Product details
Overview
SMBJ10-E3/52 from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 17.0 V maximum clamping voltage (VC) at 35.3 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed on IC power rails, MOSFET gate drivers, and sensor signal lines in industrial and telecom equipment.
For engineers reviewing the SMBJ10-E3/52 datasheet, SMBJ10-E3/52 pinout, SMBJ10-E3/52 application, or SMBJ10-E3/52 equivalent, key selection criteria include clamping performance under 35.3 A surge, thermal resistance (RθJA = 100 °C/W), unidirectional polarity with cathode band marking, and RoHS-compliant commercial-grade qualification per J-STD-020 MSL level 1.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR (11.1–12.3 V), it avalanches to limit transient energy across protected circuit nodes. Its low incremental surge resistance ensures minimal voltage overshoot during fast transients, while glass-passivated junction enables stable long-term reliability under repetitive surge stress.
Designed for PCB-level ESD and surge immunity per IEC 61000-4-2/4-4/4-5, SMBJ10-E3/52 delivers sub-nanosecond response time and supports automated SMT placement. It is rated for TJ = –55 °C to +150 °C operation and meets UL 497B recognition (QVGQ2) for telecom and industrial protectors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before leakage exceeds 5 µA; defines safe DC bias margin for protected line. |
| VBR (min/max) | 11.1 V / 12.3 V at IT = 1 mA - Ensures reliable avalanche initiation within tight tolerance for predictable clamping onset. |
| VC @ IPPM | 17.0 V at 35.3 A - Clamped voltage during 10/1000 µs surge; must remain below downstream IC absolute maximum rating. |
| PPPM | 600 W - Peak transient power handling capability; validates protection against Level 4 IEC 61000-4-5 (4 kV/2 Ω) surges. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; determines derating above 25 °C ambient. |
| IFSM | 100 A - Non-repetitive forward surge rating (8.3 ms half-sine); supports accidental reverse-bias fault recovery in power supply inputs. |
| Package | SMB (DO-214AA) - Surface-mount outline with 5.59 mm max length, 4.06 mm max width, and 2.20 mm max height; compatible with standard SMT reflow profiles. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A-E3/52 | Same electrical specs and package; identical marking code "AX" and VBR range (11.1–12.3 V); differs only in ordering suffix convention (no hyphen in base P/N). | No functional difference; used interchangeably in BOMs where Vishay internal part numbering preference applies. | Select SMBJ10A-E3/52 if sourcing from distributors listing base P/N without hyphen; electrically and mechanically identical to SMBJ10-E3/52. |
| P6SMB10A | Same SMB package and 10 V VWM, but lower PPPM (600 W same), higher VC (18.0 V at 33.3 A), and wider VBR tolerance (11.1–13.4 V); not AEC-Q101 qualified. | Less precise clamping margin; suitable for cost-sensitive consumer applications where tighter VC is non-critical. | Choose P6SMB10A only when clamping voltage margin > 17.0 V is acceptable and automotive qualification is unnecessary. |
Compared with SMBJ10A-E3/52 (identical function) and P6SMB10A (looser VBR/VC specs), SMBJ10-E3/52 offers guaranteed 17.0 V clamping and commercial-grade RoHS compliance with documented MSL level 1 handling - making it optimal for industrial and telecom designs requiring consistent surge margin and process reliability.

FAQ
What is the maximum clamping voltage of SMBJ10-E3/52 and under what test condition?
The SMBJ10-E3/52 has a maximum clamping voltage (VC) of 17.0 V, measured at a peak pulse current (IPPM) of 35.3 A using a 10/1000 µs waveform. This value is specified in the Vishay datasheet (Document Number: 88392, Rev. 09-Jan-2024) and represents the upper voltage limit imposed on protected circuitry during worst-case surge events - critical for ensuring downstream ICs remain within their absolute maximum ratings.
Is SMBJ10-E3/52 suitable for automotive applications?
SMBJ10-E3/52 is a commercial-grade RoHS-compliant part (E3 suffix) and is not AEC-Q101 qualified. For automotive use, Vishay offers the SMBJ10HE3 variant (with HE3 suffix), which carries AEC-Q101 qualification and extended temperature validation. The SMBJ10-E3/52 remains appropriate for industrial, telecom, and consumer applications where automotive-grade reliability is not mandated.
What does the "-E3/52" suffix indicate in SMBJ10-E3/52?
The "-E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 and JESD 22-B102 whisker testing. The "/52" indicates packaging in 7" diameter plastic tape and reel, with a base quantity of 750 units per reel - a standard logistics format for SMT production lines requiring automated pick-and-place feeders.
How does SMBJ10-E3/52 differ from bidirectional variants like SMBJ10CA?
SMBJ10-E3/52 is unidirectional, with polarity marked by a cathode band and intended for DC-biased lines (e.g., power rails). In contrast, SMBJ10CA is bidirectional, lacks polarity marking, and provides symmetrical clamping for AC or floating signal lines. Their VWM (10 V), VBR (11.1–12.3 V), and VC (17.0 V) match, but SMBJ10-E3/52 cannot replace SMBJ10CA in AC-coupled applications without circuit redesign.
What is the thermal resistance and maximum junction temperature of SMBJ10-E3/52?
SMBJ10-E3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads, and a maximum operating junction temperature (TJ) of +150 °C. These values define its power derating curve above 25 °C ambient and confirm suitability for enclosed industrial enclosures with limited airflow - essential for sustained surge duty cycle planning.
