Product details
Overview
P6SMB13CAHE3_B/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 and 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), 18.2 V maximum clamping voltage (VC) at 33.0 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6SMB13CAHE3_B/H datasheet, P6SMB13CAHE3_B/H pinout, P6SMB13CAHE3_B/H application, or P6SMB13CAHE3_B/H equivalent, this AEC-Q101 qualified TVS offers verified bidirectional surge suppression, SMB (DO-214AA) package compatibility, low incremental surge resistance, and stable clamping performance across -65 °C to +150 °C junction temperature range.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical electrical characteristics forward and reverse - enabling protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction ensures stable breakdown behavior and fast response time (<1 ns), while the low Rsurge supports effective energy diversion during ESD and lightning-induced surges.
The device is rated for 600 W peak pulse power under 10/1000 µs waveform at 0.01% duty cycle, derated linearly above 25 °C ambient per Fig. 2, and exhibits a typical thermal resistance of 100 °C/W (junction-to-ambient) on standard 0.2" × 0.2" copper pads - confirming suitability for compact PCB layouts with moderate thermal management.

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 SMB package, 13 V bidirectional rating, but lower 400 W PPPM (vs. 600 W) | Limited to lower-energy transients; not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification or higher surge margin |
| 1.5KE13CA | Through-hole DO-201 package, same 13 V rating and 600 W rating, higher thermal mass | Requires manual or wave soldering; unsuitable for high-density SMT designs | Choose for legacy through-hole boards or where board-level mechanical robustness is prioritized over footprint size |
Compared with SMAJ13CA and 1.5KE13CA, the P6SMB13CAHE3_B/H delivers AEC-Q101 qualification, superior SMT process compatibility, and identical 600 W surge capability in a smaller SMB footprint - making it optimal for new automotive and space-constrained industrial designs requiring production-grade reliability.

FAQ
What does the "CA" suffix indicate in P6SMB13CAHE3_B/H?
The "CA" suffix denotes a bidirectional configuration - meaning the P6SMB13CAHE3_B/H provides symmetrical transient suppression in both polarities, with identical breakdown and clamping characteristics regardless of voltage polarity applied. This eliminates polarity marking requirements and simplifies placement on AC or differential signal lines, unlike unidirectional variants (e.g., P6SMB13A) that require cathode alignment.
Is P6SMB13CAHE3_B/H RoHS-compliant and halogen-free?
Yes, P6SMB13CAHE3_B/H is RoHS-compliant per EU Directive 2011/65/EU and meets Vishay's halogen-free definition (total Cl + Br < 900 ppm, antimony < 900 ppm). The "HE3" suffix confirms RoHS compliance and AEC-Q101 qualification, while the "_B/H" denotes AEC-Q101 grade and 7" tape-and-reel packaging (750 units per reel).
How does the clamping voltage of P6SMB13CAHE3_B/H compare to its breakdown voltage?
The P6SMB13CAHE3_B/H has a minimum breakdown voltage (VBR) of 12.4 V and a maximum clamping voltage (VC) of 18.2 V at 33.0 A peak pulse current. This 5.8 V difference represents the dynamic voltage rise under surge conditions - a key design parameter ensuring downstream 12 V or 15 V logic remains within safe operating limits during transient events.
Can P6SMB13CAHE3_B/H replace P6SMB13A in an existing design?
No - P6SMB13CAHE3_B/H is bidirectional while P6SMB13A is unidirectional. Substituting them requires verifying circuit topology: P6SMB13A relies on polarity-aware placement (cathode marked), whereas P6SMB13CAHE3_B/H has no polarity marking and conducts identically in both directions. Layout changes may be needed if the original design depends on unidirectional blocking behavior.
What is the maximum operating temperature for P6SMB13CAHE3_B/H?
The P6SMB13CAHE3_B/H has a specified junction temperature range of -65 °C to +150 °C. Its maximum continuous operating temperature is therefore +150 °C, supported by thermal resistance values of RθJA = 100 °C/W (junction-to-ambient, on standard 0.2" × 0.2" copper pads) and RθJL = 20 °C/W (junction-to-lead), enabling reliable use in under-hood automotive and high-ambient industrial environments.
