Product details
Overview
P6SMB13AHE3_B/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 13 V breakdown voltage (VBR = 12.4–13.7 V at 1 mA), 11.1 V stand-off voltage (VWM), and 18.2 V maximum clamping voltage (VC) at 33.0 A peak pulse current (IPPM). It delivers 600 W peak pulse power with 10/1000 μs waveform and is AEC-Q101 qualified for automotive applications.
For engineers reviewing the P6SMB13AHE3_B/H datasheet, P6SMB13AHE3_B/H pinout, P6SMB13AHE3_B/H application, or P6SMB13AHE3_B/H equivalent, this device serves as a robust overvoltage protection solution for DC power rails and signal lines in automotive ECUs, industrial sensors, and telecom interfaces where fast response (<1 ns), low clamping ratio (VC/VBR ≈ 1.4), and high surge reliability are required.
Technical Context
This TVS diode operates as a unidirectional clamping device: reverse-biased during normal operation (blocking up to 11.1 V), then avalanche-conducting within nanoseconds when transient voltage exceeds VBR. Its glass-passivated junction ensures stable leakage (<5 μA at VWM) and long-term reliability under repetitive surges.
Designed for PCB-level protection of downstream ICs and MOSFETs, it complies with IEC 61000-4-2 (ESD) and IEC 61000-4-4 (EFT) immunity requirements when mounted per recommended 0.2" × 0.2" copper pads. Thermal resistance RθJA = 100 °C/W enables operation up to +150 °C junction temperature without forced cooling.
Key Specifications

|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at 1.0 mA - defines precise avalanche onset threshold for repeatable clamping behavior |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A-E3/52 | Same VBR range (12.4–13.7 V), but SMA package (DO-214AC); lower PPPM = 400 W | Lower surge margin; suitable only for non-automotive consumer applications with reduced threat levels | Select when board space permits larger SMA footprint and automotive qualification is not required. |
| 1.5SMC13A | Same electrical specs, but SMC (DO-214AB) package; higher thermal mass, RθJA = 65 °C/W | Better thermal performance but 30% larger footprint; not AEC-Q101 qualified | Choose for industrial power supplies needing enhanced thermal dissipation without automotive compliance. |

FAQ
What is the clamping voltage of P6SMB13AHE3_B/H at its rated peak pulse current?
The P6SMB13AHE3_B/H has a maximum clamping voltage (VC) of 18.2 V at 33.0 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured under standardized test conditions and represents the upper voltage limit imposed on protected circuitry during worst-case transient events. The P6SMB13AHE3_B/H maintains this clamping performance across its full operating temperature range.
Is P6SMB13AHE3_B/H suitable for automotive applications?
Yes, P6SMB13AHE3_B/H is AEC-Q101 qualified and specifically designed for automotive use. Its suffix "HE3_B/H" denotes RoHS-compliant construction with AEC-Q101 qualification, validated for temperature cycling, highly accelerated life testing, and ESD robustness. The P6SMB13AHE3_B/H is commonly deployed in engine control units, body electronics, and ADAS sensor modules where reliability under harsh environmental conditions is mandatory.
How does the P6SMB13AHE3_B/H differ from bidirectional variants like P6SMB13CA?
The P6SMB13AHE3_B/H is unidirectional, meaning it conducts only in reverse bias above VBR and blocks forward current like a standard diode. In contrast, P6SMB13CA is bidirectional and symmetrical-clamping transients of either polarity. The P6SMB13AHE3_B/H features a cathode band marking and is used on DC rails where polarity is fixed; P6SMB13CA is reserved for AC-coupled or floating signal lines such as RS-485 or antenna feeds.
What is the maximum operating junction temperature for P6SMB13AHE3_B/H?
The P6SMB13AHE3_B/H has a maximum junction temperature (TJ) rating of +150 °C, verified per JEDEC standards. This allows uninterrupted operation in under-hood automotive environments and high-ambient industrial enclosures. Derating curves in the datasheet confirm usable power dissipation down to 50% at 125 °C ambient when mounted on 0.2" × 0.2" copper pads-critical for thermal design validation of the P6SMB13AHE3_B/H.
Does P6SMB13AHE3_B/H require special PCB layout considerations?
Yes, effective transient suppression with P6SMB13AHE3_B/H requires adherence to Vishay's recommended pad layout: 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to ensure specified thermal and surge performance. Short, low-inductance traces between the P6SMB13AHE3_B/H and protected node are essential-long traces increase clamping voltage due to parasitic inductance. The P6SMB13AHE3_B/H must be placed as close as possible to the connector or entry point of the transient.
