Product details
Overview
SMB10J36-E3/5B 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 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR), 58.1 V maximum clamping voltage (VC) at 17.2 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed in automotive power supply inputs and industrial sensor interfaces.
For engineers reviewing the SMB10J36-E3/5B datasheet, SMB10J36-E3/5B pinout, SMB10J36-E3/5B application, or SMB10J36-E3/5B equivalent, key selection criteria include clamping performance under 10/1000 µs transients, AEC-Q101 qualification for automotive use, RoHS-compliant matte tin terminations, 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: it remains high-impedance below 36 V (VWM), triggers avalanche conduction at 40.0–44.2 V (VBR @ 1 mA), and limits transient voltages to ≤58.1 V during 17.2 A surges. Its glass-passivated junction ensures stable breakdown and low leakage (<1.0 µA at VWM).
Thermal design relies on RθJA = 72 °C/W (typ.) and RθJL = 20 °C/W (typ.), enabling operation from –55 °C to +150 °C junction temperature. The device meets MSL Level 1 (J-STD-020) and JESD201 Class 1A whisker resistance, supporting lead-free reflow up to 260 °C peak.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A-E3/5B | Same VWM (36 V), VBR (40.0–44.2 V), and VC (58.1 V); identical DO-214AA package and AEC-Q101 qualification. | No functional difference; SMBJ36A-E3/5B is Vishay's newer standardized part number for same die and construction. | Select SMBJ36A-E3/5B for new designs to align with current Vishay naming convention and long-term availability roadmap. |
| 1.5SMC36A | Same electrical specs (VWM = 36 V, VC = 58.1 V), but larger DO-214AB (SMC) package (7.11 × 6.22 mm vs. 4.57 × 3.94 mm) and higher RθJA (50 °C/W). | Requires PCB layout change; better suited for higher-power derating needs or legacy SMC-footprint designs. | Choose 1.5SMC36A only when thermal budget permits larger footprint or when replacing existing SMC-based designs. |
Compared with SMB10J36-E3/5B, SMBJ36A-E3/5B offers identical protection performance in the same compact DO-214AA package and is preferred for new designs, while 1.5SMC36A trades size for marginally improved thermal resistance but demands PCB redesign.

FAQ
What is the clamping voltage of SMB10J36-E3/5B under a 10/1000 µs surge?
The SMB10J36-E3/5B clamps to a maximum of 58.1 V when subjected to its rated peak pulse current of 17.2 A with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's datasheet revision 12-Nov-12, ensuring predictable overvoltage limiting for protected ICs downstream of SMB10J36-E3/5B.
Is SMB10J36-E3/5B qualified for automotive applications?
Yes, SMB10J36-E3/5B is AEC-Q101 qualified, having passed stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and highly accelerated stress testing (HAST). This certification validates its suitability for automotive powertrain, body control, and infotainment systems where SMB10J36-E3/5B serves as primary surge protection.
What does the "E3/5B" suffix mean in SMB10J36-E3/5B?
The "E3" denotes RoHS-compliant, commercial-grade matte tin plating meeting JESD201 Class 1A whisker resistance; "5B" specifies packaging in 13-inch diameter plastic tape and reel with 3200 units per reel. This configuration ensures compatibility with high-speed pick-and-place equipment and supports full traceability for SMB10J36-E3/5B in production environments.
How does SMB10J36-E3/5B differ from bi-directional variants like SMB8J36CA?
SMB10J36-E3/5B is unidirectional with cathode marking and conducts only in reverse bias, making it ideal for DC rail protection. In contrast, SMB8J36CA is bi-directional (no polarity marking), offering symmetric clamping for AC-coupled or floating signal lines - a functional distinction that makes SMB10J36-E3/5B unsuitable for bidirectional applications unless paired with additional circuitry.
What thermal considerations apply when using SMB10J36-E3/5B in high-density PCB layouts?
SMB10J36-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W when mounted on 0.2" × 0.2" copper pads. To maintain TJ ≤ 150 °C under repeated surges, ensure adequate copper area, avoid thermal crowding, and verify layout against Vishay's recommended pad dimensions - critical for sustained reliability of SMB10J36-E3/5B in enclosed industrial modules.
