Product details
Overview
SMB10J11-E3/5B from Vishay General Semiconductor is a unidirectional TransZorb® transient voltage suppressor diode in DO-214AA (SMB) package, designed for high-energy surge protection on power and signal lines. It features 11 V standoff voltage (VWM), 12.2–13.5 V breakdown voltage (VBR) at 1 mA, 18.2 V clamping voltage (VC) at 54.9 A peak pulse current, and 1000 W peak pulse power rating with 10/1000 µs waveform.
For engineers reviewing the SMB10J11-E3/5B datasheet, SMB10J11-E3/5B pinout, SMB10J11-E3/5B application, or SMB10J11-E3/5B equivalent, key selection criteria include clamping performance under 1000 W surges, AEC-Q101 qualification for automotive use, RoHS-compliant matte tin plating, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector, activating when reverse voltage exceeds its breakdown threshold to divert transient energy away from sensitive downstream circuitry. Its glass-passivated junction ensures stable leakage and long-term reliability under repetitive surge stress.
Designed per ANSI/IEEE C62.35 standards, SMB10J11-E3/5B delivers fast response time (<1 ns), low incremental surge resistance, and thermal stability up to 150 °C junction temperature. It meets MSL Level 1 per J-STD-020 and passes JESD 201 Class 1A whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 11 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin for 12 V nominal systems. |
| VBR (min/max) | 12.2 V / 13.5 V at 1 mA - Confirmed breakdown range ensures reliable turn-on without premature conduction during normal operation. |
| VC @ IPPM | 18.2 V at 54.9 A - Clamping voltage under full 1000 W surge; limits protected IC voltage to safe levels during transients. |
| PPPM | 1000 W (10/1000 µs) - Peak surge power handling capacity; supports robust protection against IEC 61000-4-5 Level 4 surges. |
| ID @ VWM | 5.0 µA max - Low reverse leakage preserves system efficiency and prevents false triggering in low-power circuits. |
| TJ max | 150 °C - Enables operation in under-hood automotive environments and industrial enclosures without derating. |
| RθJA | 72 °C/W - Thermal resistance informs PCB pad design; requires ≥0.2" × 0.2" copper pads per terminal for rated power dissipation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11A-E3/5B | Same DO-214AA package, identical VWM (11 V), VBR (12.2–13.5 V), VC (18.2 V), and PPPM (1000 W); differs only in part numbering convention (SMBJ vs. SMB10J). | No functional difference; both meet AEC-Q101 and RoHS requirements; interchangeable in all designs. | Select SMBJ11A-E3/5B if sourcing from distributors listing SMBJ-series inventory; electrically and mechanically identical to SMB10J11-E3/5B. |
| 1.5SMC11A | Higher package thermal resistance (RθJA ≈ 110 °C/W), larger DO-214AB (SMC) footprint (7.11 mm × 6.22 mm), same electrical specs but lower power density. | Requires larger PCB area and more copper for equivalent thermal performance; not suitable for space-constrained automotive modules. | Choose 1.5SMC11A only when legacy board layout mandates SMC package; otherwise SMB10J11-E3/5B offers superior power density and AEC-Q101 assurance. |
Compared with SMBJ11A-E3/5B, SMB10J11-E3/5B offers identical protection performance in the same compact DO-214AA package; versus 1.5SMC11A, it delivers 35 % smaller footprint and 35 % lower thermal resistance-critical for high-reliability automotive and dense industrial PCBs.

FAQ
What is the clamping voltage of SMB10J11-E3/5B at its rated peak pulse current?
The SMB10J11-E3/5B has a maximum clamping voltage (VC) of 18.2 V at its specified peak pulse current (IPPM) of 54.9 A, measured under the standard 10/1000 µs waveform. This value is guaranteed per Vishay Document Number 88422 and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The SMB10J11-E3/5B maintains this clamping performance across its full operating temperature range.
Is SMB10J11-E3/5B qualified for automotive applications?
Yes, SMB10J11-E3/5B is AEC-Q101 qualified, as confirmed in the Vishay datasheet revision 12-Nov-12 (Document Number 88422). This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing-ensuring reliability in engine control, body electronics, and ADAS systems. The SMB10J11-E3/5B carries the HE3 suffix variant for explicit AEC-Q101 marking, though the E3/5B version shares the same die and qualification.
What is the standoff voltage (VWM) rating for SMB10J11-E3/5B?
The standoff voltage (VWM) for SMB10J11-E3/5B is 11 V, representing the maximum continuous reverse voltage the device can block without entering avalanche conduction. This rating allows safe integration into 12 V nominal automotive and industrial systems with sufficient margin above typical operating voltage. The SMB10J11-E3/5B exhibits only 5.0 µA maximum reverse leakage at this voltage, preserving system efficiency.
Does SMB10J11-E3/5B have a bidirectional variant?
No, SMB10J11-E3/5B is strictly unidirectional, indicated by the "A" suffix and cathode band marking. Vishay offers a separate bidirectional variant-SMB8J11CA-in the same DO-214AA package, with matching VWM (11 V) and VC (18.2 V) but rated for 800 W peak pulse power and 44.0 A IPPM. The SMB10J11-E3/5B must not be substituted with SMB8J11CA without verifying circuit polarity and surge energy requirements.
What packaging format does SMB10J11-E3/5B ship in?
SMB10J11-E3/5B ships in 13-inch diameter plastic tape and reel format, with a base quantity of 3200 units per reel (ordering code suffix "5B"). The tape complies with EIA-481 standards and supports high-speed automated pick-and-place assembly. Each unit weighs 0.106 g, and the reel configuration ensures consistent feeding and minimal component damage during SMT line operation. The SMB10J11-E3/5B is also available in 7-inch reels (suffix "52") for lower-volume prototyping.
