Product details
Overview
SMBG13HE3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the SMBG package, designed for robust overvoltage protection of sensitive electronics. It features a 13 V standoff voltage (VWM), 14.4–15.9 V breakdown voltage (VBR) at 1 mA, 21.5 V clamping voltage (VC) at 27.9 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 µs waveform - deployed in automotive power line and sensor interface protection.
For engineers reviewing the SMBG13HE3/52 datasheet, SMBG13HE3/52 pinout, SMBG13HE3/52 application, or SMBG13HE3/52 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, DO-215AA package dimensions, thermal resistance data, and real-world design implications for surge immunity in 12 V automotive systems.
Technical Context
The SMBG13HE3/52 operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology to achieve sub-nanosecond response to transients. Its clamping behavior is defined by a low incremental surge resistance and tightly specified VBR tolerance (±5 %), ensuring predictable turn-on during load dump or ISO 7637-2 pulse 5a events.
Designed for surface-mount placement on PCBs with 5.0 mm × 5.0 mm copper pads per terminal, it supports repetitive surge duty cycles up to 0.01 % and maintains stable operation across –55 °C to +150 °C junction temperature range. The HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse operating voltage before leakage exceeds 1.0 µA; sets upper limit for safe DC bias in 12 V automotive circuits. |
| VBR (min/max) | 14.4 V / 15.9 V at IT = 1 mA - Confirmed breakdown window ensures reliable conduction onset during transients without premature triggering. |
| VC @ IPPM | 21.5 V at 27.9 A - Clamped voltage under 10/1000 µs surge defines maximum stress imposed on downstream ICs or MOSFETs. |
| PPPM | 600 W - Peak pulse power rating determines survivability against standardized surges like ISO 7637-2 Pulse 1 (inductive switch-off) and Pulse 5a (load dump). |
| IFSM | 100 A - Non-repetitive forward surge rating (8.3 ms half-sine) validates robustness against high-energy battery connection transients. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance informs derating requirements when mounted on standard 5.0 mm × 5.0 mm copper pads. |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive-grade reliability including temperature cycling, HTRB, and ESD. |
Pinout & Package
Package: DO-215AA (SMBG), surface-mount gull-wing leaded case with cathode band marking; meets UL 94 V-0 flammability rating and RoHS compliance (HE3 suffix).

Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump transients (ISO 7637-2 Pulse 5a) and inductive switching spikes. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and ground, clamping surges within 1 ns to limit voltage seen by downstream regulators and microcontrollers. Use Value: Limits clamped voltage to 21.5 V at 27.9 A, preventing damage to 3.3 V or 5 V logic supplies downstream of DC/DC converters. |
Use Scenario: Shielding analog sensor outputs (e.g., pressure, temperature) in factory automation PLCs from ESD and cable-induced transients. IC Role / Device Role / Timing Role: TVS connected across differential signal pair or single-ended output to chassis ground, absorbing ±8 kV contact ESD per IEC 61000-4-2. Use Value: Sub-nanosecond response and <1.0 µA leakage at 13 V preserve signal integrity and offset accuracy in millivolt-level sensor signals. |
| Telecom Power Input Protection | Consumer Device USB Port Protection |
|
Use Scenario: Safeguarding AC/DC adapter inputs in base station power supplies against lightning-induced surges on primary-side rectifier outputs. IC Role / Device Role / Timing Role: Primary-side TVS placed after bridge rectifier and before bulk capacitor, absorbing line-to-line and line-to-ground transients. Use Value: 600 W rating and 100 A IFSM withstand repeated 10/1000 µs surges without degradation in telecom infrastructure deployments. |
