q101 qualification, halogen-free construction, SMB footprint, and 600 W surge rating - making it the sole option for production automotive SMT designs requiring full compliance and high-energy clamping in minimal area.

FAQ
What is the clamping voltage of P6SMB480AHM3_C/I at its rated peak pulse current?
The P6SMB480AHM3_C/I has a maximum clamping voltage (VC) of 658 V at its specified peak pulse current (IPPM) of 0.91 A, measured using the standard 10/1000 μs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events and is confirmed in the Vishay P6SMB datasheet revision 09-Jan-2024, page 2.
Is P6SMB480AHM3_C/I qualified for automotive applications?
Yes, P6SMB480AHM3_C/I is AEC-Q101 qualified, as indicated by the "HM3" suffix and documented in the Vishay P6SMB datasheet (page 3, Note 2). The HM3 variant denotes halogen-free, RoHS-compliant, and AEC-Q101 qualified construction - validated for use in automotive powertrain, chassis, and body electronics where reliability under thermal cycling and vibration is mandatory.
What does the "C/I" suffix mean in P6SMB480AHM3_C/I?
The "C/I" suffix in P6SMB480AHM3_C/I specifies packaging and reel configuration: "C" indicates tape-and-reel delivery in 13-inch diameter reels, and "I" denotes the standard industry carrier tape width (typically 12 mm) and orientation per EIA-481. This matches Vishay's ordering code convention shown in the P6SMB datasheet page 3, where "/I" corresponds to 13″ reels with standard sprocket pitch.
What is the maximum operating junction temperature for P6SMB480AHM3_C/I?
The maximum operating junction temperature (TJ max.) for P6SMB480AHM3_C/I is +150 °C, as specified in the "Maximum Ratings" table on page 1 of the Vishay P6SMB datasheet. This rating enables reliable operation in under-hood automotive environments and high-temperature industrial enclosures without derating up to ambient temperatures of +85 °C under typical PCB layout conditions.
How does the SMB (DO-214AA) package of P6SMB480AHM3_C/I compare to SMA (DO-214AC) in thermal performance?
P6SMB480AHM3_C/I in SMB (DO-214AA) has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W, whereas SMA-packaged equivalents like SMAJ480A-E3/5B typically exhibit ~125 °C/W. The SMB's slightly larger copper pad area (0.2″ × 0.2″ recommended) and lower RθJA support better heat dissipation during repetitive surge events - critical for sustained operation in automotive and industrial applications.
