Product details
Overview
SMBG13AHE3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for robust overvoltage protection of sensitive electronics. It features a 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 µs), 27.9 A peak pulse current (IPPM), and clamps to ≤21.5 V at rated surge - deployed on automotive sensor signal lines, industrial I/O ports, and DC power rails.
For engineers reviewing the SMBG13AHE3/52 datasheet, SMBG13AHE3/52 pinout, SMBG13AHE3/52 application, or SMBG13AHE3/52 equivalent, key selection criteria include its AEC-Q101 qualification, 150 °C max junction temperature, low 1.0 µA reverse leakage at VWM, RoHS-compliant matte tin terminations, and compatibility with automated SMT placement on standard 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, responding to fast transients (sub-nanosecond response) by entering avalanche conduction before downstream components are stressed. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and long-term reliability under repetitive surge conditions.
Rated for 600 W peak pulse power per 10/1000 µs waveform at 0.01 % duty cycle, it delivers 27.9 A IPPM with ≤21.5 V clamping voltage - enabling effective protection of 12 V automotive systems and 15 V industrial logic interfaces without excessive voltage overshoot.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - maximum continuous reverse operating voltage before significant leakage; sets upper limit for normal circuit operation. |
| VBR (min/max) | 14.4 V / 15.9 V at 1 mA - guaranteed avalanche onset range; ensures predictable turn-on during transients. |
| IPPM | 27.9 A - peak surge current it safely shunts at 10/1000 µs waveform; defines protection margin against ISO 7637-2 Pulse 1/2a. |
| VC | ≤21.5 V at IPPM - maximum clamped voltage seen by protected IC; must stay below downstream component absolute max rating. |
| ID @ VWM | ≤1.0 µA - ultra-low reverse leakage; avoids loading low-power sensor outputs or battery-backed circuits. |
| TJ max | +150 °C - enables use in under-hood automotive environments and high-ambient industrial enclosures. |
| Package | SMBG (DO-215AA) - surface-mount, low-profile (1.96 mm height), MSL Level 1, compatible with reflow profiles up to 260 °C peak. |
Pinout & Package
SMBG13AHE3/52 uses the SMBG (DO-215AA) package: a two-terminal, gull-wing SMD outline with cathode band marking. Terminals are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A-E3/52 | Same VWM/VBR/VC, but SMB (DO-214AA) package - 2.79 mm height vs. SMBG's 1.96 mm; RθJA = 110 °C/W vs. 100 °C/W. | Less suitable for ultra-low-profile automotive modules; identical electrical performance for most board-level designs. | Select SMBG13AHE3/52 when board height < 2.0 mm is required or AEC-Q101 qualification is mandatory. |
| 1.5SMC13A | Same electrical specs, but larger SMC (DO-214AB) package - 2.62 mm height, higher thermal mass; not AEC-Q101 qualified. | Preferred for non-automotive industrial use where space and qualification are less constrained. | Choose SMBG13AHE3/52 for automotive Tier-1 supply chains or where MSL Level 1 and 260 °C reflow are required. |

FAQ
What is the breakdown voltage range of SMBG13AHE3/52?
The SMBG13AHE3/52 has a guaranteed breakdown voltage (VBR) range of 14.4 V to 15.9 V at 1 mA test current, per Vishay's datasheet revision 09-Jan-2024. This tight ±5 % tolerance ensures consistent clamping behavior across production lots and temperature extremes, critical for protecting 12 V automotive electronics where overvoltage margins are narrow.
Is SMBG13AHE3/52 suitable for automotive applications?
Yes, SMBG13AHE3/52 is AEC-Q101 qualified and explicitly rated for automotive use - validated for temperature cycling, high-temperature reverse bias, and surge endurance. Its HE3 suffix denotes RoHS compliance and AEC-Q101 qualification, making SMBG13AHE3/52 appropriate for engine control units, ADAS camera modules, and body electronics exposed to harsh thermal and electrical environments.
What is the maximum clamping voltage of SMBG13AHE3/52 at rated surge current?
The SMBG13AHE3/52 clamps to a maximum of 21.5 V at its rated peak pulse current (IPPM) of 27.9 A under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and guarantees that protected downstream ICs - such as CAN transceivers or microcontrollers with 24 V absolute maximum ratings - remain within safe operating limits during transient events.
Does SMBG13AHE3/52 have polarity marking, and how is it oriented on PCB?
Yes, SMBG13AHE3/52 is unidirectional and features a cathode band marking on the package body. During PCB layout, the banded end must connect to the line being protected (e.g., signal or power rail), while the anode connects to ground. Reversing polarity renders the device ineffective for surge suppression and may cause catastrophic failure under reverse bias.
What packaging and reel configuration is supplied for SMBG13AHE3/52?
SMBG13AHE3/52 is supplied in 7" diameter plastic tape and reel format, with 750 units per reel (package code /52).
