Product details
Overview
SMA5J5.0AHE3/5A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on DC power rails and signal lines. It features a 5.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR) at 10 mA, 500 W peak pulse power (10/1000 µs), 54.3 V clamping voltage at 9.2 A peak pulse current, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMA5J5.0AHE3/5A datasheet, SMA5J5.0AHE3/5A pinout, SMA5J5.0AHE3/5A application, or SMA5J5.0AHE3/5A equivalent, key selection criteria include clamping performance under 10/1000 µs transients, junction temperature derating above 25 °C, unidirectional polarity marking (cathode band), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR, it avalanches to divert surge current away from downstream ICs or MOSFETs. Its glass-passivated junction ensures stable breakdown and low leakage (<800 µA at 5.0 V), while MSL Level 1 rating supports lead-free reflow up to 260 °C.
Thermal design relies on RθJA = 80 °C/W and RθJL = 25 °C/W; maximum junction temperature is 150 °C. The device sustains 40 A non-repetitive forward surge (8.3 ms half-sine) and exhibits fast response time (<1 ns), making it suitable for protecting sensitive inputs against ESD, load dump, and inductive switching events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse operating voltage before conduction begins; defines safe DC rail margin. |
| VBR min/max | 6.4 V / 7.07 V at 10 mA - Ensures reliable avalanche initiation within tight tolerance for predictable clamping onset. |
| VC @ IPPM | 54.3 V at 9.2 A - Clamping voltage during 10/1000 µs surge; limits stress on protected circuitry. |
| PPPM | 500 W - Peak pulse power handling capacity; determines survivability against standardized lightning surges. |
| ID @ VWM | ≤800 µA - Low reverse leakage preserves power efficiency and avoids false triggering in low-current systems. |
| TJ max | +150 °C - Enables operation in under-hood automotive environments and industrial enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J5.0A-E3/5A | No AEC-Q101 qualification; commercial-grade only; identical electrical specs and package. | Not approved for automotive production; suitable for consumer or industrial prototypes. | Select when AEC-Q101 is not required and cost sensitivity outweighs qualification needs. |
| SMA5J5.0CAHE3/5A | Bidirectional variant; symmetric VBR (6.4–7.25 V) and same PPPM/VC; no polarity marking. | Used where AC-coupled or bidirectional signal lines (e.g., RS-485, CAN) require protection. | Choose only if line polarity reverses or differential signaling demands symmetrical clamping. |
Compared with SMA5J5.0AHE3/5A, the E3 version lacks automotive qualification but offers identical surge performance at lower cost, while the CA variant provides bidirectional clamping essential for AC or differential interfaces-neither is pin-compatible without circuit redesign due to polarity and symmetry differences.

FAQ
What is the clamping voltage of the SMA5J5.0AHE3/5A under a 10/1000 µs surge?
The SMA5J5.0AHE3/5A clamps to 54.3 V at its rated peak pulse current of 9.2 A under a 10/1000 µs waveform. This value is measured per industry-standard test conditions and reflects the maximum voltage seen by downstream components during such a transient. The SMA5J5.0AHE3/5A maintains this clamping performance across its specified operating temperature range when mounted on recommended 5.0 mm × 5.0 mm copper pads.
Is the SMA5J5.0AHE3/5A suitable for automotive applications?
Yes, the SMA5J5.0AHE3/5A is AEC-Q101 qualified and explicitly designated for automotive use via the "HE3" suffix. It meets requirements for temperature cycling, mechanical shock, and humidity resistance, and is commonly deployed in body control modules, infotainment power supplies, and sensor interfaces. The SMA5J5.0AHE3/5A also complies with RoHS and is halogen-free, supporting modern automotive material compliance standards.
How does the SMA5J5.0AHE3/5A differ from the SMA5J5.0A-E3/5A?
The SMA5J5.0AHE3/5A includes AEC-Q101 qualification and is rated for automotive-grade reliability, whereas the SMA5J5.0A-E3/5A is commercial-grade only. Electrically and physically, both share identical VWM (5.0 V), VBR (6.4–7.07 V), PPPM (500 W), and SMA (DO-214AC) packaging. The SMA5J5.0AHE3/5A is preferred for production automotive systems; the E3 version suits cost-sensitive industrial or consumer designs where qualification is not mandated.
What is the maximum junction temperature rating for the SMA5J5.0AHE3/5A?
The SMA5J5.0AHE3/5A has a maximum junction temperature (TJ) of +150 °C, enabling reliable operation in under-hood automotive environments and enclosed industrial equipment. Derating curves in the datasheet show that peak pulse power decreases linearly above 25 °C ambient, with full 500 W capability maintained only at TA ≤ 25 °C. The SMA5J5.0AHE3/5A's RθJA of 80 °C/W informs heatsinking requirements for sustained surge duty cycles.
Does the SMA5J5.0AHE3/5A have polarity marking, and how is it oriented?
Yes, the SMA5J5.0AHE3/5A is unidirectional and marked with a cathode band (black stripe) on the SMA (DO-214AC) package body. The banded end is the cathode and must be connected to the line being protected (e.g., 5 V rail), while the unmarked end is the anode and connects to ground. Incorrect orientation prevents proper clamping and may cause catastrophic failure during overvoltage events. The SMA5J5.0AHE3/5A's polarity is defined per JEDEC DO-214AC standard and verified in Vishay's mechanical drawings.
