Product details
Overview
SMA5J13CA-E3/61 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on signal and power lines. It features a 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR), 500 W peak pulse power (10/1000 µs), clamping voltage of 21.5 V at 23.3 A, and operates from –55 °C to +150 °C - used in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMA5J13CA-E3/61 datasheet, SMA5J13CA-E3/61 pinout, SMA5J13CA-E3/61 application, or SMA5J13CA-E3/61 equivalent, key selection criteria include bidirectional clamping capability, 500 W surge rating, DO-214AC thermal performance (RθJA = 80 °C/W), AEC-Q101 qualification path (via HE3 suffix), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode uses a glass-passivated silicon junction to achieve sub-nanosecond response time and low incremental surge resistance. Its bidirectional symmetry ensures identical clamping behavior in both polarities, with electrical characteristics fully specified per ANSI/IEEE C62.35 for transient suppression.
The device is rated for non-repetitive 10/1000 µs waveform surges up to 500 W, derated linearly above 25 °C ambient per Fig. 2, and supports peak forward surge current of 40 A only in unidirectional variants - not applicable to SMA5J13CA-E3/61 due to its bidirectional construction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 14.4 V / 15.9 V at 1 mA - guaranteed breakdown threshold defining turn-on consistency |
| VC @ IPPM | 21.5 V at 23.3 A - clamped voltage during full 500 W surge, limiting downstream stress |
| PPPM | 500 W - peak pulse power handling for 10/1000 µs transients, validated on 5.0 mm × 5.0 mm Cu pads |
| ID @ VWM | 1.0 µA - ultra-low leakage ensuring minimal standby power loss in high-impedance circuits |
| TJ range | –55 °C to +150 °C - enables deployment in under-hood automotive and industrial control environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13CA | Lower PPPM (400 W vs. 500 W); same VWM/VBR; higher VC (23.2 V) | Limited to lower-energy transients (e.g., IEC 61000-4-4); unsuitable for ISO 7637-2 Pulse 5a | Select SMA5J13CA-E3/61 when 500 W surge headroom or tighter clamping is required. |
| SMBJ13CA | Same 500 W rating but SMB (DO-214AA) package - 2.5× larger footprint and 30 % higher RθJA | Preferred where board space allows and thermal margin is constrained by enclosure airflow | Choose SMA5J13CA-E3/61 for space-constrained designs needing DO-214AC's 50 % smaller area. |
Compared with SMAJ13CA and SMBJ13CA, SMA5J13CA-E3/61 delivers superior power density (500 W in DO-214AC), tighter clamping (21.5 V), and direct compatibility with high-speed SMT lines - making it optimal for next-gen automotive and industrial modules where size, surge margin, and manufacturability are co-constrained.

FAQ
What is the clamping voltage of SMA5J13CA-E3/61 at its rated peak pulse current?
The SMA5J13CA-E3/61 has a maximum clamping voltage (VC) of 21.5 V at its peak pulse current (IPPM) of 23.3 A, measured under the standard 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during surge events. The SMA5J13CA-E3/61 achieves this with low incremental surge resistance, minimizing overshoot beyond VC.
Is SMA5J13CA-E3/61 suitable for automotive applications?
SMA5J13CA-E3/61 itself is RoHS-compliant commercial grade (E3 suffix), not AEC-Q101 qualified. However, the identical device with HE3 suffix (e.g., SMA5J13CAHE3_A) is AEC-Q101 qualified and shares the same electrical specs and DO-214AC package. For automotive use, specify the HE3 or HM3 variant - SMA5J13CA-E3/61 serves as the baseline design reference for those qualified versions.
How does the bidirectional configuration of SMA5J13CA-E3/61 affect its mounting and layout?
The SMA5J13CA-E3/61 has no polarity marking - unlike unidirectional variants, it lacks a cathode band. This simplifies PCB layout by eliminating orientation constraints during placement and allows symmetric routing on differential lines. Layout must still follow Vishay's recommended 5.0 mm × 5.0 mm copper pad per terminal to maintain rated 500 W surge capability and thermal performance.
What is the junction-to-ambient thermal resistance (RθJA) of SMA5J13CA-E3/61?
The typical junction-to-ambient thermal resistance (RθJA) of SMA5J13CA-E3/61 is 80 °C/W, measured on a standard JEDEC test board with 5.0 mm × 5.0 mm copper pads per terminal. This value assumes no additional heatsinking and defines the steady-state temperature rise under DC bias; for transient surges, thermal impedance curves (Fig. 5) govern short-duration heating behavior.
Can SMA5J13CA-E3/61 be used in place of a unidirectional TVS like SMA5J13A?
No - SMA5J13CA-E3/61 is bidirectional and cannot replace unidirectional SMA5J13A in circuits requiring DC blocking or polarity-sensitive clamping (e.g., power rail protection with ground-referenced anode). While both share VWM = 13 V and similar VBR, SMA5J13A conducts forward current below VF ≈ 3.5 V, whereas SMA5J13CA-E3/61 blocks in both directions until breakdown. Substitution requires full circuit analysis.
