Product details
Overview
P6SMB130AHM3_B/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for robust overvoltage protection of sensitive electronics. It features a 130 V standoff voltage (VWM), 179 V maximum clamping voltage (VC) at 3.4 A peak pulse current (IPPM), and 600 W peak pulse power capability with a 10/1000 μs waveform - deployed on power rails and signal lines in automotive and industrial control modules.
For engineers reviewing the P6SMB130AHM3_B/I datasheet, P6SMB130AHM3_B/I pinout, P6SMB130AHM3_B/I application, or P6SMB130AHM3_B/I equivalent, key selection criteria include its AEC-Q101 qualification, SMB (DO-214AA) package compatibility, unidirectional polarity with cathode band marking, and thermal resistance (RθJA = 100 °C/W) under standard PCB pad layout conditions.
Technical Context
This TVS diode operates as a fast-acting shunt protector: when transient voltage exceeds its breakdown threshold (VBR min = 124 V, max = 137 V at 1 mA), it avalanches to clamp the line within nanoseconds. Its glass-passivated junction ensures stable leakage (<1 μA at VWM) and low incremental surge resistance, critical for protecting MOSFET gates and microcontroller I/Os against ESD and inductive switching spikes.
The device is rated for repetitive 10/1000 μs pulses at 0.01% duty cycle and supports peak forward surge current (IFSM) up to 100 A (8.3 ms half-sine). Its MSL Level 1 rating (260 °C peak reflow) and halogen-free, RoHS-compliant construction (HM3 suffix) meet automotive production requirements per JESD201 Class 2 whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 111 V - Maximum continuous reverse operating voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 124 V to 137 V at 1 mA - Voltage range at which avalanche conduction initiates; tight tolerance enables precise overvoltage trip point setting. |
| VC (Clamping Voltage) | 179 V at IPPM = 3.4 A - Maximum voltage seen by protected circuit during 10/1000 μs transient; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy-handling capacity under standardized surge waveform; validates suitability for IEC 61000-4-5 Level 3/4 transients. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on 0.2" × 0.2" copper pads; informs derating above 25 °C ambient for reliable long-term operation. |
| TJ max. | +150 °C - Maximum junction temperature; allows operation in under-hood automotive environments and high-power industrial enclosures. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing; required for ECUs, ADAS sensors, and body control modules. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode indicated by a band on the body; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink node | Connected to protected line (e.g., 12 V rail); conducts avalanche current to ground during overvoltage events. |
| Anode (unbanded end) | Reference / return path | Typically tied to system ground or low-impedance return plane; completes shunt path for transient energy dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Enables protection against severe load-dump and ISO 7637-2 Pulse 5a transients in 12 V automotive systems without external crowbar circuits. |
| AEC-Q101 qualified (HM3 suffix) | Validates reliability for automotive applications including engine control, infotainment, and lighting modules requiring zero field failures. |
| Low RθJA = 100 °C/W | Allows direct mounting on standard FR-4 PCBs with minimal copper area; eliminates need for heatsinks in space-constrained modules. |
| Glass-passivated junction | Ensures stable VBR and low leakage (<1 μA) across -65 °C to +150 °C; prevents parameter drift in harsh thermal environments. |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow profiles without preconditioning; simplifies manufacturing integration for high-volume SMT lines. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Clamping |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130A-E3/5B | Same VWM (111 V), VC = 185 V at 3.2 A; lower PPPM (400 W); non-AEC-Q101; SMA package (DO-214AC). | Limited to commercial-grade industrial and consumer equipment; not approved for automotive under-hood use. | Select when cost sensitivity outweighs automotive qualification and 200 W lower surge margin is acceptable. |
| 1.5SMC130A | Same VWM/VC specs; 1500 W PPPM; larger SMC (DO-214AB) package; AEC-Q101 available only in HM3 variant (1.5SMC130AHM3). | Higher power handling suits heavy-duty industrial motor drives but requires 30% more PCB area than SMB. | Choose for applications needing >600 W surge margin where board space permits larger footprint and higher IFSM (200 A). |
Compared with SMAJ130A-E3/5B, P6SMB130AHM3_B/I delivers AEC-Q101 compliance and superior thermal performance in a smaller SMB package; versus 1.5SMC130AHM3, it trades 900 W peak power for 35% smaller footprint and identical automotive qualification - ideal for space-constrained ECU designs.

FAQ
What is the clamping voltage of the P6SMB130AHM3_B/I under a 10/1000 μs surge?
The P6SMB130AHM3_B/I has a maximum clamping voltage (VC) of 179 V at a peak pulse current (IPPM) of 3.4 A with a 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88370 and defines the upper voltage limit imposed on protected circuitry during standardized surge events. The P6SMB130AHM3_B/I maintains this clamping performance across its specified operating temperature range.
Is the P6SMB130AHM3_B/I suitable for automotive applications?
Yes, the P6SMB130AHM3_B/I is AEC-Q101 qualified (denoted by the HM3 and _B suffixes), making it suitable for automotive applications including engine control units, body electronics, and ADAS sensor modules. Its construction meets JESD201 Class 2 whisker resistance, MSL Level 1 reflow compatibility, and operates reliably from –65 °C to +150 °C - all verified per AEC-Q101 test requirements. The P6SMB130AHM3_B/I is explicitly listed in Vishay's automotive-grade ordering matrix.
What does the "HM3_B/I" suffix mean in P6SMB130AHM3_B/I?
In P6SMB130AHM3_B/I, "HM3" indicates halogen-free, RoHS-compliant construction with AEC-Q101 qualification; "_B" denotes AEC-Q101 qualification level for the 6.8 V to 220 V voltage range; and "/I" specifies packaging in 13-inch tape-and-reel format with 3200 units per reel. This full suffix confirms the P6SMB130AHM3_B/I meets automotive reliability standards and is supplied in high-volume production-ready packaging.
How does the P6SMB130AHM3_B/I compare to bidirectional TVS diodes like P6SMB130CA?
The P6SMB130AHM3_B/I is unidirectional and features a cathode band for polarity-sensitive placement, whereas P6SMB130CA is bidirectional with no polarity marking and symmetric clamping in both directions. The P6SMB130AHM3_B/I offers lower leakage (<1 μA at 111 V) and is optimized for DC rail protection, while P6SMB130CA suits AC-coupled or differential signal lines. Their VWM, VBR, and VC values differ due to inherent architecture - the P6SMB130AHM3_B/I is not interchangeable with P6SMB130CA without circuit review.
What is the thermal resistance and recommended pad layout for the P6SMB130AHM3_B/I?
The P6SMB130AHM3_B/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as defined in Vishay datasheet 88370. The recommended pad layout matches the SMB (DO-214AA) outline: 0.086" minimum cathode/anode pad width, 0.220" overall length reference, and 0.060" minimum spacing between pads. Deviations reduce power derating capability and may compromise long-term reliability of the P6SMB130AHM3_B/I.
