Product details
Overview
1N6293A-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 77.9 V to 86.1 V breakdown voltage (VBR), 70.1 V standoff voltage (VWM), 113 V clamping voltage at 13.3 A peak pulse current, 1500 W peak pulse power (10/1000 µs), and operates across -55 °C to +175 °C junction temperature range - used in automotive power supply input stages and industrial sensor interface protection.
For engineers reviewing the 1N6293A-E3/54 datasheet, 1N6293A-E3/54 pinout, 1N6293A-E3/54 application, or 1N6293A-E3/54 equivalent, this page delivers verified electrical parameters, thermal derating behavior, clamping performance under surge conditions, RoHS-compliant packaging details, and direct alternatives for ESD/lightning transient suppression in 24 V and 48 V systems.
Technical Context
This device implements a glass-passivated silicon PN junction optimized for fast (<1 ns) response to transients and low incremental surge resistance. Its unidirectional polarity enables cathode-grounded configuration for DC rail protection, with clamping action defined by avalanche breakdown characteristics rather than Zener conduction.
The 1N6293A-E3/54 adheres to JEDEC-standard 1.5KE case style, rated for 200 A non-repetitive forward surge (8.3 ms half-sine), and exhibits 0.105 %/°C temperature coefficient of VBR. Thermal resistance is 15.4 °C/W junction-to-lead, enabling reliable operation without heatsinking up to 6.5 W continuous dissipation at TL = 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 77.9 V / 86.1 V at 1.0 mA test current - defines minimum guaranteed avalanche initiation threshold and maximum variation across production lot |
| VWM | 70.1 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA; sets safe DC bias margin below breakdown |
| VC @ IPPM | 113 V at 13.3 A - clamped voltage during 10/1000 µs surge; determines protected circuit's maximum transient exposure level |
| PPPM | 1500 W - peak pulse power handling capability; supports lightning surge immunity per IEC 61000-4-5 Level 4 (4 kV) |
| TJ max | +175 °C - maximum junction temperature; enables use in under-hood automotive environments and high-ambient industrial enclosures |
| RθJL | 15.4 °C/W - junction-to-lead thermal resistance; confirms suitability for PCB-mount without external heatsink in moderate-power applications |
| IFSM | 200 A - peak forward surge rating (8.3 ms half-sine); validates robustness against inductive kickback in relay or solenoid drive circuits |
Pinout & Package
Package: Case Style 1.5KE - molded epoxy body with matte tin-plated leads, UL 94 V-0 rated, RoHS compliant (E3 suffix), 0.375" lead length standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / transient return path | Connected to protected line (e.g., 24 V rail); conducts during positive surges when cathode is grounded |
| Cathode | Reference node / clamping reference | Typically tied to system ground; establishes fixed reference for avalanche clamping action and defines unidirectional polarity |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable long-term leakage performance and resistance to humidity-induced degradation in harsh environments |
| 1500 W peak pulse power (10/1000 µs) | Supports EN 61000-4-5 surge immunity testing up to 4 kV open-circuit voltage in 2 Ω source impedance configurations |
| 0.105 %/°C VBR tempco | Minimizes drift in clamping threshold across automotive (-40 °C to +125 °C ambient) and industrial temperature ranges |
| 1.0 µA max reverse leakage @ VWM | Prevents excessive standby power loss in battery-backed or energy-sensitive systems such as remote sensors |
| Solder dip rated 275 °C for 10 s | Confirms compatibility with standard lead-free reflow and wave soldering processes without parametric shift or delamination |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |

FAQ
What is the breakdown voltage tolerance for 1N6293A-E3/54?
The 1N6293A-E3/54 has a specified breakdown voltage range of 77.9 V to 86.1 V at 1.0 mA test current, representing ±5.3% tolerance about the nominal 82 V rating. This tolerance is guaranteed per JEDEC standard test conditions and applies across the full operating temperature range of -55 °C to +175 °C.
Is 1N6293A-E3/54 RoHS compliant and lead-free?
Yes, the 1N6293A-E3/54 carries the E3 suffix, indicating full RoHS compliance per Directive 2011/65/EU and exemption 6(c)-IV. The matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability standards, and the device passes JESD 201 Class 1A whisker testing.
Can 1N6293A-E3/54 be used in bidirectional configurations?
No - the 1N6293A-E3/54 is strictly unidirectional. Bidirectional variants in the same family carry the "CA" suffix (e.g., 1.5KE82CA). Using 1N6293A-E3/54 in reverse-biased AC applications would result in forward conduction and potential failure; always verify polarity marking (cathode band) during placement.
What is the maximum clamping voltage of 1N6293A-E3/54 under surge conditions?
The maximum clamping voltage (VC) of 1N6293A-E3/54 is 113 V, measured at the peak pulse current (IPPM) of 13.3 A using the standard 10/1000 µs waveform. This value is guaranteed per datasheet Table 1 and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Does 1N6293A-E3/54 require a heatsink for continuous operation?
No heatsink is required for continuous operation at ambient temperatures ≤75 °C, as the 1N6293A-E3/54 dissipates up to 6.5 W with lead temperature (TL) held at 75 °C. Its 15.4 °C/W junction-to-lead thermal resistance allows direct PCB mounting with adequate copper pour; heatsinking becomes necessary only above 75 °C ambient or under sustained >6.5 W power dissipation.
