Product details
Overview
1N6282A-E3/54 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 30 V breakdown voltage (VBR = 28.5–31.5 V at 1.0 mA), 25.6 V standoff voltage (VWM), 41.4 V clamping voltage (VC) at 36.2 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 1N6282A-E3/54 datasheet, 1N6282A-E3/54 pinout, 1N6282A-E3/54 application, or 1N6282A-E3/54 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, clamping performance under standardized surge conditions, thermal derating behavior, and direct alternatives for circuit protection design-in.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR, it avalanches rapidly (<1 ns response) to divert transient energy away from downstream components. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at VWM), while the molded epoxy case meets UL 94 V-0 flammability rating.
Thermal performance is defined by RθJA = 75 °C/W and RθJL = 15.4 °C/W, enabling reliable operation up to TJ = 175 °C. Power dissipation is rated at 6.5 W on infinite heatsink at TL = 75 °C, with surge capability of 200 A (8.3 ms half-sine, unidirectional only).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 28.5 V / 31.5 V at 1.0 mA - defines precise avalanche initiation threshold for repeatable clamping onset |
| VWM | 25.6 V - maximum continuous reverse operating voltage before leakage rises significantly |
| VC @ IPPM | 41.4 V at 36.2 A - clamped voltage during 10/1000 µs surge, limiting stress on protected ICs |
| PPPM | 1500 W - peak transient power handling capacity under standardized surge waveform |
| IFSM | 200 A - non-repetitive forward surge current rating, critical for input rectifier-stage protection |
| TJ max. | 175 °C - maximum junction temperature, supporting high-ambient industrial and automotive environments |
| Leakage @ VWM | <1.0 µA - ensures minimal standby power loss and signal integrity in low-current circuits |
Pinout & Package
Package: JEDEC DO-201AD (Case Style 1.5KE), axial-leaded, molded epoxy body with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional clamp configuration |
| Cathode | Avalanche conduction terminal | Connected to protected line (e.g., +12 V rail); color band identifies this end for correct PCB orientation |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30A | DO-214AA package (smaller footprint), 30 V VBR, 48.4 V VC @ 31.8 A, 600 W PPPM | Lower peak power rating; suited for space-constrained consumer designs with moderate surge exposure | Select SMBJ30A when board area is limited and surge threat level is below IEC 61000-4-5 Level 3 |
| 1.5KE30A-E3/54 | Same electrical specs and JEDEC 1.5KE package; identical VBR, VC, and PPPM; differs only in part numbering convention (manufacturer cross-reference) | No functional difference; fully interchangeable in layout and performance | Choose 1.5KE30A-E3/54 if sourcing through distributors listing the 1.5KE prefix as primary SKU |
Compared with SMBJ30A, 1N6282A-E3/54 delivers 2.5× higher surge power handling and tighter clamping (41.4 V vs. 48.4 V), making it preferable for industrial-grade reliability; versus 1.5KE30A-E3/54, it is electrically and mechanically identical - differing only in legacy part-numbering lineage.

FAQ
What is the breakdown voltage range of the 1N6282A-E3/54?
The 1N6282A-E3/54 has a guaranteed breakdown voltage (VBR) range of 28.5 V to 31.5 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 reliable design margins for 24 V and 30 V system protection. The 1N6282A-E3/54 maintains this specification across its full operating temperature range of –55 °C to +175 °C.
Is the 1N6282A-E3/54 RoHS compliant and lead-free?
Yes, the 1N6282A-E3/54 carries the "E3" suffix, indicating full RoHS compliance and lead-free construction per EU Directive 2011/65/EU. Its matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability requirements, and it passes JESD 201 Class 1A whisker testing. The 1N6282A-E3/54 is certified for commercial-grade applications and does not carry AEC-Q101 qualification.
How does the clamping voltage of the 1N6282A-E3/54 compare to its breakdown voltage?
The 1N6282A-E3/54 clamps at 41.4 V when subjected to its rated peak pulse current of 36.2 A (10/1000 µs waveform), resulting in a clamping ratio (VC/VBR) of approximately 1.42. This ratio reflects efficient avalanche conduction and is critical for ensuring protected ICs remain below their absolute maximum voltage ratings. The 1N6282A-E3/54 achieves this performance with low incremental surge resistance and fast sub-nanosecond response.
Can the 1N6282A-E3/54 be used in bidirectional configurations?
No, the 1N6282A-E3/54 is a unidirectional TVS diode, identifiable by its cathode band marking. Bidirectional variants in the same family use the "CA" suffix (e.g., 1N6282CA). Using the 1N6282A-E3/54 in reverse-biased AC applications would result in forward conduction during one half-cycle, causing failure. For bidirectional protection at ~30 V, specify 1N6282CA-E3/54 instead.
What is the thermal resistance and power derating behavior of the 1N6282A-E3/54?
The 1N6282A-E3/54 has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead resistance (RθJL) of 15.4 °C/W. Its 6.5 W steady-state power dissipation is rated at TL = 75 °C on an infinite heatsink; above this lead temperature, power must be linearly derated per Figure 5 in the Vishay datasheet 88301. The 1N6282A-E3/54 sustains full 1500 W surge capability only at TA ≤ 25 °C, with progressive reduction above that ambient.
