Product details
Overview
SMA5J10C-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 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR), 17.0 V maximum clamping voltage (VC) at 29.4 A peak pulse current, and 500 W peak pulse power rating with 10/1000 µs waveform - used to protect automotive sensor interfaces and industrial I/O ports against ESD and load dump.
For engineers reviewing the SMA5J10C-E3/61 datasheet, SMA5J10C-E3/61 pinout, SMA5J10C-E3/61 application, or SMA5J10C-E3/61 equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, RoHS-compliant matte tin terminations, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, enabling protection of AC-coupled or floating signal paths without polarity constraints. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and low incremental surge resistance, critical for repeatable clamping performance under repetitive transients.
The device is rated for junction temperatures from –55 °C to +150 °C and exhibits typical thermal resistance of 80 °C/W (junction-to-ambient) and 25 °C/W (junction-to-lead), supporting reliable operation in thermally constrained automotive and industrial PCB layouts with minimum recommended pad area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating window for protected circuitry. |
| VBR (min/max) | 11.1 V / 12.3 V - Breakdown occurs within this range at 1 mA test current; ensures predictable turn-on threshold across production lot. |
| VC @ IPPM | 17.0 V - Clamped voltage at 29.4 A peak pulse current; limits downstream voltage stress during 10/1000 µs surge events. |
| PPPM | 500 W - Peak pulse power handling per 10/1000 µs waveform; supports robust protection against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 surges. |
| IPPM | 29.4 A - Peak pulse current corresponding to VC; determines minimum trace width and layout clearance needed for surge path. |
| TJ max | +150 °C - Maximum junction temperature; enables use in under-hood automotive environments and high-ambient industrial enclosures. |
| MSL Level | Level 1 (per J-STD-020) - No floor life limitation; can be stored indefinitely at ≤30 °C/60% RH and mounted without baking. |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, bi-directional configuration with no polarity marking. Case meets UL 94 V-0 flammability rating; matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional surge conduction path | No functional distinction between terminals; either terminal serves as anode or cathode depending on transient polarity - eliminates orientation errors during placement. |
| Case (cathode band absent) | Non-polarized package body | DO-214AC housing provides mechanical support and thermal dissipation; absence of band confirms bi-directional construction per Vishay marking convention. |

FAQ
What does the "C" suffix in SMA5J10C-E3/61 indicate?
The "C" suffix in SMA5J10C-E3/61 denotes a bi-directional configuration, meaning the device clamps voltage transients equally in both polarities. Per Vishay documentation, this is functionally identical to the "CA" suffix variant (e.g., SMA5J10CA-E3/61), and both share identical VWM, VBR, VC, and PPPM specifications. The SMA5J10C-E3/61 has no polarity marking on the DO-214AC package body.
Is SMA5J10C-E3/61 AEC-Q101 qualified?
Yes, SMA5J10C-E3/61 is AEC-Q101 qualified, as confirmed in the Vishay datasheet revision 24-Oct-12 (Document Number: 88875). This qualification covers stress tests including HTGB, HTRB, TCT, and ESD, validating its suitability for automotive applications such as engine control units, body electronics, and ADAS sensor modules.
What is the maximum clamping voltage of SMA5J10C-E3/61 and at what current is it specified?
The maximum clamping voltage (VC) of SMA5J10C-E3/61 is 17.0 V, measured at a peak pulse current (IPPM) of 29.4 A using a 10/1000 µs waveform. This value is guaranteed across the operating temperature range and defines the upper voltage limit imposed on protected circuitry during surge events.
Does SMA5J10C-E3/61 require orientation during PCB placement?
No, SMA5J10C-E3/61 does not require specific orientation during PCB placement because it is a bi-directional TVS diode with symmetrical terminals and no cathode band marking. Either end may connect to line or ground - this eliminates assembly errors and simplifies automated pick-and-place programming for the DO-214AC (SMA) package.
What is the thermal resistance of SMA5J10C-E3/61 and how does it affect layout design?
SMA5J10C-E3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W and junction-to-lead (RθJL) of 25 °C/W. To maintain TJ ≤ 150 °C under worst-case 500 W surge conditions, PCB layout must use minimum recommended 5.0 mm × 5.0 mm copper pads per terminal - verified in Vishay's thermal derating curves (Fig. 2).
