Product details
Overview
SMBG5.0HE3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-215AA (SMBG) package, designed for primary overvoltage protection of 5 V DC power rails and I/O lines. It delivers 600 W peak pulse power (10/1000 μs), clamps transients to ≤9.2 V at 65.2 A, and features 6.4–7.07 V breakdown voltage at 10 mA test current. Used in automotive ECUs and industrial sensor interfaces where AEC-Q101 qualification and low clamping voltage are critical.
For engineers reviewing the SMBG5.0HE3/52 datasheet, SMBG5.0HE3/52 pinout, SMBG5.0HE3/52 application, or SMBG5.0HE3/52 equivalent, key selection criteria include its 5.0 V stand-off voltage, 9.2 V max clamping at rated surge, AEC-Q101 qualification, RoHS-compliant HE3 whisker-tested terminations, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: under normal bias it presents <800 μA leakage at 5.0 V; during transient events exceeding 6.4 V, it avalanches rapidly (<1 ns response) to divert surge current away from downstream ICs. Its 100 °C/W junction-to-ambient thermal resistance requires careful PCB copper pad design per Vishay's 0.2" × 0.2" recommendation.
The device complies with ANSI/IEEE C62.35 for surge suppression and meets UL 497B recognition (QVGQ2). Its 150 °C maximum junction temperature and 100 A 8.3 ms forward surge rating support robust operation in automotive load-dump scenarios, while the matte tin-plated leads ensure solderability per J-STD-002 and JESD 22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VWM) | 5.0 V - Maximum continuous reverse voltage before significant leakage; sets operating margin for 5 V rail protection |
| Breakdown Voltage (VBR) | 6.4–7.07 V at 10 mA - Confirmed avalanche initiation range; ensures reliable turn-on before system damage |
| Clamping Voltage (VC) | 9.2 V at 65.2 A (10/1000 μs) - Actual voltage seen by protected circuit during full-rated surge |
| Peak Pulse Power (PPPM) | 600 W - Sustained energy-handling capability for standard lightning/surge waveforms |
| Leakage Current (ID) | <800 μA at 5.0 V - Minimal standby power loss and signal integrity impact on 5 V logic lines |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0AHE3/52 | Same DO-215AA package, identical VWM/VBR/VC, but lower 300 W PPPM rating | Not suitable for ISO 7637-2 Pulse 5a (load dump); limited to lower-energy transients | Select SMBG5.0HE3/52 when 600 W surge handling is required for automotive or industrial mains-coupled surges |
| 1.5SMC5.0AHE3/A | DO-214AB (SMC) package, same electrical specs, higher thermal mass but larger footprint (7.11 mm × 6.22 mm) | Requires PCB redesign due to 3.5× larger body size and different pad layout | Choose SMBG5.0HE3/52 for space-constrained designs needing AEC-Q101 compliance in compact SMBG outline |
Compared with SMBJ5.0AHE3/52 and 1.5SMC5.0AHE3/A, SMBG5.0HE3/52 uniquely combines 600 W surge rating, AEC-Q101 qualification, and DO-215AA footprint-enabling drop-in replacement in automotive modules where both power density and qualification are mandatory.

FAQ
What is the maximum clamping voltage of SMBG5.0HE3/52 under rated surge conditions?
The SMBG5.0HE3/52 exhibits a maximum clamping voltage (VC) of 9.2 V when subjected to its rated 65.2 A peak pulse current (10/1000 μs waveform). This value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's datasheet revision 12-Nov-12, page 2. The low clamping ensures protected 5 V ICs remain within absolute maximum ratings during surge events.
Is SMBG5.0HE3/52 suitable for bi-directional transient protection?
No, SMBG5.0HE3/52 is a unidirectional TVS diode, indicated by the "A" suffix (not "CA"). Its cathode band marking and electrical characteristics-including forward surge rating (IFSM = 100 A)-are defined only for reverse-biased avalanche operation. For bi-directional protection at 5 V, the SMBG5.0CA variant must be used instead.
Does SMBG5.0HE3/52 meet automotive qualification standards?
Yes, SMBG5.0HE3/52 is explicitly AEC-Q101 qualified, as stated in the Vishay datasheet (page 1, "MECHANICAL DATA" section) and confirmed by the "HE3" suffix denoting JESD 201 Class 2 whisker testing and automotive-grade screening. This qualification covers temperature cycling, high-temperature reverse bias, and ESD robustness.
What is the thermal resistance of SMBG5.0HE3/52, and how does it affect PCB layout?
The SMBG5.0HE3/52 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 terminal. To maintain safe junction temperatures under repeated surges, PCB layout must replicate this pad area-reducing RθJA improves power dissipation and prevents thermal runaway during duty-cycle surges.
How does the "HE3" suffix differ from "E3" in SMBG5.0HE3/52?
The "HE3" suffix indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance (vs. Class 1A for "E3"). Per Vishay documentation, HE3 devices undergo additional automotive stress screening and higher-temperature storage testing, making SMBG5.0HE3/52 appropriate for under-hood and safety-critical applications where E3-grade parts are insufficient.
