Product details
Overview
SMCJ5.0AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for robust overvoltage protection of 5.0 V DC power rails and signal lines. It delivers 1500 W peak pulse power (10/1000 µs), clamps at ≤9.2 V under 163 A surge current, and features 6.40–7.07 V breakdown voltage at 10 mA test current with ±0.057 %/°C temperature coefficient.
For engineers reviewing the SMCJ5.0AHE3_A/H datasheet, SMCJ5.0AHE3_A/H pinout, SMCJ5.0AHE3_A/H application, or SMCJ5.0AHE3_A/H equivalent, key selection criteria include its AEC-Q101 qualification, 1000 µA maximum reverse leakage at 5.0 V stand-off, low 15 °C/W junction-to-lead thermal resistance, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-banded polarity, leveraging glass-passivated silicon junction technology for fast response (<1 ns) and stable clamping under repetitive transients. Its 1500 W PPPM rating is specified per standard 10/1000 µs waveform, derated linearly above 25 °C ambient per Fig. 2 in the datasheet.
The device is rated for -55 °C to +150 °C operating junction temperature, meets MSL Level 1 per J-STD-020 (260 °C peak reflow), and uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Its 75 °C/W junction-to-ambient thermal resistance assumes minimum recommended pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 µs) | 1500 W - sustains high-energy ESD and lightning-induced surges without failure |
| Stand-off Voltage (VWM) | 5.0 V - reliably blocks normal 5 V rail operation while remaining inactive |
| Breakdown Voltage (VBR) | 6.40–7.07 V at 10 mA - ensures precise triggering just above nominal supply |
| Clamping Voltage (VC) | ≤9.2 V at 163 A - limits downstream IC voltage stress during worst-case surge |
| Reverse Leakage (ID) | ≤1000 µA at 5.0 V - minimizes quiescent power loss in battery-powered systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC5.0 | Lower 500 W PPPM rating; 10.5 V clamping at 48 A; SOD-123FL package (smaller footprint) | Targeted at space-constrained consumer electronics with lower surge threat levels | Select SAC5.0 only when system-level surge testing confirms ≤500 W requirement and PCB layout cannot accommodate SMC outline |
| SMCJ5.0A-E3/57T | Identical electrical specs and SMC package; differs only in tape-and-reel packaging (57T = 7" reel, 850 pcs) vs. H-code (same reel size but distinct ordering variant) | No functional difference; both meet AEC-Q101 and same thermal derating curves | SMCJ5.0A-E3/57T is functionally interchangeable but requires verification of distributor-specific traceability and lot documentation alignment |
Compared with SAC5.0, SMCJ5.0AHE3_A/H provides 3× higher surge energy handling and superior thermal dissipation via larger SMC package; compared with SMCJ5.0A-E3/57T, it shares identical protection performance but offers distinct logistics tracking under Vishay's HE3 automotive-grade ordering nomenclature.

FAQ
What is the clamping voltage of SMCJ5.0AHE3_A/H at its rated peak pulse current?
The SMCJ5.0AHE3_A/H has a maximum clamping voltage (VC) of 9.2 V when subjected to its rated peak pulse current of 163 A under the standard 10/1000 µs waveform. This value is measured at the device terminals with specified mounting conditions (0.31" × 0.31" copper pads), and ensures downstream 5 V logic components remain within safe operating voltage limits during surge events. The SMCJ5.0AHE3_A/H maintains this clamping performance across its qualified temperature range.
Is SMCJ5.0AHE3_A/H suitable for automotive applications?
Yes, SMCJ5.0AHE3_A/H is explicitly AEC-Q101 qualified, as confirmed by its HE3 suffix and Vishay documentation. It is designed for automotive environments including body electronics, infotainment power supplies, and sensor interfaces where compliance with load dump, jump start, and ESD immunity standards is required. The SMCJ5.0AHE3_A/H undergoes stress testing per AEC-Q101 including HTGB, TCT, and UHAST to validate reliability under automotive thermal and humidity conditions.
How does the SMCJ5.0AHE3_A/H differ from bidirectional variants like SMCJ5.0CA?
The SMCJ5.0AHE3_A/H is unidirectional, meaning it conducts only in reverse bias during overvoltage events and has a defined cathode band; SMCJ5.0CA is bidirectional with symmetrical clamping in both polarities and no polarity marking. Electrically, SMCJ5.0AHE3_A/H has VBR = 6.40–7.07 V and VC ≤ 9.2 V, while SMCJ5.0CA exhibits matched breakdown in both directions but slightly higher clamping (e.g., 7.25 V max VBR). The SMCJ5.0AHE3_A/H is selected for DC rail protection where polarity is fixed, unlike AC or data-line applications requiring bidirectional symmetry.
What is the thermal resistance profile of SMCJ5.0AHE3_A/H?
The SMCJ5.0AHE3_A/H has a typical junction-to-lead thermal resistance (RθJL) of 15 °C/W and junction-to-ambient resistance (RθJA) of 75 °C/W under standard mounting conditions (0.31" × 0.31" copper pads). This enables effective heat dissipation during repetitive surge events and supports continuous operation up to +150 °C junction temperature. The low RθJL value allows efficient thermal transfer to PCB copper, making the SMCJ5.0AHE3_A/H suitable for high-duty-cycle protection schemes when layout guidelines are followed.
Can SMCJ5.0AHE3_A/H be used in place of older SMAJ5.0A devices?
No, SMCJ5.0AHE3_A/H is not a drop-in replacement for SMAJ5.0A due to package and thermal differences: SMAJ uses DO-214AC (SMA) with higher RθJA (~100 °C/W), while SMCJ5.0AHE3_A/H uses larger DO-214AB (SMC) with lower RθJA (75 °C/W) and higher PPPM (1500 W vs. 400 W). Substituting requires PCB pad redesign and thermal validation. The SMCJ5.0AHE3_A/H offers superior surge capability but demands revised layout-direct replacement is not supported without engineering review.
