Product details
Overview
P6SMB13AHE3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 13 V breakdown voltage (VBR = 12.4–13.7 V at 1 mA), 11.1 V stand-off voltage (VWM), 18.2 V maximum clamping voltage (VC) at 33 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 power rails.
For engineers reviewing the P6SMB13AHE3/5B datasheet, P6SMB13AHE3/5B pinout, P6SMB13AHE3/5B application, or P6SMB13AHE3/5B equivalent, this part delivers AEC-Q101 qualification, low incremental surge resistance, fast response time, and RoHS-compliant matte tin-plated leads suitable for automated SMT assembly and high-reliability board-level ESD/surge protection.
Technical Context
The P6SMB13AHE3/5B operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<5 µA at VWM), while thermal resistance (RθJA = 100 °C/W) supports operation up to 150 °C junction temperature under defined PCB pad layout (0.2" × 0.2" copper).
It complies with IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and ISO 7637-2 (automotive surge) immunity requirements when applied with proper trace routing and grounding. The device is rated for repetitive 0.01% duty cycle pulses and meets J-STD-020 MSL level 1 (260 °C peak reflow).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 12.4–13.7 V at 1 mA test current - defines precise conduction onset for reliable overvoltage triggering |
| Stand-off Voltage VWM | 11.1 V - maximum continuous reverse voltage before leakage exceeds 5 µA, ensuring no false triggering in normal operation |
| Clamping Voltage VC | 18.2 V at 33 A IPPM - limits transient voltage seen by protected downstream circuitry during 10/1000 µs surge |
| Peak Pulse Power PPPM | 600 W - sustains single 10/1000 µs surges without degradation when mounted per recommended 5.0 mm × 5.0 mm copper pads |
| Operating Temperature | -65 °C to +150 °C - enables use in under-hood automotive, industrial motor drives, and outdoor power supplies |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness per stress test plan |
| Package | SMB (DO-214AA) - low-profile surface-mount outline with cathode band marking, compatible with standard SMT pick-and-place |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case meeting UL 94 V-0 flammability rating; matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; polarity indicated by cathode band on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

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-E3/5B | Same SMB package, identical VWM/VBR/VC specs, but not AEC-Q101 qualified; RθJA = 110 °C/W vs. 100 °C/W | Targeted at commercial/industrial use only; unsuitable for automotive under-hood deployment | Select when AEC-Q101 compliance is not required and cost sensitivity outweighs automotive qualification needs |
| 1.5SMC13A | Higher-power SMC package (1500 W PPPM), same electrical specs, larger footprint (7.11 × 6.22 mm vs. 4.57 × 3.94 mm) | Used where higher surge margin is needed and PCB space allows larger package; not drop-in compatible | Choose for harsher environments (e.g., railway, heavy machinery) requiring >600 W surge handling without redesigning layout |
Compared with SMAJ13A-E3/5B and 1.5SMC13A, the P6SMB13AHE3/5B uniquely combines AEC-Q101 qualification, SMB footprint efficiency, and 100 °C/W thermal resistance - making it optimal for space-constrained automotive ECUs needing certified reliability without sacrificing surge margin.

FAQ
What is the clamping voltage of the P6SMB13AHE3/5B at its rated peak pulse current?
The P6SMB13AHE3/5B has a maximum clamping voltage (VC) of 18.2 V at 33 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value is measured with the device mounted on 0.2" × 0.2" copper pads per JEDEC standards and represents the upper voltage limit imposed on protected circuitry during a full-rated surge event. The P6SMB13AHE3/5B maintains this clamping performance across its operating temperature range.
Is the P6SMB13AHE3/5B suitable for automotive applications?
Yes, the P6SMB13AHE3/5B is AEC-Q101 qualified, as confirmed by the "HE3" suffix and Vishay documentation. It undergoes stress testing for temperature cycling, high-temperature reverse bias, and ESD robustness required for automotive electronics. The P6SMB13AHE3/5B is commonly deployed in engine control units, body control modules, and ADAS sensor power rails where ISO 7637-2 compliance and long-term reliability are mandatory.
What does the "5B" in P6SMB13AHE3/5B indicate?
The "5B" suffix denotes the packaging configuration: 13-inch diameter plastic tape and reel containing 3200 units. This format is optimized for high-volume SMT assembly lines using standard 13" feeder systems. The "HE3" portion confirms RoHS-compliant construction and AEC-Q101 qualification, while "P6SMB13A" specifies the 13 V unidirectional TVS variant in the P6SMB family. The P6SMB13AHE3/5B is not compatible with 7" reel equipment without adapter hardware.
How does the P6SMB13AHE3/5B compare to bidirectional TVS diodes like P6SMB13CA?
The P6SMB13AHE3/5B is unidirectional and conducts only during reverse-biased overvoltage events, making it ideal for DC power rail protection where polarity is fixed. In contrast, P6SMB13CA is bidirectional and clamps both positive and negative transients - suited for AC lines or differential signal pairs. The P6SMB13AHE3/5B offers lower leakage (<5 µA at VWM) than its bidirectional counterpart and is AEC-Q101 qualified, whereas P6SMB13CA variants may lack that certification depending on suffix.
What is the thermal resistance of the P6SMB13AHE3/5B, and how does it affect layout design?
The P6SMB13AHE3/5B 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 per JEDEC 51-3. This value assumes minimal copper area; increasing pad size or adding internal ground planes reduces RθJA. For reliable operation at 150 °C maximum junction temperature, designers must ensure ambient temperature plus power dissipation (≤5.0 W steady-state) stays within thermal limits. The P6SMB13AHE3/5B's thermal performance directly impacts surge repetition rate capability.
