Product details
Overview
1N6297A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 120 V breakdown voltage (VBR = 114–126 V at 1 mA), 102 V maximum standoff voltage (VWM), 165 V clamping voltage (VC) at 9.1 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces in industrial power supplies and automotive ECUs.
For engineers reviewing the 1N6297A-E3/54 datasheet, 1N6297A-E3/54 pinout, 1N6297A-E3/54 application, or 1N6297A-E3/54 equivalent, this part delivers verified transient suppression performance in high-reliability unidirectional DC rail protection, with RoHS-compliant matte tin-plated leads, JEDEC 1.5KE package, and AEC-Q101 qualification available in HE3 variants.
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 surge current away from downstream circuitry. Its glass-passivated junction ensures stable leakage (<1 µA at VWM) and low incremental surge resistance, critical for repeatable clamping under repetitive transients.
The device sustains 200 A non-repetitive forward surge current (8.3 ms half-sine), supports continuous power dissipation of 6.5 W on infinite heatsink, and maintains operation across –55 °C to +175 °C junction temperature range - enabling use in under-hood automotive modules and industrial motor drives where thermal margin is constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 114 V / 126 V at 1 mA - defines precise avalanche initiation threshold for reliable overvoltage detection |
| VWM | 102 V - maximum continuous reverse operating voltage before leakage rises significantly |
| VC @ IPPM | 165 V at 9.1 A - clamping voltage during 1500 W transient, limiting stress on protected ICs |
| PPPM | 1500 W - peak pulse power handling with 10/1000 µs waveform, suitable for lightning and inductive switch-off surges |
| IFSM | 200 A - single-cycle surge current capability, supporting protection against high-energy load dump events |
| TJ max. | +175 °C - extended junction temperature rating enables placement near heat sources without derating |
| RθJA | 75 °C/W - thermal resistance from junction to ambient, informs PCB copper area requirements for thermal management |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ120A | Lower PPPM (600 W), smaller SMB package (3.5 × 3.5 mm), VC = 196 V @ 3.1 A | Best suited for space-constrained PCBs with moderate surge exposure (e.g., consumer USB ports) | Select when board area is limited and peak surge energy is ≤600 W; not drop-in due to lower power and different footprint |
| 1.5KE120A | Same electrical specs and 1.5KE package; differs only in packaging suffix (E3/54 = tape-and-reel, standard commercial grade) | Identical functional behavior and mechanical fit; no design change required | Choose for identical performance with alternate reel packaging - direct form-fit-function replacement |
Compared with SMBJ120A, 1N6297A-E3/54 delivers 2.5× higher surge power handling and tighter VC margin, making it preferable for industrial and automotive front-end protection; versus 1.5KE120A, it is functionally identical but supplied in optimized tape-and-reel format for automated assembly.

FAQ
What is the breakdown voltage tolerance for 1N6297A-E3/54?
The 1N6297A-E3/54 has a specified breakdown voltage range of 114 V to 126 V at 1 mA test current, corresponding to a ±5 % tolerance around the nominal 120 V rating. This tight tolerance ensures predictable clamping onset across production lots and temperature extremes, critical for protecting voltage-sensitive loads like microcontrollers and analog sensors in the 1N6297A-E3/54 application circuit.
Is 1N6297A-E3/54 RoHS compliant and lead-free compatible?
Yes, the "E3" suffix in 1N6297A-E3/54 indicates full RoHS compliance per Directive 2011/65/EU, with matte tin-plated leads that meet J-STD-002 and JESD 22-B102 solderability standards. It withstands lead-free reflow profiles up to 260 °C and passes JESD 201 Class 1A whisker testing - confirming suitability for modern high-reliability 1N6297A-E3/54 manufacturing processes.
Can 1N6297A-E3/54 be used in bidirectional configurations?
No, 1N6297A-E3/54 is strictly a unidirectional TVS diode, identifiable by its cathode band marking. Bidirectional variants in the same family use the "CA" suffix (e.g., 1N6297CA). Using 1N6297A-E3/54 in bidirectional AC or differential signal lines would result in forward conduction during negative half-cycles, causing failure - always verify polarity alignment in the 1N6297A-E3/54 layout.
What is the maximum clamping voltage of 1N6297A-E3/54 under surge conditions?
The maximum clamping voltage (VC) of 1N6297A-E3/54 is 165 V, measured at 9.1 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value represents the upper limit of voltage seen by protected circuitry during worst-case transient events - a key parameter for validating safe operating margins in the 1N6297A-E3/54 protection network design.
Does 1N6297A-E3/54 require a heatsink for continuous operation?
No heatsink is required for 1N6297A-E3/54 under normal standby or low-duty-cycle surge conditions, as its 6.5 W steady-state power dissipation rating applies only with infinite heatsinking. In typical PCB mounting (2 oz copper, 1 in² pad), thermal limits are governed by transient energy, not continuous power. However, for repetitive surges >1 Hz, thermal simulation using RθJA = 75 °C/W is recommended to ensure 1N6297A-E3/54 junction temperature stays below 175 °C.
