Product details
Overview
SMCJ5.0AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients up to 1500 W peak pulse power with 9.2 V maximum clamping voltage at 163 A peak pulse current, 5.0 V stand-off voltage, and 6.4–7.07 V breakdown voltage range at 10 mA test current. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the SMCJ5.0AHE3_A/I datasheet, SMCJ5.0AHE3_A/I pinout, SMCJ5.0AHE3_A/I application, or SMCJ5.0AHE3_A/I equivalent, key selection criteria include its AEC-Q101 qualification, 1500 W 10/1000 µs surge rating, low 9.2 V clamping voltage at rated IPPM, RoHS-compliant matte tin-plated leads, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This device operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology for stable breakdown behavior and fast response (<1 ns) to ESD and lightning-induced transients. Its thermal resistance is 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-lead), enabling reliable operation up to 150 °C junction temperature under defined PCB layout conditions.
The SMCJ5.0AHE3_A/I exhibits 1000 µA maximum reverse leakage at 5.0 V stand-off voltage and a positive temperature coefficient of breakdown voltage (+0.057 %/°C), ensuring predictable voltage drift across temperature. It meets J-STD-020 MSL Level 1 and JESD201 Class 2 whisker resistance requirements.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Use Scenario: Guarding −48 V telecom power inputs against lightning-induced surges in remote radio units and base station equipment. IC Role / Device Role / Timing Role: Secondary-level TVS used in conjunction with GDTs or MOVs to refine clamping voltage and handle residual fast-rising transients. Use Value: Low incremental surge resistance enables effective energy sharing with upstream protectors without thermal runaway. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC5.0 | Lower PPPM (600 W), higher VC (13.4 V at 30 A), same SMC package and VWM | Not suitable for high-energy surge environments requiring 1500 W rating or sub-10 V clamping | Select SMCJ5.0AHE3_A/I when full IEC 61000-4-5 Level 4 compliance or automotive load dump protection is required |
| SMCJ5.0A-E3/57T | Identical electrical specs and AEC-Q101 qualification; differs only in packaging (7" reel, 850 pcs vs. 13" reel, 3500 pcs) | No functional difference; identical use cases and board-level performance | Choose SMCJ5.0AHE3_A/I for high-volume production requiring larger reels and optimized logistics |
Compared with SAC5.0, the SMCJ5.0AHE3_A/I delivers 2.5× higher surge power handling and 4.2 V lower clamping voltage, enabling tighter protection margins. Against SMCJ5.0A-E3/57T, it offers identical protection performance but supports scalable procurement via 3500-piece tape-and-reel format.

FAQ
What is the clamping voltage of the SMCJ5.0AHE3_A/I at its rated peak pulse current?
The SMCJ5.0AHE3_A/I has a maximum clamping voltage (VC) of 9.2 V at its rated peak pulse current (IPPM) of 163 A under 10/1000 µs waveform conditions. This value is measured with the device mounted on 0.31" × 0.31" copper pads per Vishay's recommended layout, and defines the upper voltage limit imposed on protected circuits during worst-case surge events. The SMCJ5.0AHE3_A/I maintains this clamping performance across its qualified temperature range.
Is the SMCJ5.0AHE3_A/I suitable for automotive applications?
Yes, the SMCJ5.0AHE3_A/I is AEC-Q101 qualified and explicitly designated for automotive use with ordering code suffix HE3. It undergoes rigorous stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD verification per JESD22-A114. Its 1500 W surge rating and 9.2 V clamping voltage make the SMCJ5.0AHE3_A/I appropriate for protecting engine control units, body control modules, and ADAS sensor interfaces against load dump and ISO 7637-2 transients.
How does the SMCJ5.0AHE3_A/I differ from the bidirectional SMCJ5.0CA variant?
The SMCJ5.0AHE3_A/I is unidirectional with cathode band marking and conducts only in reverse breakdown, while the SMCJ5.0CA is bidirectional with no polarity marking and clamps symmetrically in both directions. The SMCJ5.0AHE3_A/I has VBR = 6.40–7.07 V and VC = 9.2 V, whereas SMCJ5.0CA specifies VBR ≤ 7.25 V and VC ≤ 9.8 V. Use the SMCJ5.0AHE3_A/I for DC rail protection where polarity is fixed; choose SMCJ5.0CA only for AC-coupled or floating signal lines.
What is the thermal resistance of the SMCJ5.0AHE3_A/I and how does it affect PCB layout?
The SMCJ5.0AHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead resistance (RθJL) of 15 °C/W, both measured on the specified 8.0 mm × 8.0 mm copper pad layout. To maintain safe junction temperatures below 150 °C during repeated surges, PCB layout must replicate these pad dimensions and ensure adequate copper area for heat spreading. Reducing pad size increases RθJA and risks thermal failure during sustained transient activity.
Does the SMCJ5.0AHE3_A/I meet RoHS and halogen-free requirements?
Yes, the SMCJ5.0AHE3_A/I is RoHS-compliant per EU Directive 2011/65/EU and carries the HE3 suffix indicating AEC-Q101 qualification and RoHS compliance. It is not halogen-free - that designation applies to HM3-suffixed variants. The SMCJ5.0AHE3_A/I uses matte tin-plated leads and molding compound meeting UL 94 V-0 flammability rating, and complies with JESD201 Class 2 whisker resistance requirements for long-term reliability.
