Product details
Overview
SMA5J16C-E3/61 from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, designed for clamping voltage transients on signal and power lines. It features a 16 V stand-off voltage (VWM), 17.8–19.7 V breakdown voltage (VBR), 500 W peak pulse power (10/1000 µs), 19.2 A peak pulse current (IPPM), and clamps to ≤26.0 V at IPPM. It is used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the SMA5J16C-E3/61 datasheet, SMA5J16C-E3/61 pinout, SMA5J16C-E3/61 application, or SMA5J16C-E3/61 equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, 500 W surge rating, DO-214AC thermal performance (RθJA = 80 °C/W), and RoHS-compliant matte tin terminations.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, with identical electrical characteristics forward and reverse. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 µA at VWM), while its low incremental surge resistance enables effective clamping during fast transients (e.g., ISO 7637-2 pulse 1/2a/5a).
The device is rated for TJ = –55 °C to +150 °C and meets MSL Level 1 per J-STD-020 (260 °C peak reflow). Its DO-214AC package provides mechanical robustness and thermal dissipation suitable for automated SMT placement on 5.0 mm × 5.0 mm copper pads per terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - Maximum continuous reverse stand-off voltage before clamping begins; defines operating margin for protected circuitry. |
| VBR min/max | 17.8 V / 19.7 V at 1.0 mA - Verified breakdown threshold range ensuring reliable turn-on under ESD or surge events. |
| IPPM | 19.2 A (10/1000 µs) - Peak surge current it safely shunts without failure; derived from 500 W PPPM rating. |
| VC | ≤26.0 V at IPPM - Clamped voltage seen by downstream ICs; guarantees safe stress level for 24 V logic or analog interfaces. |
| TJ max | +150 °C - Maximum junction temperature enabling operation in under-hood automotive or industrial enclosures. |
| RθJA | 80 °C/W - Thermal resistance from junction to ambient; informs PCB pad design and power derating above 25 °C. |
Pinout & Package
DO-214AC (SMA) surface-mount package: molded epoxy case meeting UL 94 V-0, matte tin-plated leads solderable per J-STD-020 and JESD 22-B102, no polarity marking (bi-directional).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional transient conduction path | No functional polarity; terminals interchangeable - enables placement without orientation check in automated assembly. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for engine control, ADAS, and body electronics. |
| Glass passivated junction | Stable VBR tolerance and low leakage (<1.0 µA) over lifetime - critical for long-term sensor interface integrity. |
| Low incremental surge resistance | Enables tight VC–VBR margin (26.0 V vs. 19.7 V max), minimizing voltage overshoot during fast transients like EFT or lightning surges. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without preconditioning - eliminates moisture sensitivity handling overhead. |
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 |
|---|---|---|---|
| Littelfuse SMAJ16CA | Same DO-214AC package, 16 V VWM, but lower PPPM (400 W) and higher VC (28.5 V); not AEC-Q101 qualified. | Acceptable for commercial-grade industrial or telecom use where 500 W rating and automotive qualification are not required. | Select SMA5J16C-E3/61 when AEC-Q101 compliance, 500 W rating, or tighter VC is mandatory. |
| ON Semiconductor 1.5SMC16CA | Higher package thermal resistance (RθJA ≈ 100 °C/W), same VWM/VBR, but lower IPPM (16.7 A) and VC = 26.0 V; AEC-Q101 qualified only in HE3 variant. | Requires larger PCB copper area for thermal management; HE3 version needed for automotive use. | Choose SMA5J16C-E3/61 for guaranteed AEC-Q101 qualification in E3 suffix and superior thermal performance on standard pads. |
Compared with SMAJ16CA and 1.5SMC16CA, SMA5J16C-E3/61 delivers higher surge robustness (500 W), lower thermal resistance (80 °C/W), and factory-certified AEC-Q101 qualification in the commercial-grade E3 variant - making it optimal for space-constrained automotive and industrial designs requiring proven reliability without layout redesign.

FAQ
What is the polarity configuration of SMA5J16C-E3/61?
SMA5J16C-E3/61 is a bi-directional TVS diode with symmetrical anode/cathode terminals and no polarity marking. Its electrical characteristics apply identically in both directions, enabling flexible PCB placement without orientation constraints - unlike uni-directional variants such as SMA5J16A.
Is SMA5J16C-E3/61 qualified for automotive applications?
Yes, SMA5J16C-E3/61 is AEC-Q101 qualified per the Vishay datasheet (Document Number: 88875, Revision: 24-Oct-12). This qualification covers stress tests including temperature cycling, high-temperature reverse bias, and ESD, confirming suitability for under-hood and chassis-mounted automotive electronics.
What is the maximum clamping voltage of SMA5J16C-E3/61 at rated surge current?
The maximum clamping voltage (VC) of SMA5J16C-E3/61 is 26.0 V when subjected to its rated 10/1000 µs peak pulse current of 19.2 A. This value is measured per standard test conditions and ensures downstream ICs see limited overvoltage during surge events.
Does SMA5J16C-E3/61 meet RoHS and lead-free assembly requirements?
Yes, SMA5J16C-E3/61 is RoHS-compliant (per Directive 2011/65/EU) and features matte tin-plated leads qualified for lead-free reflow soldering up to 260 °C peak temperature (MSL Level 1). The "E3" suffix explicitly denotes RoHS-compliant commercial-grade construction.
How does the thermal resistance of SMA5J16C-E3/61 affect PCB layout?
SMA5J16C-E3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain TJ ≤150 °C under 500 W surge, designers must provide adequate copper area and avoid excessive ambient temperature rise - especially in enclosed automotive housings.
