Product details
Overview
SMBG5.0CHE3/52 from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-215AA (SMBG) package, designed for clamping inductive switching transients and ESD events on signal/power lines. It features 5.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR), 600 W peak pulse power (10/1000 µs), <800 µA reverse leakage at VWM, and 9.2 V clamping voltage (VC) at 65.2 A IPPM - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMBG5.0CHE3/52 datasheet, SMBG5.0CHE3/52 pinout, SMBG5.0CHE3/52 application, or SMBG5.0CHE3/52 equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, MSL Level 1 moisture sensitivity, 150 °C max junction temperature, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a voltage-clamped surge protector in bi-directional configuration, with symmetrical avalanche breakdown behavior in both polarities. Its glass-passivated junction ensures stable VBR tolerance (±5% typical), low incremental surge resistance, and fast response time (<1 ns), enabling effective suppression of ESD (IEC 61000-4-2) and lightning-induced surges (IEC 61000-4-5).
The SMBG5.0CHE3/52 is rated for 600 W peak pulse power under 10/1000 µs waveform at TA = 25 °C, derated linearly above 25 °C per Fig. 2, and supports repetitive surge duty cycle ≤0.01%. Thermal resistance is RθJA = 100 °C/W (on 5.0 mm × 5.0 mm pads) and RθJL = 20 °C/W, supporting reliable operation up to TJ = 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - maximum continuous reverse working voltage before clamping begins; defines safe operating margin for 5 V logic/sensor rails |
| VBR (min/max) | 6.4 V / 7.07 V at IT = 10 mA - guaranteed avalanche onset range; ensures predictable turn-on during overvoltage events |
| VC @ IPPM | 9.2 V at 65.2 A - clamped voltage during 600 W surge; limits downstream IC stress below 10 V threshold |
| PPPM | 600 W (10/1000 µs) - peak transient energy handling capacity; sufficient for ISO 7637-2 Pulse 1/2a/3a and IEC 61000-4-5 Level 3 |
| ID @ VWM | <800 µA - ultra-low leakage at rated stand-off; avoids signal integrity degradation in high-impedance sensor lines |
| TJ max | +150 °C - extended thermal rating enabling use in under-hood automotive environments and industrial enclosures |
| Qualification | AEC-Q101 qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0CA-E3/52 | Same DO-214AA (SMB) package, identical VWM/VBR/VC specs, but not AEC-Q101 qualified; RθJA = 110 °C/W | Approved for commercial/industrial use only; unsuitable for automotive under-hood deployment | Select when AEC-Q101 is not required and cost optimization is prioritized over automotive qualification |
| SMCJ5.0AHE3/52 | DO-214AB (SMC) package, higher 1500 W PPPM, same VWM/VBR, but unidirectional; requires polarity-aware layout | Used where higher surge margin is needed (e.g., power supply inputs), but adds design complexity due to polarity marking and larger footprint | Select when system-level surge testing exceeds 600 W or when unidirectional protection suffices with explicit ground referencing |
Compared with SMBJ5.0CA-E3/52 and SMCJ5.0AHE3/52, the SMBG5.0CHE3/52 uniquely combines AEC-Q101 qualification, bi-directional symmetry, and SMBG package size - making it optimal for space-constrained, automotive-grade signal line protection where polarity-agnostic mounting and extended temperature reliability are mandatory.

FAQ
What is the clamping voltage of SMBG5.0CHE3/52 and how is it measured?
The SMBG5.0CHE3/52 has a maximum clamping voltage (VC) of 9.2 V at 65.2 A peak pulse current (IPPM), tested using a 10/1000 µs waveform per IEC 61000-4-5. This value is guaranteed across temperature and represents the upper limit of voltage imposed on protected circuitry during a 600 W transient event - directly verified in Vishay's characterization lab per Document Number 88456.
Is SMBG5.0CHE3/52 suitable for automotive applications?
Yes, SMBG5.0CHE3/52 is AEC-Q101 qualified and rated for operation from –55 °C to +150 °C, making it suitable for under-hood and cabin-mounted automotive electronics. Its bi-directional architecture, low leakage, and robust surge handling align with requirements for CAN, LIN, and sensor interface protection in modern ECU designs.
What does the "HE3" suffix indicate in SMBG5.0CHE3/52?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes this grade from commercial "E3" variants (e.g., SMBG5.0A-E3/52), confirming enhanced reliability testing for automotive and industrial use cases.
How does SMBG5.0CHE3/52 differ from unidirectional TVS diodes like SMBG5.0A?
Unlike unidirectional SMBG5.0A, the SMBG5.0CHE3/52 is bi-directional with symmetrical breakdown in both polarities and no cathode marking. This eliminates orientation dependency during placement and enables protection of AC-coupled or differential signal lines - critical for USB, RS-485, and sensor bridge outputs.
What PCB pad layout is recommended for SMBG5.0CHE3/52 to achieve rated thermal performance?
Vishay specifies a minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad per terminal to achieve the rated RθJA = 100 °C/W and full 600 W PPPM capability. Smaller pads increase thermal resistance and reduce surge current handling - verified in Fig. 2 derating curves of Document 88456.