Use Scenario: Adding secondary-level surge immunity to USB VBUS lines in portable monitors and docking stations. IC Role / Device Role / Timing Role: Unidirectional TVS between VBUS and ground, activated only during overvoltage events while remaining invisible to normal 5 V operation. Use Value: 13 V VWM allows clean 5 V pass-through with no loading; 21.5 V clamping prevents USB PHY IC latch-up during hot-plug transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A-E3/52 | Same VWM (13 V), identical DO-214AA (SMB) package but slightly higher VC (22.5 V @ 27.2 A); lower IPPM (27.2 A vs. 27.9 A). | Not AEC-Q101 qualified; rated for commercial/industrial use only. | Select SMBJ13A-E3/52 only for non-automotive designs where cost optimization outweighs qualification requirements. |
| SMCJ13AHE3/52 | Same VWM and AEC-Q101 qualification, but larger DO-214AB (SMC) package; higher PPPM (1500 W) and VC (24.4 V @ 61.5 A). | Better suited for higher-energy threats (e.g., ISO 16750-2 long-duration surges); requires more PCB area. | Choose SMCJ13AHE3/52 when system-level testing reveals insufficient margin with 600 W rating or when layout allows larger footprint. |
Compared with SMBJ13A-E3/52 and SMCJ13AHE3/52, the SMBG13HE3/52 uniquely balances AEC-Q101 compliance, 600 W surge handling, and compact DO-215AA footprint - making it optimal for space-constrained automotive modules needing certified reliability without over-engineering.

FAQ
What is the clamping voltage of SMBG13HE3/52 and how does it protect downstream components?
The SMBG13HE3/52 has a maximum clamping voltage (VC) of 21.5 V at 27.9 A peak pulse current (10/1000 µs). This value defines the highest voltage imposed on protected circuitry during a surge event. By limiting transient voltage to ≤21.5 V, the SMBG13HE3/52 prevents overvoltage stress on 3.3 V or 5 V ICs, MOSFET gate oxides, and regulator inputs - directly enabling compliance with ISO 7637-2 Pulse 1 and Pulse 5a immunity requirements in automotive designs using the SMBG13HE3/52.
Is SMBG13HE3/52 suitable for bi-directional transient protection?
No, SMBG13HE3/52 is a unidirectional TVS diode, indicated by the "A" suffix (not "CA"). It conducts only in reverse bias above VBR and blocks forward current beyond its 1.2 V forward voltage drop. For bi-directional protection - such as AC signal lines or differential buses - a part like SMBG13CAHE3/52 would be required. Using SMBG13HE3/52 in bi-directional configurations risks forward conduction failure or inadequate clamping during negative transients.
What does the "HE3" suffix mean in SMBG13HE3/52?
The "HE3" suffix in SMBG13HE3/52 denotes two key qualifications: "H" indicates AEC-Q101 qualification for automotive reliability, and "E3" signifies RoHS-compliant, matte tin-plated leads meeting JESD 201 Class 2 whisker resistance. This distinguishes it from commercial-grade "E3" variants (e.g., SMBG13A-E3/52) and confirms suitability for automotive applications where long-term solder joint integrity and stress-test validation are mandatory for the SMBG13HE3/52.
How does the DO-215AA (SMBG) package compare thermally to DO-214AA (SMB)?
The DO-215AA (SMBG) package used by SMBG13HE3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 5.0 mm × 5.0 mm copper pads - identical to the DO-214AA (SMB) package. However, DO-215AA features wider leads and improved gull-wing geometry, enhancing mechanical robustness and solder joint reliability under thermal cycling, which is critical for AEC-Q101 validation of the SMBG13HE3/52 in automotive environments.
Can SMBG13HE3/52 replace SMBJ13A in an existing design?
SMBG13HE3/52 is not a direct drop-in replacement for SMBJ13A due to package differences: SMBG uses DO-215AA, while SMBJ uses DO-214AA. Though both have identical VWM, VBR, and VC specs, the DO-215AA footprint requires PCB pad revision. Additionally, SMBG13HE3/52 adds AEC-Q101 qualification absent in SMBJ13A - so replacement is viable only if layout changes are acceptable and automotive qualification is needed for the SMBG13HE3/52.
