Product details
Overview
SMA5J5.0AHE3_A/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for primary overvoltage protection of sensitive electronics. 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 surge current, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMA5J5.0AHE3_A/I datasheet, SMA5J5.0AHE3_A/I pinout, SMA5J5.0AHE3_A/I application, or SMA5J5.0AHE3_A/I equivalent, key selection criteria include clamping performance under 10/1000 µs transients, junction temperature derating above 25 °C, unidirectional polarity with cathode band marking, 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, activating when reverse voltage exceeds its VBR threshold to divert surge energy away from downstream ICs or MOSFETs. Its glass-passivated junction ensures stable leakage (<800 µA at VWM) and fast response time (<1 ns), critical for protecting signal lines against ESD and inductive switching transients.
The device is rated for -55 °C to +150 °C operating junction temperature, with thermal resistance RθJA = 80 °C/W and RθJL = 25 °C/W. Its 500 W peak pulse power rating applies only under specified 10/1000 µs waveform conditions and derates linearly above TA = 25 °C per manufacturer curve Fig. 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin below circuit supply rails. |
| VBR min/max | 6.4 V / 7.07 V at 10 mA - Confirmed breakdown range ensuring reliable turn-on during transients without premature conduction. |
| VC @ IPPM | 54.3 V at 9.2 A - Clamping voltage under full-rated 10/1000 µs surge; determines maximum stress imposed on protected components. |
| PPPM | 500 W - Peak pulse power handling capability; defines survivability against standardized lightning/surge waveforms. |
| TJ max | +150 °C - Maximum junction temperature; sets thermal design limits for PCB pad layout and ambient operating conditions. |
| Polarity | Unidirectional - Cathode band marked; enables DC-biased protection paths while blocking forward conduction in normal operation. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Molding compound meets UL 94 V-0. Polarity indicated by cathode band on unidirectional types.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected circuit; carries surge current during clamping. |
| Cathode | Reverse-biased clamping terminal | Marked with band; connected to higher-potential rail (e.g., VCC); initiates avalanche conduction when VREV > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance per JEDEC standards. |
| Glass passivated junction | Ensures stable VBR tolerance and low leakage drift across temperature and lifetime, critical for long-term protection integrity. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients, improving clamping precision for sub-100 ns events. |
| MSL Level 1 (260 °C) | Enables standard lead-free reflow without moisture sensitivity concerns; no bake required prior to assembly. |

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-E3/61 | Same electrical specs and SMA package; RoHS-compliant commercial grade without AEC-Q101 qualification. | Lacks automotive qualification; suitable for consumer/industrial but not automotive OEM designs requiring PPAP documentation. | Select SMA5J5.0AHE3_A/I when AEC-Q101 compliance, traceable lot control, and extended temperature validation are mandatory. |
| SMA6J5.0AHE3_A/I | 600 W peak pulse power (vs. 500 W), identical VWM/VBR/VC, same AEC-Q101 qualification and SMA package. | Higher energy handling enables longer surge duration tolerance; requires verification of PCB thermal relief and pad layout compatibility. | Choose SMA6J5.0AHE3_A/I where system-level surge testing exceeds IEC 61000-4-5 Level 4 (4 kV line-to-line) requirements. |
Compared with SMA5J5.0A-E3/61, SMA5J5.0AHE3_A/I adds AEC-Q101 validation and tighter process controls for automotive use; compared with SMA6J5.0AHE3_A/I, it trades 100 W lower PPPM for potentially better cost and footprint efficiency in less demanding surge environments.

FAQ
What is the clamping voltage of the SMA5J5.0AHE3_A/I under its rated surge current?
The SMA5J5.0AHE3_A/I has a maximum clamping voltage (VC) of 54.3 V at its rated peak pulse current (IPPM) of 9.2 A, measured using the standardized 10/1000 µs double-exponential waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during transient events. The SMA5J5.0AHE3_A/I maintains this clamping performance due to its low incremental surge resistance and optimized silicon junction design.
Is the SMA5J5.0AHE3_A/I suitable for automotive applications?
Yes, the SMA5J5.0AHE3_A/I is AEC-Q101 qualified and explicitly designated for automotive use, with ordering code suffix HE3 indicating RoHS-compliant and AEC-Q101 validated construction. It undergoes rigorous stress testing including temperature cycling, high-temperature reverse bias, and surge endurance per JEDEC standards. The SMA5J5.0AHE3_A/I is commonly deployed in engine control units, body electronics, and ADAS power supplies where reliability under harsh thermal and electrical conditions is mandatory.
What does the "_A/I" suffix mean in SMA5J5.0AHE3_A/I?
The "_A/I" suffix in SMA5J5.0AHE3_A/I indicates two specific attributes: "A" denotes the revision level of the device's internal design or test specification, and "I" specifies the packaging format - in this case, 7500 units per 13-inch diameter plastic tape and reel. This matches Vishay's documented ordering information where "I" corresponds to the 13″ reel option, distinct from "H" used for 7″ reels. The SMA5J5.0AHE3_A/I is fully compatible with standard SMT pick-and-place equipment calibrated for DO-214AC carriers.
How does the SMA5J5.0AHE3_A/I differ from bidirectional variants like SMA5J5.0CA?
The SMA5J5.0AHE3_A/I is unidirectional, featuring a cathode band for polarity-sensitive placement and conducting only in reverse avalanche mode, whereas SMA5J5.0CA is bidirectional with symmetrical clamping in both directions and no polarity marking. Electrically, SMA5J5.0AHE3_A/I has VWM = 5.0 V and VBR = 6.4–7.07 V, while SMA5J5.0CA exhibits identical standoff and breakdown but supports AC-coupled or floating-rail protection. The SMA5J5.0AHE3_A/I is selected when DC-biased protection is required, such as on positive power rails.
What is the thermal resistance of the SMA5J5.0AHE3_A/I, and how does it affect layout?
The SMA5J5.0AHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W and junction-to-lead (RθJL) of 25 °C/W, measured on 0.2″ × 0.2″ (5.0 mm × 5.0 mm) copper pads per terminal. To maintain safe junction temperatures under repeated surges, PCB layout must replicate this minimum pad area and ensure adequate copper pour connectivity. Reducing pad size increases RθJA, risking thermal runaway during high-duty-cycle transients - a critical consideration for the SMA5J5.0AHE3_A/I in automotive or industrial environments.
