Product details
Overview
SMCJ36C-E3/57T from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for clamping voltage transients on signal or power lines. It features a 36 V stand-off voltage (VWM), 58.1 V maximum clamping voltage (VC) at 25.8 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 µs waveform - used to protect automotive sensor interfaces and industrial I/O circuits.
For engineers reviewing the SMCJ36C-E3/57T datasheet, SMCJ36C-E3/57T pinout, SMCJ36C-E3/57T application, or SMCJ36C-E3/57T equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, low incremental surge resistance, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCJ36C-E3/57T operates as a bi-directional avalanche diode, exhibiting symmetrical breakdown behavior in both polarities with VBR min/max of 40.0 V / 44.2 V at 1 mA test current. Its clamping action begins at VWM = 36 V and limits transient voltages to ≤58.1 V under 10/1000 µs surges up to 25.8 A.
Thermally, it supports operation from –55 °C to +150 °C junction temperature, with RθJA = 75 °C/W and RθJL = 15 °C/W. It meets MSL Level 1 per J-STD-020 and is qualified to AEC-Q101 for automotive reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR (min/max) | 40.0 V / 44.2 V at IT = 1 mA - ensures reliable bi-directional breakdown within tight tolerance |
| VC @ IPPM | 58.1 V at 25.8 A - limits transient voltage seen by protected ICs during 10/1000 µs surge |
| PPPM | 1500 W - handles high-energy transients common in automotive load-dump or inductive switching |
| ID @ VWM | 1.0 µA - ultra-low leakage preserves signal integrity in high-impedance sensor lines |
| TJ Range | –55 °C to +150 °C - supports under-hood and industrial ambient conditions |
| Package | DO-214AB (SMCJ) - surface-mount, RoHS-compliant, matte tin-plated leads |
Pinout & Package
DO-214AB (SMCJ) package: molded plastic case with J-bend leads; no polarity marking for bi-directional devices; terminals are matte tin plated, solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load-dump and ESD events in vehicle ECUs. IC Role / Device Role / Timing Role: Bi-directional TVS clamp placed directly at connector or IC pin to shunt transients before they reach sensitive front-end circuitry. Use Value: Clamps 36 V nominal lines to ≤58.1 V during 1500 W surges, preserving signal fidelity and preventing latch-up in 3.3 V/5 V interface ICs. | Use Scenario: Safeguarding digital and analog input/output channels of programmable logic controllers against field-induced surges and ground bounce. IC Role / Device Role / Timing Role: Standoff-rated TVS deployed across isolated 24 V DC I/O lines to absorb repetitive switching transients from solenoids and relays. Use Value: 1.0 µA leakage at 36 V enables use on high-Z analog inputs without measurement drift; AEC-Q101 grade assures long-term stability in harsh factory environments. |
| Telecom Line Interface | Consumer Power Adapter Input |
Use Scenario: Transient suppression on Ethernet PHY magnetics secondary side or RS-485 differential pairs exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Bi-directional clamping device placed across differential lines to equalize voltage swing and prevent receiver damage. Use Value: Symmetrical VBR (40.0–44.2 V) ensures balanced clamping on both polarities, maintaining common-mode rejection while limiting differential overvoltage. | Use Scenario: Secondary-side overvoltage protection in AC/DC adapters and USB PD power bricks where 36 V rails interface with USB-C CC logic or monitoring ICs. IC Role / Device Role / Timing Role: Standoff-limited TVS on 36 V auxiliary supply rail to absorb capacitor discharge spikes and rectifier reverse recovery transients. Use Value: 58.1 V clamping voltage provides ≥12 V margin above 36 V rail, allowing safe operation of 50 V-rated monitoring ICs without derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC36C-TB | Same VWM (36 V) and VC (58 V), but lower PPPM (1000 W); TO-220AC package, through-hole mount | Not suitable for high-density SMT designs; better heat sinking for sustained surge duty cycles | Select SAC36C-TB only when board layout allows through-hole mounting and thermal mass exceeds SMCJ's capability |
| TPSMD36CA | Identical VWM (36 V), VC (58.1 V), and PPPM (1500 W); same DO-214AB package; AEC-Q101 qualified | Functionally interchangeable; minor differences in leakage (1.0 µA vs. 0.5 µA) and thermal resistance (RθJA 75 vs. 70 °C/W) | TPSMD36CA is a direct functional alternative with near-identical specs - verify layout compatibility and sourcing lead time |
Compared with SAC36C-TB and TPSMD36CA, the SMCJ36C-E3/57T offers optimal balance of high-power SMT integration, AEC-Q101 compliance, and standardized tape-and-reel delivery (850 pcs/7″ reel), making it preferred for automotive and industrial volume production where placement automation and reliability validation are critical.

FAQ
What is the clamping voltage of the SMCJ36C-E3/57T under a 10/1000 µs surge?
The SMCJ36C-E3/57T has a maximum clamping voltage (VC) of 58.1 V at 25.8 A peak pulse current (IPPM) under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in the Vishay datasheet (Doc. #88394, page 2). The SMCJ36C-E3/57T maintains this clamping performance across its full operating temperature range.
Is the SMCJ36C-E3/57T suitable for automotive applications?
Yes, the SMCJ36C-E3/57T is AEC-Q101 qualified and rated for junction temperatures from –55 °C to +150 °C, making it suitable for under-hood and body-control module applications. Its bi-directional architecture, low leakage (1.0 µA), and 1500 W surge capability align with ISO 7637-2 and ISO 16750-2 requirements. The SMCJ36C-E3/57T is explicitly listed in Vishay's AEC-Q101 qualified product table.
Does the SMCJ36C-E3/57T have polarity markings?
No, the SMCJ36C-E3/57T does not have polarity markings because it is a bi-directional TVS diode. As stated in the Vishay datasheet (page 1), "no marking on bi-directional types." Both terminals are functionally identical, enabling symmetric placement across AC-coupled or bidirectional DC signal paths without orientation constraints.
What is the thermal resistance of the SMCJ36C-E3/57T?
The SMCJ36C-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead resistance (RθJL) of 15 °C/W, measured on the minimum recommended pad layout (0.31″ × 0.31″ copper pads per terminal). These values are specified in the Thermal Characteristics table (page 3) of the Vishay datasheet for SMCJ5.0A–SMCJ188CA. The SMCJ36C-E3/57T relies on PCB copper area for effective heat dissipation during surge events.
What packaging format is used for the SMCJ36C-E3/57T?
The SMCJ36C-E3/57T is supplied in 7″ diameter plastic tape and reel format, with 850 units per reel (ordering code suffix "57T"). It uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and meets JESD 201 class 1A whisker testing. This packaging supports high-speed pick-and-place assembly and is documented in the Ordering Information section (page 3) of the Vishay datasheet.
