Product details
Overview
P6SMB130CAHM3/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 130 V standoff voltage (VWM), 179 V clamping voltage (VC) at 3.4 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 μs waveform). It protects signal lines and power rails in automotive sensor units, industrial I/O interfaces, and telecom front-end circuits against ESD and inductive switching transients.
For engineers reviewing the P6SMB130CAHM3/H datasheet, P6SMB130CAHM3/H pinout, P6SMB130CAHM3/H application, or P6SMB130CAHM3/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, halogen-free RoHS compliance, low thermal resistance (RθJL = 20 °C/W), and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
This TVS diode operates symmetrically in both directions, delivering consistent clamping performance across positive and negative transients without polarity sensitivity. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 μA at VWM), while the low incremental surge resistance enables rapid energy diversion during fast-rising ESD events (sub-nanosecond response).
The device is rated for 150 °C maximum junction temperature and meets J-STD-020 MSL Level 1 (260 °C peak reflow), supporting robust manufacturing integration. Its 600 W peak pulse rating applies under repetitive 0.01% duty cycle conditions with 10/1000 μs waveform, validated on 5.0 mm × 5.0 mm copper pads per terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 111 V - Maximum continuous reverse voltage before clamping begins; defines operating margin below breakdown. |
| VBR (Breakdown) | 124–137 V at 1.0 mA - Confirmed breakdown range ensures reliable triggering within specified tolerance band. |
| VC (Clamping) | 179 V at IPPM = 3.4 A - Peak voltage seen by protected circuit during worst-case transient; determines system overvoltage stress. |
| PPPM | 600 W (10/1000 μs) - Energy-handling capacity for standardized surge events; supports IEC 61000-4-5 Level 4 compliance. |
| ID (Leakage) | <1.0 μA at 111 V - Minimal standby current avoids loading sensitive analog or low-power logic inputs. |
| TJ max. | 150 °C - Enables operation in under-hood automotive or high-ambient industrial environments. |
| RθJL | 20 °C/W - Low junction-to-lead thermal resistance improves power dissipation efficiency during repeated surges. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, halogen-free, RoHS-compliant, matte tin-plated leads. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); recommended pad layout: 5.59 mm × 2.159 mm per terminal.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA | Same VWM (111 V), VC (179 V), and PPPM (600 W); differs in packaging code (no HM3 suffix) and lacks AEC-Q101 qualification. | Not qualified for automotive use; suitable for commercial/industrial designs where automotive reliability is not mandated. | Select SMBJ130CA when AEC-Q101 is unnecessary and cost optimization is prioritized over automotive traceability. |
| 1.5SMC130CA | Higher package thermal mass (SMC vs. SMB); same electrical specs but RθJA = 40 °C/W (vs. 100 °C/W for P6SMB130CAHM3/H) and larger footprint (7.11 mm × 6.22 mm). | Better suited for high-repetition-rate surges due to improved heat spreading; requires PCB area increase and layout revision. | Choose 1.5SMC130CA only if system-level thermal modeling confirms SMB package cannot sustain required surge duty cycle. |
Compared with SMBJ130CA and 1.5SMC130CA, P6SMB130CAHM3/H uniquely combines AEC-Q101 qualification, halogen-free construction, and SMB footprint-enabling drop-in replacement in automotive designs without compromising board space or regulatory compliance.

FAQ
What is the clamping voltage of P6SMB130CAHM3/H at its rated peak pulse current?
The P6SMB130CAHM3/H has a maximum clamping voltage (VC) of 179 V at 3.4 A peak pulse current (IPPM), measured under the standard 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during transient events and is confirmed in the Vishay datasheet Document Number 88370, page 2. The P6SMB130CAHM3/H maintains this clamping performance across its full operating temperature range (−65 °C to +150 °C).
Is P6SMB130CAHM3/H qualified for automotive applications?
Yes, P6SMB130CAHM3/H is AEC-Q101 qualified, as indicated by the "HM3" suffix and confirmed in the Vishay ordering information table (page 3 of Document 88370). It undergoes stress testing including temperature cycling, high-temperature reverse bias (HTRB), and ESD per the AEC-Q101 standard, making it suitable for under-hood and chassis-mounted automotive electronics where reliability under harsh conditions is mandatory.
What does the "CA" suffix signify in P6SMB130CAHM3/H?
The "CA" suffix in P6SMB130CAHM3/H denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., P6SMB130A), the CA version has no cathode marking and functions identically in either polarity-ideal for protecting AC-coupled signals, differential buses, or floating power rails where polarity reversal may occur.
What is the maximum operating temperature for P6SMB130CAHM3/H?
The P6SMB130CAHM3/H has a maximum junction temperature (TJ max.) of +150 °C, as specified in the "Maximum Ratings" table (page 1 of Document 88370). This rating allows reliable operation in high-ambient environments such as automotive engine compartments or industrial enclosures, provided PCB thermal design adheres to the recommended 5.0 mm × 5.0 mm copper pad layout per terminal to maintain thermal resistance limits.
How does the HM3 suffix differ from M3 or E3 in the P6SMB130CAHM3/H part number?
The "HM3" suffix in P6SMB130CAHM3/H indicates halogen-free, RoHS-compliant construction with AEC-Q101 qualification-distinguishing it from "M3" (halogen-free, RoHS, commercial grade only) and "E3" (RoHS-compliant, commercial grade, non-halogen-free). The "H" prefix in HM3 explicitly denotes automotive qualification, verified through Vishay's certified test reports and documented in the ordering information section of the datasheet.
