Product details
Overview
1N6267-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary-side overvoltage protection in DC power rails and signal lines. It features a 6.45 V to 7.14 V breakdown voltage (VBR) at 10 mA, 5.80 V maximum stand-off voltage (VWM), 1000 µA maximum reverse leakage at VWM, and clamps transients to ≤10.5 V at 143 A peak pulse current (IPPM) under 10/1000 µs waveform - used in automotive body control modules and industrial sensor interfaces.
For engineers reviewing the 1N6267-E3/54 datasheet, 1N6267-E3/54 pinout, 1N6267-E3/54 application, or 1N6267-E3/54 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, clamping performance data, thermal derating curves, and direct alternatives for surge protection design validation.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, optimized for fast transient response (<1 ns) and low incremental surge resistance. Its unidirectional polarity uses a cathode band marking, and it complies with JEDEC standard 1.5KE case outline for through-hole mounting.
The 1N6267-E3/54 delivers 1500 W peak pulse power (10/1000 µs), 6.5 W steady-state power dissipation at TL = 75 °C, and supports 200 A non-repetitive forward surge current (8.3 ms half-sine). Junction temperature range is –55 °C to +175 °C, with thermal resistance RθJA = 75 °C/W and RθJL = 15.4 °C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.45 V / 7.14 V at IT = 10 mA - defines precise avalanche initiation threshold for reliable overvoltage triggering |

Applications
| Automotive Body Control Module | Industrial PLC Input Protection |
|---|---|
Use Scenario: Protects microcontroller I/O pins and CAN transceiver power rails from load dump and alternator ripple in 12 V vehicle systems. IC Role / Device Role: Primary clamping element placed between battery feed and LDO input, shunting surge energy to chassis ground. Use Value: Limits transient voltage to ≤10.5 V, preventing latch-up or gate oxide rupture in 5 V/3.3 V logic devices downstream. | Use Scenario: Shields 24 V digital input terminals of programmable logic controllers from field-wiring induced surges and relay coil flyback. IC Role / Device Role: Standoff protector mounted across input optocoupler supply, conducting only during >5.8 V transients. Use Value: Maintains system uptime by absorbing 1500 W pulses without failure, eliminating need for redundant fusing or resettable PTCs. |
| Consumer Appliance Motor Drive | Telecom Power Supply Input |
Use Scenario: Installed across brushless DC motor driver FET source-drain nodes to suppress back-EMF spikes during commutation. IC Role / Device Role: Unidirectional TVS connected anode-to-source, cathode-to-drain, clamping negative-going transients.

IC Role / Device Role: First-line transient suppressor on 300–400 V DC bus, rated for 1500 W single-event energy absorption. Use Value: Enables compliance with IEC 61000-4-5 Level 3 (2 kV line-earth) without additional MOV staging or snubber networks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.8A | Surface-mount SMB package (vs. axial 1.5KE); same VBR range but lower PPPM = 600 W | Used where board space is constrained and surge energy is ≤600 W; not suitable for 1500 W load-dump scenarios | Select when automated SMT assembly is required and peak surge duty is moderate (e.g., USB port protection) |
| 1.5KE6.8A | Identical electrical specs and JEDEC 1.5KE package; differs only in part numbering convention and tape/reel packaging (E3/54 vs. standard bulk) | No functional difference; both rated for same 1500 W, 143 A, 10.5 V clamping performance | Direct form-fit-function replacement; use 1.5KE6.8A when alternate packaging or distributor stock availability is preferred |
Compared with SMBJ6.8A, the 1N6267-E3/54 provides 2.5× higher surge power handling and axial-lead robustness for high-vibration environments; compared with 1.5KE6.8A, it shares identical protection characteristics but ships in 13" paper tape (54 mm reel width) for optimized pick-and-place compatibility.

FAQ
What is the breakdown voltage tolerance of the 1N6267-E3/54?
The 1N6267-E3/54 has a specified breakdown voltage (VBR) range of 6.45 V to 7.14 V at test current IT = 10 mA, yielding ±5% tolerance around the nominal 6.8 V rating. This tight distribution ensures consistent clamping behavior across production lots and supports deterministic overvoltage margining in safety-critical designs.
Does the 1N6267-E3/54 meet automotive qualification standards?
The 1N6267-E3/54 is commercial-grade and not AEC-Q101 qualified; however, its companion variant 1.5KE6.8AHE3_B is AEC-Q101 certified. The 1N6267-E3/54 shares identical electrical and thermal specs but lacks the extended reliability testing required for automotive under-hood deployment per AEC-Q101.
What is the maximum clamping voltage of the 1N6267-E3/54 at rated peak pulse current?
The 1N6267-E3/54 clamps to a maximum of 10.5 V at its rated peak pulse current of 143 A (10/1000 µs waveform). This value is guaranteed per Vishay's datasheet and reflects worst-case VC under standardized surge conditions, enabling accurate downstream voltage margin analysis.
Can the 1N6267-E3/54 be used in bidirectional configurations?
No - the 1N6267-E3/54 is strictly unidirectional. Bidirectional variants carry the "CA" suffix (e.g., 1.5KE6.8CA). Using the 1N6267-E3/54 in reverse-biased mode beyond its 5.80 V stand-off voltage risks premature conduction and unreliable clamping; always verify polarity during PCB layout.
What is the lead finish and solderability specification for the 1N6267-E3/54?
The 1N6267-E3/54 features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. It withstands solder dip at 275 °C for up to 10 seconds (per JESD 22-B106) and meets JESD 201 Class 1A whisker resistance, ensuring reliable through-hole reflow and wave solder joint integrity.
