Product details
Overview
P6SMB13CAHE3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on signal or power lines. It features a 13 V breakdown voltage (VBR min/max = 12.4–13.7 V at 1.0 mA), 11.1 V stand-off voltage (VWM), and clamps to ≤18.2 V at 33.0 A peak pulse current (10/1000 µs), delivering 600 W peak pulse power. It is AEC-Q101 qualified and used in automotive sensor line protection.
For engineers reviewing the P6SMB13CAHE3_A/H datasheet, P6SMB13CAHE3_A/H pinout, P6SMB13CAHE3_A/H application, or P6SMB13CAHE3_A/H equivalent, this device is selected for robust ESD and surge immunity in bidirectional DC rails-especially where automotive qualification, low clamping voltage, and SMB package compatibility are required.
Technical Context
The P6SMB13CAHE3_A/H operates as a symmetrical avalanche diode with identical forward and reverse characteristics due to its bidirectional construction. Its glass-passivated junction enables fast response (<1 ns) and stable clamping under repetitive 10/1000 µs transients at 0.01% duty cycle.
Thermal performance is defined by RθJA = 100 °C/W (typ.) and RθJL = 20 °C/W (typ.), with maximum junction temperature of +150 °C. It meets J-STD-020 MSL Level 1 and is rated for 100 A non-repetitive forward surge (8.3 ms half-sine) in unidirectional mode-though not applicable here due to bidirectional polarity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at IT = 1.0 mA - defines precise avalanche onset threshold for reliable transient detection |
| VWM | 11.1 V - maximum continuous reverse operating voltage before leakage exceeds 5.0 µA |
| VC @ IPPM | ≤18.2 V at 33.0 A (10/1000 µs) - clamping voltage limiting downstream IC stress during surge events |
| PPPM | 600 W - peak transient power handling capability under standardized surge waveform |
| IPPM | 33.0 A - maximum non-repetitive peak pulse current the device safely clamps without failure |
| Junction Temp Range | −65 °C to +150 °C - supports operation in under-hood automotive environments and industrial enclosures |
| Package | SMB (DO-214AA) - industry-standard surface-mount outline with 5.59 mm × 4.06 mm footprint and 2.20 mm height |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads; meets UL 94 V-0 flammability rating and J-STD-002 solderability requirements. Bidirectional configuration has no polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Terminal A | One side of symmetrical junction; functions identically as cathode under reverse bias in bidirectional operation |
| Cathode | Terminal B | Other side of symmetrical junction; interchangeable with Anode due to bidirectional symmetry |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13CA | Same VWM (11.1 V), lower PPPM (400 W), SMA package (smaller footprint, higher RθJA) | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a (load dump) | Select when board space is constrained and surge threat level is limited to IEC 61000-4-5 Level 2. |
| 1.5KE13CA | Same VWM/VC, higher PPPM (1500 W), axial DO-201 package (through-hole) | Requires PCB real estate and assembly change; incompatible with automated SMT lines | Choose only for legacy through-hole designs or where 1500 W headroom justifies manual assembly cost. |
Compared with SMAJ13CA and 1.5KE13CA, the P6SMB13CAHE3_A/H uniquely balances 600 W surge capacity, AEC-Q101 qualification, and SMB SMT compatibility-making it the optimal choice for new automotive and industrial SMT platforms requiring validated reliability and standardized placement.

FAQ
What is the maximum clamping voltage of the P6SMB13CAHE3_A/H under a 10/1000 µs surge?
The P6SMB13CAHE3_A/H clamps to a maximum of 18.2 V when subjected to its rated peak pulse current of 33.0 A with a 10/1000 µs waveform. This value is measured per standard test conditions (TA = 25 °C) and defines the upper voltage limit imposed on protected circuitry during transient events. The P6SMB13CAHE3_A/H maintains this clamping performance across its full operating temperature range, supporting design margin calculations for downstream ICs.
Is the P6SMB13CAHE3_A/H suitable for automotive applications?
Yes, the P6SMB13CAHE3_A/H is AEC-Q101 qualified and explicitly designated for automotive use with the "HE3" suffix indicating RoHS-compliant and AEC-Q101 qualified construction. It undergoes rigorous stress testing-including temperature cycling, highly accelerated life testing (HALT), and surge endurance-to meet automotive reliability requirements. The P6SMB13CAHE3_A/H is commonly deployed in engine control units, body electronics, and ADAS sensor interfaces where transient immunity is critical.
How does the bidirectional configuration of the P6SMB13CAHE3_A/H affect its circuit placement?
The bidirectional configuration of the P6SMB13CAHE3_A/H means it has no polarity marking and functions identically in both directions-ideal for protecting AC-coupled or differential signal lines like CAN, RS-485, or telecom pairs. Unlike unidirectional TVS diodes, the P6SMB13CAHE3_A/H can be placed without regard to orientation across terminals, simplifying layout and eliminating risk of reverse installation. This symmetry is intrinsic to its internal structure and verified in all electrical specifications.
What is the thermal resistance of the P6SMB13CAHE3_A/H, and how does it impact PCB layout?
The P6SMB13CAHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead resistance (RθJL) of 20 °C/W, measured on 0.2" × 0.2" copper pads per terminal. To maintain safe junction temperatures under repetitive surges, PCB layout must adhere to the recommended pad dimensions (minimum 0.086" × 0.060") and avoid excessive trace length or isolation. The P6SMB13CAHE3_A/H thermal performance is optimized for standard SMB land patterns without additional heatsinking.
Does the P6SMB13CAHE3_A/H have moisture sensitivity limitations for reflow soldering?
No-the P6SMB13CAHE3_A/H is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and may be subjected to standard lead-free reflow profiles (peak 260 °C) without pre-baking. This eliminates moisture-related defects such as popcorning and reduces manufacturing complexity. The P6SMB13CAHE3_A/H achieves this via hermetic molding compound and controlled internal humidity, confirmed in qualification testing.
