Product details
Overview
P6SMB13CAHE3_B/I 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 for ESD and surge protection in automotive sensor interfaces.
For engineers reviewing the P6SMB13CAHE3_B/I datasheet, P6SMB13CAHE3_B/I pinout, P6SMB13CAHE3_B/I application, or P6SMB13CAHE3_B/I equivalent, key selection criteria include bidirectional clamping capability, SMB (DO-214AA) package compatibility, 150 °C max junction temperature, low leakage (<5.0 μA at VWM), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VBR, VWM, IPPM, and VC specifications in forward and reverse directions. Its glass-passivated junction ensures stable avalanche performance and low incremental surge resistance under repetitive 10/1000 μs transients at 0.01% duty cycle.
The device is rated for 600 W peak pulse power per IEC 61000-4-5 and meets MSL Level 1 per J-STD-020 (reflow peak 260 °C). Its thermal resistance (RθJA = 100 °C/W) and 5.0 W steady-state power dissipation support operation up to +150 °C junction temperature when mounted on 0.2" × 0.2" copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 12.4–13.7 V at 1.0 mA - defines minimum clamping threshold under transient stress |
| Stand-off Voltage VWM | 11.1 V - maximum continuous reverse voltage before significant leakage begins |
| Clamping Voltage VC | ≤18.2 V at 33.0 A (10/1000 μs) - limits downstream IC voltage during surge events |
| Peak Pulse Power PPPM | 600 W - sustains high-energy transients without failure under standardized waveform |
| Max Reverse Leakage ID | ≤5.0 μA at VWM - ensures minimal standby power loss and signal integrity |
| Junction Temperature Range | −65 to +150 °C - supports operation in under-hood automotive and industrial environments |

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 | 400 W PPPM, same VWM/VBR range, SMA package (larger footprint, higher RθJA) | Limited to lower-energy transients; not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification and surge margin |
| SMCJ13CA | 1500 W PPPM, same VWM/VBR, SMC package (3.9 mm × 2.5 mm vs. SMB's 3.9 mm × 2.2 mm) | Higher surge capacity but larger PCB area and higher parasitic inductance | Choose for industrial systems requiring >1 kV surge immunity where board space allows |

FAQ
What does the "CA" suffix indicate in P6SMB13CAHE3_B/I?
The "CA" suffix denotes a bidirectional configuration: the P6SMB13CAHE3_B/I provides symmetrical clamping in both polarities, enabling protection of AC-coupled or floating signal paths without polarity orientation constraints. This differs from unidirectional "A" variants that require correct cathode/anode placement relative to system ground.
Is P6SMB13CAHE3_B/I suitable for automotive applications?
Yes, P6SMB13CAHE3_B/I is AEC-Q101 qualified and manufactured with HE3 suffix indicating RoHS-compliant and automotive-grade construction. It is explicitly rated for operation from −65 °C to +150 °C and validated for temperature cycling, humidity, and high-temperature operating life per automotive stress standards.
What is the maximum clamping voltage of P6SMB13CAHE3_B/I under surge conditions?
The P6SMB13CAHE3_B/I clamps to a maximum of 18.2 V when subjected to its rated 33.0 A peak pulse current (10/1000 μs waveform). This value is guaranteed across temperature and lifetime, ensuring downstream components see no more than 18.2 V during standardized surge events.
How does the SMB (DO-214AA) package of P6SMB13CAHE3_B/I compare to SMA or SMC packages?
The SMB package of P6SMB13CAHE3_B/I measures 3.94 mm × 2.18 mm × 2.29 mm-smaller than SMC (7.11 mm × 6.22 mm) and slightly smaller than SMA (4.57 mm × 2.92 mm). Its compact size enables dense layout in space-constrained modules, while maintaining 600 W surge capability and MSL Level 1 reflow compatibility.
Does P6SMB13CAHE3_B/I require a heatsink for normal operation?
No external heatsink is required for P6SMB13CAHE3_B/I under typical surge conditions. Its 5.0 W steady-state power dissipation and 100 °C/W junction-to-ambient thermal resistance are designed for operation with standard 0.2" × 0.2" copper pads per terminal. Continuous DC power must remain below 5.0 W at +50 °C ambient.
