Product details
Overview
P6SMB13CAHM3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 13 V standoff voltage (VWM), 18.2 V maximum clamping voltage at 33.0 A peak pulse current, and 600 W peak pulse power capability with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial electronics.
For engineers reviewing the P6SMB13CAHM3_A/H datasheet, P6SMB13CAHM3_A/H pinout, P6SMB13CAHM3_A/H application, or P6SMB13CAHM3_A/H equivalent, key selection criteria include bidirectional clamping behavior, AEC-Q101 qualification status, 18.2 V VC rating at rated IPPM, thermal resistance (RθJA = 100 °C/W), and halogen-free RoHS compliance per HM3 suffix.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal paths without polarity sensitivity. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<5 μA at VWM), while the 10/1000 μs surge rating reflects standardized lightning and switching transient immunity testing.
The device is rated for continuous operation up to +150 °C junction temperature and meets J-STD-020 MSL Level 1 moisture sensitivity with 260 °C reflow peak. Its SMB package supports automated placement and provides 5.0 mm × 5.0 mm copper pad thermal dissipation per terminal, critical for sustaining repetitive surge events at 0.01% duty cycle.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 11.1 V - Maximum reverse voltage before significant conduction; defines operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 12.4 V to 13.7 V at 1.0 mA - Confirmed avalanche onset range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 18.2 V at 33.0 A IPPM - Peak voltage seen by protected circuit during 10/1000 μs transient; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capacity under standardized surge waveform; validates robustness against IEC 61000-4-5 surges. |
| ID (Reverse Leakage) | <5.0 μA at 11.1 V - Minimal standby current; avoids signal distortion or battery drain in low-power sensor interfaces. |
| TJ max. | +150 °C - Maximum allowable junction temperature; enables deployment in under-hood automotive or high-ambient industrial environments. |
| Package | SMB (DO-214AA) - Surface-mount outline with 2.2 mm height and 3.94 mm length; compatible with standard SMT pick-and-place and reflow profiles. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Terminals are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13CA | Same VWM (11.1 V) and VC (18.2 V), but lower PPPM (400 W); SMA package (smaller footprint, higher RθJA) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 or automotive load-dump scenarios | Select when board space is constrained and surge threat level is limited to IEC 61000-4-2 ESD only. |
| 1.5KE13CA | Higher PPPM (1500 W), axial-leaded DO-201 package; larger size, manual assembly only | Better thermal mass for repetitive surges, but incompatible with automated SMT lines and dense PCB layouts | Choose for prototyping or low-volume industrial power supplies where hand-soldering is acceptable and peak power exceeds 600 W. |
Compared with SMAJ13CA and 1.5KE13CA, P6SMB13CAHM3_A/H uniquely balances 600 W surge capability, AEC-Q101 qualification, halogen-free compliance, and SMB package compatibility with high-speed SMT assembly - making it optimal for volume automotive and industrial designs requiring validated reliability and process efficiency.

FAQ
What is the clamping voltage of P6SMB13CAHM3_A/H at its rated peak pulse current?
The P6SMB13CAHM3_A/H has a maximum clamping voltage (VC) of 18.2 V at 33.0 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured per standard test methods and defines the upper voltage limit imposed on protected circuitry during surge events. The P6SMB13CAHM3_A/H maintains this clamping performance across its specified operating temperature range and is validated per JEDEC and IEC standards.
Is P6SMB13CAHM3_A/H suitable for automotive applications?
Yes, P6SMB13CAHM3_A/H is AEC-Q101 qualified (denoted by the HM3 suffix) and specifically designed for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its construction meets stringent requirements for thermal cycling, mechanical shock, and long-term reliability under under-hood conditions. The P6SMB13CAHM3_A/H also complies with halogen-free and RoHS directives required by major Tier 1 suppliers.
How does the bidirectional configuration of P6SMB13CAHM3_A/H affect PCB layout?
The bidirectional nature of P6SMB13CAHM3_A/H eliminates polarity marking and allows placement without regard to anode/cathode orientation - simplifying layout for differential or AC-coupled lines like CAN, RS-485, or audio interfaces. Unlike unidirectional TVS diodes, the P6SMB13CAHM3_A/H provides symmetrical clamping in both voltage polarities, reducing design risk and eliminating orientation-related assembly errors in high-volume manufacturing.
What is the thermal resistance of P6SMB13CAHM3_A/H, and how does it impact power derating?
P6SMB13CAHM3_A/H 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. This value directly governs power derating above 25 °C ambient: for example, at 85 °C ambient, the device's safe continuous power dissipation drops to approximately 2.0 W. The P6SMB13CAHM3_A/H datasheet provides precise derating curves (Fig. 2) to ensure thermal stability under real-world operating conditions.
Does P6SMB13CAHM3_A/H require special handling during reflow soldering?
No special handling is required for P6SMB13CAHM3_A/H beyond standard SMT practices: it is rated MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C. The P6SMB13CAHM3_A/H can be processed in a single lead-free reflow profile without pre-baking, making it compatible with high-throughput automated assembly lines. Its matte tin-plated terminals ensure reliable wetting and joint formation per J-STD-002.
