Product details
Overview
SMB10J5.0HE3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, designed for high-energy surge protection on DC power rails and signal lines. It features a 5.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR) at 10 mA, 1000 W peak pulse power (10/1000 µs), 108.7 V clamping voltage at 108.7 A peak surge current, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMB10J5.0HE3/52 datasheet, SMB10J5.0HE3/52 pinout, SMB10J5.0HE3/52 application, or SMB10J5.0HE3/52 equivalent, key selection criteria include clamping performance under 10/1000 µs transients, unidirectional polarity for DC rail protection, RoHS-compliant AEC-Q101 qualification, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, triggering when reverse voltage exceeds its breakdown threshold to divert surge current away from downstream ICs or MOSFETs. Its glass-passivated junction ensures stable leakage (<1000 µA at VWM) and fast response time (<1 ns), while low incremental surge resistance enables effective energy absorption without thermal runaway.
The device is rated for -55 °C to +150 °C operating junction temperature, with thermal resistance of 72 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), supporting reliable operation in engine bay or industrial control environments where ambient temperatures exceed 85 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse working voltage before clamping begins; defines safe DC rail operating margin. |
| VBR (min/max) | 6.4 V / 7.07 V at 10 mA - Confirmed breakdown range ensures consistent turn-on across production lots. |
| VC @ IPPM | 9.2 V at 108.7 A - Clamping voltage during 10/1000 µs surge; determines maximum stress on protected circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0AHE3/52 | Same DO-214AA package, identical VWM/VBR/VC specs, but rated for 600 W PPPM (vs. 1000 W). | Lower surge rating limits use to consumer-grade or non-automotive industrial designs. | Select only if system-level surge testing confirms <600 W requirement and cost optimization is critical. |
| 1.5SMC5.0AHE3/A | DO-214AB (SMC) package, same electrical specs, higher thermal mass (RθJA = 40 °C/W), 1500 W PPPM rating. | Larger footprint (7.11 mm × 6.22 mm) requires PCB redesign; suited for high-power telecom or EV charging systems. | Choose when higher power handling and lower thermal resistance are needed, and board space permits larger package. |
Compared with SMBJ5.0AHE3/52 and 1.5SMC5.0AHE3/A, SMB10J5.0HE3/52 delivers optimal balance of 1000 W surge capability, AEC-Q101 qualification, and compact SMB footprint-making it the preferred choice for space-constrained automotive and industrial DC rail protection where both reliability and power density matter.

FAQ
What is the clamping voltage of SMB10J5.0HE3/52 at its rated peak pulse current?
The SMB10J5.0HE3/52 has a maximum clamping voltage (VC) of 9.2 V when subjected to its peak pulse current (IPPM) of 108.7 A under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees predictable overvoltage limiting for protected circuits. The SMB10J5.0HE3/52 maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C), making it suitable for under-hood automotive applications.
Is SMB10J5.0HE3/52 suitable for bidirectional signal line protection?
No, SMB10J5.0HE3/52 is a unidirectional TVS diode, intended for DC power rail or single-polarity signal protection. Its cathode-band marking and asymmetric IV curve mean it conducts only in reverse bias above VBR. For bidirectional protection (e.g., RS-485, USB D+/D−), a bi-directional variant such as SMB8J5.0CAHE3/52 must be used. The SMB10J5.0HE3/52 datasheet explicitly lists polarity as "uni-directional", and using it on AC-coupled or symmetrical lines would result in forward conduction and failure.
Does SMB10J5.0HE3/52 meet automotive qualification standards?
Yes, SMB10J5.0HE3/52 is AEC-Q101 qualified, as confirmed by Vishay's documentation (Document Number 88422, Revision 12-Nov-12). This qualification covers stress tests including high-temperature operating life (HTOL), temperature cycling (TCT), and human-body-model ESD (HBM ≥ 8 kV). The HE3 suffix denotes AEC-Q101 compliance and JESD 201 Class 2 whisker resistance-key requirements for automotive powertrain and chassis modules. The SMB10J5.0HE3/52 is not just "automotive grade" but fully tested and certified.
What is the thermal resistance of SMB10J5.0HE3/52, and how does it affect layout design?
The SMB10J5.0HE3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W and junction-to-lead (RθJL) of 20 °C/W, measured on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To achieve rated 1000 W pulse power, PCB layout must provide minimum pad area and thermal vias to ground planes. Reducing RθJA via enhanced copper pour directly improves repetitive surge endurance. The SMB10J5.0HE3/52 thermal data assumes JEDEC-standard mounting-deviations require derating per Figure 2 in the datasheet.
How does the HE3 suffix differ from E3 in SMB10J5.0HE3/52?
The HE3 suffix in SMB10J5.0HE3/52 indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas E3 denotes RoHS compliance only (commercial grade, no automotive qualification). Both share the same DO-214AA package and electrical specs, but HE3 adds rigorous stress testing for automotive use, including extended temperature cycling and lifetime reliability validation. For non-automotive applications where cost is prioritized, SMB10J5.0A-E3/52 may suffice-but SMB10J5.0HE3/52 is required for any AEC-Q101-mandated design.
