Product details
Overview
1N6284AHE3_A/C from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary-side overvoltage protection in power rails and signal lines. It features a 34.2 V to 37.8 V breakdown voltage (VBR) at 1.0 mA, 30.8 V maximum standoff voltage (VWM), 49.9 V clamping voltage (VC) at 30.1 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces against lightning-induced transients and inductive switching surges.
For engineers reviewing the 1N6284AHE3_A/C datasheet, 1N6284AHE3_A/C pinout, 1N6284AHE3_A/C application, or 1N6284AHE3_A/C equivalent, this part delivers verified AEC-Q101 qualification (HE3 suffix), RoHS-compliant matte tin-plated leads, UL 94 V-0 molded epoxy package, and validated clamping performance for automotive body electronics, industrial PLC I/O modules, telecom line cards, and DC power input stages requiring robust 1.5 kW surge immunity.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector, activating when transient voltage exceeds its VWM of 30.8 V and clamping to ≤49.9 V at 30.1 A. Its glass-passivated junction enables sub-nanosecond response time and low incremental surge resistance, critical for protecting fast-switching MOSFET gates and microcontroller I/O pins.
The device complies with JEDEC standards for transient suppression, supports 200 A non-repetitive forward surge current (IFSM), and maintains stable operation across -55 °C to +175 °C junction temperature range - enabling deployment in under-hood automotive environments and high-temperature industrial enclosures without derating penalties beyond 25 °C ambient.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A-E3/52 | DO-214AA package (SMB), 36 V VWM, 58.1 V VC @ 25.4 A, 600 W PPPM | Lower power rating and higher clamping voltage; suited for space-constrained PCBs with lower surge exposure | Select when board area is limited and system-level surge testing does not exceed IEC 61000-4-5 Level 2 |
| 1.5KE36AHE3_A/C | Same electrical specs and AEC-Q101 qualification; identical 1.5KE package but different base ordering code | No functional or application difference - alternate manufacturer-marked variant of same die and assembly | Use interchangeably where procurement logistics favor Vishay's 1.5KE prefix over 1N62xx numbering |
Compared with SMBJ36A-E3/52, the 1N6284AHE3_A/C offers 2.5× higher peak pulse power and 9.2 V lower clamping voltage at rated current - critical for protecting 3.3 V/5 V logic supplies. Versus 1.5KE36AHE3_A/C, it shares identical performance but differs only in JEDEC-standardized part numbering convention, with no design impact.

FAQ
What is the breakdown voltage range of the 1N6284AHE3_A/C?
The 1N6284AHE3_A/C has a guaranteed breakdown voltage (VBR) range of 34.2 V to 37.8 V at a test current of 1.0 mA, measured per JEDEC standard. This tight tolerance ensures consistent clamping behavior across production lots and supports precise coordination with downstream overvoltage protection thresholds in power management ICs.
Is the 1N6284AHE3_A/C suitable for automotive applications?
Yes, the 1N6284AHE3_A/C carries the HE3 suffix indicating AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It is explicitly rated for automotive use in body electronics, power distribution units, and infotainment power supplies - validated for operation from -55 °C to +175 °C and compliant with load dump and ISO 7637-2 pulse requirements when properly mounted.
How does the clamping voltage of the 1N6284AHE3_A/C compare to similar 36 V TVS diodes?
The 1N6284AHE3_A/C clamps to 49.9 V at its rated 30.1 A peak pulse current (10/1000 µs), which is 8.2 V lower than the SMBJ36A-E3/52 (58.1 V). This lower VC directly reduces stress on protected ICs and extends safe operating area - especially critical for 3.3 V or 5 V logic interfaces sharing the same rail.
What is the meaning of the "A/C" suffix in 1N6284AHE3_A/C?
The "A/C" suffix in 1N6284AHE3_A/C denotes Vishay's internal revision coding: "A" indicates the first revision of the HE3-qualified 1N6284A die and assembly, while "C" specifies the preferred packaging code (13" paper tape and reel, 1400 pcs per reel). It does not indicate polarity or bidirectionality - the part remains unidirectional per its 1N6284A designation.
Can the 1N6284AHE3_A/C be used in parallel for higher surge current handling?
Yes, the 1N6284AHE3_A/C can be paralleled to increase total peak pulse current capacity, provided matched units are used and layout symmetry minimizes current imbalance. However, derating by ≥20% per device is recommended due to VBR tolerance spread (±5%), and thermal coupling must be managed to avoid localized overheating during repetitive surges.
