Product details
Overview
SMA5J10-E3/61 from Vishay General Semiconductor is a unidirectional transient voltage suppressor diode in DO-214AC (SMA) package, designed for circuit protection against ESD and lightning-induced surges. It features 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR), 17.0 V clamping voltage at 29.4 A peak pulse current, and 500 W peak pulse power rating with 10/1000 µs waveform - deployed on power rails and I/O lines of automotive ECUs and industrial sensor interfaces.
For engineers reviewing the SMA5J10-E3/61 datasheet, SMA5J10-E3/61 pinout, SMA5J10-E3/61 application, or SMA5J10-E3/61 equivalent, key selection considerations include unidirectional polarity, 150 °C max junction temperature, RoHS-compliant matte tin plating, AEC-Q101 qualification status, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, delivering fast response time (<1 ns) and low incremental surge resistance to clamp transient overvoltages before downstream components are damaged. Its unidirectional configuration requires cathode-band orientation during PCB layout, and it conducts only in reverse-bias mode above VBR.
The SMA5J10-E3/61 is rated for non-repetitive 8.3 ms half-sine surge current up to 40 A (IFSM), and thermal performance is characterized by 80 °C/W junction-to-ambient resistance under standard pad layout. It meets J-STD-020 MSL Level 1 with 260 °C reflow peak.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J10AHE3/61 | AEC-Q101 qualified version with identical electrical specs; HE3 suffix indicates enhanced whisker resistance (JESD201 Class 2) | Required for automotive safety-critical modules where extended whisker reliability is mandated | Select SMA5J10AHE3/61 when AEC-Q101 compliance must be documented per component-level PPAP submission |
| 1.5SMC10A | Same VWM/VBR/VC ratings but in larger DO-214AB (SMC) package; higher thermal mass (RθJA = 50 °C/W vs. 80 °C/W) | Better suited for high-temperature ambient environments (>85 °C) or higher average surge duty cycles | Choose 1.5SMC10A when board space allows and thermal derating margin is critical for repetitive surge exposure |
Compared with SMA5J10-E3/61, SMA5J10AHE3/61 offers identical protection performance with enhanced process reliability for automotive, while 1.5SMC10A trades smaller footprint for superior thermal handling - making the SMA5J10-E3/61 optimal for space-constrained, cost-sensitive AEC-Q101-eligible designs.

FAQ
What is the polarity configuration of the SMA5J10-E3/61?
The SMA5J10-E3/61 is a unidirectional transient voltage suppressor diode. Its cathode is marked by a visible band on the DO-214AC package body, and it conducts only when reverse-biased above its breakdown voltage (11.1–12.3 V). This configuration ensures proper orientation on power rails where clamping occurs toward the protected IC's supply pin. The SMA5J10-E3/61 does not function as a bidirectional device.
Does the SMA5J10-E3/61 meet automotive qualification standards?
Yes, the SMA5J10-E3/61 is RoHS-compliant and manufactured to AEC-Q101 qualification standards for stress testing, including temperature cycling, humidity bias, and mechanical shock. While the base E3 suffix denotes commercial-grade RoHS compliance, the device shares the same die and process as AEC-Q101-qualified variants like SMA5J10AHE3/61 - enabling use in non-safety-critical automotive modules such as infotainment and body control units. The SMA5J10-E3/61 itself is not individually certified AEC-Q101, but its construction and test data align with that standard.
What is the maximum clamping voltage of the SMA5J10-E3/61 under surge conditions?
The SMA5J10-E3/61 has a maximum clamping voltage (VC) of 17.0 V at its rated peak pulse current (IPPM) of 29.4 A, measured using the standardized 10/1000 µs double-exponential waveform. This value represents the upper limit of voltage seen by downstream components during worst-case transient events. The SMA5J10-E3/61 maintains this clamping performance across its operational junction temperature range of –55 °C to +150 °C, with minor variation per thermal derating curves in the datasheet.
Can the SMA5J10-E3/61 be used in bidirectional signal line protection?
No, the SMA5J10-E3/61 is strictly unidirectional and unsuitable for bidirectional signal lines such as RS-485 or CAN bus. For those applications, a bidirectional variant like SMA5J10CA must be selected - it lacks polarity marking and provides symmetrical clamping in both directions. Using the SMA5J10-E3/61 on AC-coupled or differential lines risks forward conduction during normal operation and failure to clamp in one polarity. Always verify polarity alignment before placing the SMA5J10-E3/61 in circuit.
What is the recommended PCB pad layout for the SMA5J10-E3/61?
Vishay specifies a minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad for each terminal of the SMA5J10-E3/61 to achieve rated 500 W peak pulse power dissipation and proper thermal conduction. Pad dimensions must accommodate DO-214AC outline: 5.28 mm length, 4.50 mm width, and 2.29 mm height. Thermal vias under pads are recommended for high-reliability automotive designs. The SMA5J10-E3/61 datasheet Figure 4 provides exact land pattern dimensions and solder mask clearance guidance.
