Product details
Overview
SMCJ16AHE3/57T from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for robust overvoltage protection of sensitive electronics. It features a 16 V standoff voltage (VWM), 26.0 V maximum clamping voltage (VC) at 57.7 A peak pulse current (IPPM), and 1500 W peak pulse power (10/1000 µs waveform), commonly deployed on power rails and signal lines in automotive ECUs and industrial motor controllers.
For engineers reviewing the SMCJ16AHE3/57T datasheet, SMCJ16AHE3/57T pinout, SMCJ16AHE3/57T application, or SMCJ16AHE3/57T 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.
Technical Context
The SMCJ16AHE3/57T operates as a unidirectional avalanche-clamping device, triggered when reverse voltage exceeds its 17.8–19.7 V breakdown range (VBR at 1.0 mA). Its fast response time (<1 ps) and low clamping ratio (VC/VWM ≈ 1.625) enable effective suppression of ESD, lightning-induced surges, and inductive switching transients without affecting normal circuit operation.
Thermally, it exhibits RθJA = 75 °C/W and RθJL = 15 °C/W, supporting reliable operation up to TJ = +150 °C. The matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability standards, and the device is rated MSL Level 1 (260 °C peak reflow).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 17.8 V / 19.7 V at 1.0 mA - Ensures precise, repeatable avalanche turn-on threshold |
| VC @ IPPM | 26.0 V at 57.7 A - Limits downstream voltage stress during 1500 W transient events |
| IPPM | 57.7 A (10/1000 µs) - Supports high-energy surge handling on 12 V/24 V systems |
| PPPM | 1500 W - Enables protection against ISO 7637-2 Pulse 1, 2a, 3a/b, and IEC 61000-4-5 surges |
| TJ max. | +150 °C - Allows use in under-hood automotive environments and enclosed industrial enclosures |
| Leakage ID | 1.0 µA at VWM - Minimizes standby power loss in battery-powered systems |

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-E3/61 | Lower PPPM (400 W), smaller SMA package (DO-214AC), higher VC (27.7 V) | Suitable for space-constrained consumer PCBs but insufficient for automotive load dump | Select when board area is critical and surge energy ≤ 400 W |
| SMCJ16CAHE3/57T | Bidirectional version; same VWM, VBR, and VC; symmetric clamping in both polarities | Required for AC-coupled or floating signal lines where polarity reversal may occur | Choose for differential data lines (e.g., RS-485) or transformer-isolated interfaces |
Compared with SMAJ16A-E3/61 and SMCJ16CAHE3/57T, the SMCJ16AHE3/57T delivers 275 % higher surge power handling and automotive-grade qualification-making it the preferred choice for 12 V/24 V vehicle subsystems and industrial power supplies demanding AEC-Q101 compliance and 1500 W immunity.

FAQ
What is the clamping voltage of the SMCJ16AHE3/57T at its rated peak pulse current?
The SMCJ16AHE3/57T has a maximum clamping voltage (VC) of 26.0 V when subjected to its rated 10/1000 µs peak pulse current of 57.7 A. This value is measured under standardized test conditions per ANSI/IEEE C62.35 and ensures predictable overvoltage limiting during surge events. The SMCJ16AHE3/57T maintains this clamping performance across its full operating temperature range (−55 °C to +150 °C), making it suitable for under-hood automotive applications.
Is the SMCJ16AHE3/57T qualified for automotive applications?
Yes, the SMCJ16AHE3/57T is AEC-Q101 qualified, as confirmed by Vishay's official documentation and ordering code suffix "HE3". This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and ESD per JESD47, validating its suitability for automotive powertrain, chassis, and body electronics. The SMCJ16AHE3/57T meets the reliability and lifetime requirements for automotive-grade production, unlike commercial-only variants such as SMCJ16A-E3/57T.
What is the standoff voltage and breakdown voltage range for the SMCJ16AHE3/57T?
The SMCJ16AHE3/57T has a standoff voltage (VWM) of 16 V and a guaranteed breakdown voltage (VBR) range of 17.8 V to 19.7 V at 1.0 mA test current. This 1.9 V window ensures consistent avalanche initiation while providing margin against false triggering during normal operation. The SMCJ16AHE3/57T's VBR tolerance aligns with industry-standard TVS specifications and supports robust design against manufacturing variation and temperature drift.
Does the SMCJ16AHE3/57T have a defined thermal resistance specification?
Yes, the SMCJ16AHE3/57T specifies typical thermal resistance values of RθJA = 75 °C/W (junction-to-ambient, on recommended 8.0 mm × 8.0 mm copper pads) and RθJL = 15 °C/W (junction-to-lead). These values are critical for thermal design in high-power surge scenarios and confirm that the SMCJ16AHE3/57T can sustain repeated transients without exceeding its +150 °C maximum junction temperature. Proper PCB copper pour design directly impacts actual RθJA performance in the final application.
How does the SMCJ16AHE3/57T differ from the bidirectional SMCJ16CAHE3/57T?
The SMCJ16AHE3/57T is unidirectional, with polarity marked by a cathode band and intended for DC rail protection where current flows in one direction. In contrast, the SMCJ16CAHE3/57T is bidirectional, lacking polarity marking and providing symmetrical clamping for AC or floating signals. Both share identical VWM (16 V), VBR, VC, and PPPM (1500 W), but the SMCJ16AHE3/57T cannot replace the CA version in bidirectional applications without circuit redesign.
