Product details
Overview
SMCJ16-E3/57T from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 16 V stand-off voltage (VWM), 26.0 V maximum clamping voltage (VC) at 57.7 A peak pulse current (IPPM), and 1500 W peak pulse power dissipation (10/1000 µs waveform), making it suitable for automotive power supply input protection and industrial sensor interface surge suppression.
For engineers reviewing the SMCJ16-E3/57T datasheet, SMCJ16-E3/57T pinout, SMCJ16-E3/57T application, or SMCJ16-E3/57T equivalent, key selection criteria include its AEC-Q101 qualification, low incremental surge resistance, glass-passivated junction, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads per terminal.
Technical Context
The SMCJ16-E3/57T operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its breakdown threshold (VBR = 17.8–19.7 V at IT = 1.0 mA). Its clamping action limits transient-induced voltages to ≤26.0 V under 57.7 A surge, protecting downstream ICs such as microcontrollers and CAN transceivers.
Thermally, it exhibits RθJA = 75 °C/W (typ.) and RθJL = 15 °C/W (typ.), enabling reliable operation up to TJ = +150 °C. The device meets MSL Level 1 per J-STD-020 and passes JESD 201 Class 1A whisker testing, confirming suitability for high-reliability surface-mount assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin for 12 V systems. |
| VBR min/max | 17.8 V / 19.7 V at 1.0 mA - Confirmed breakdown range ensures predictable turn-on during transients without premature conduction. |
| VC @ IPPM | 26.0 V at 57.7 A - Clamping voltage under 10/1000 µs surge; guarantees protected circuit sees <26 V during worst-case lightning or ESD events. |
| PPPM | 1500 W - Peak pulse power handling capacity; supports high-energy surges common in automotive load-dump and inductive switching. |
| IFSM | 200 A - Non-repetitive forward surge rating (8.3 ms half-sine); enables survival of short-circuit fault currents in power supplies. |
| TJ max | +150 °C - Maximum junction temperature; allows operation in under-hood automotive environments and industrial enclosures. |
| Package | DO-214AB (SMCJ) - Standardized surface-mount outline with 0.320" body length and cathode band marking; compatible with JEDEC-compliant pick-and-place. |
Pinout & Package
DO-214AB (SMCJ) package: molded plastic case with matte tin-plated leads, polarity indicated by cathode band on one end. Designed for soldering per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point (for uni-directional conduction) | Connected to system ground or low-side return path; conducts during reverse-biased transient suppression. |
| Cathode | Reverse voltage sensing node | Connected to protected line (e.g., 12 V rail); initiates avalanche breakdown when VAK > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and body electronics, ensuring reliability across temperature and vibration stress. |
| Glass passivated chip junction | Enhances long-term stability and moisture resistance versus epoxy-passivated alternatives, critical for industrial outdoor deployments. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ISO 7637-2 Pulse 1/2a), improving protection margin for sensitive logic inputs. |
| MSL Level 1 (260 °C peak) | Enables single-reflow soldering without preconditioning; eliminates moisture-related popcorning risk in high-volume manufacturing. |
| RoHS-compliant (E3 suffix) | Meets EU Directive 2011/65/EU; contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-E3/61T | Lower PPPM (400 W), smaller SMA package (DO-214AC), higher VC (33.0 V at 12.3 A) | Targeted for space-constrained consumer electronics; insufficient for automotive load dump. | Select when board area is limited and surge energy is ≤400 W (e.g., USB port protection). |
| SMCJ16AHE3/57T | Identical electrical specs but AEC-Q101 qualified (HE3 suffix); same DO-214AB package and thermal performance. | Required for automotive OEM designs requiring full qualification documentation and traceability. | Choose for Tier 1 automotive programs where AEC-Q101 compliance is mandatory and documented test reports are needed. |

FAQ
What is the breakdown voltage range of the SMCJ16-E3/57T?
The SMCJ16-E3/57T has a guaranteed breakdown voltage (VBR) range of 17.8 V to 19.7 V at a test current of 1.0 mA, measured per ANSI/IEEE C62.35. This range ensures consistent turn-on behavior across production lots and validates its suitability for 12 V nominal systems where margin above VWM = 16 V is required. The SMCJ16-E3/57T maintains this specification across its full operating temperature range.
Is the SMCJ16-E3/57T suitable for automotive applications?
The SMCJ16-E3/57T is RoHS-compliant and rated for operation from –55 °C to +150 °C, but it carries the commercial-grade E3 suffix-not the HE3 AEC-Q101 qualified version. While its electrical and thermal specs meet many automotive requirements, formal AEC-Q101 qualification is absent. For production automotive use, SMCJ16AHE3/57T is the certified alternative. The SMCJ16-E3/57T remains appropriate for non-OEM automotive aftermarket or industrial applications with similar environmental demands.
What is the maximum clamping voltage of the SMCJ16-E3/57T under surge conditions?
The SMCJ16-E3/57T clamps to a maximum of 26.0 V when subjected to its rated peak pulse current of 57.7 A (10/1000 µs waveform). This value is measured under standardized test conditions with 0.31" × 0.31" copper pads per terminal and represents the upper limit of voltage seen by protected circuitry during worst-case transients. This clamping performance is integral to the SMCJ16-E3/57T's role in safeguarding 3.3 V and 5 V logic interfaces.
Does the SMCJ16-E3/57T have polarity marking, and how is it identified?
Yes, the SMCJ16-E3/57T is unidirectional and features a visible cathode band on the DO-214AB (SMCJ) package body. This band identifies the cathode terminal, which must be connected to the line being protected (e.g., 12 V rail), while the anode connects to ground. The marking complies with industry-standard diode polarity conventions and is verified per JEDEC outline drawings. No marking appears on bi-directional variants, but the SMCJ16-E3/57T always includes the band.
What is the surge current rating of the SMCJ16-E3/57T, and how is it defined?
The SMCJ16-E3/57T supports a peak pulse current (IPPM) of 57.7 A under a 10/1000 µs double-exponential surge waveform, corresponding to its 1500 W peak pulse power rating. Additionally, it withstands a non-repetitive forward surge current (IFSM) of 200 A for an 8.3 ms half-sine wave-critical for surviving short-circuit faults in power distribution networks. Both ratings are validated per the Vishay datasheet 88394 and apply at TA = 25 °C with specified PCB layout.
