Product details
Overview
1N6267-E3/73 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 stand-off voltage (VWM), 10.5 V clamping voltage (VC) at 143 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 inductive switching transients and ESD.
For engineers reviewing the 1N6267-E3/73 datasheet, 1N6267-E3/73 pinout, 1N6267-E3/73 application, or 1N6267-E3/73 equivalent, this device is selected for robust, low-clamping-voltage transient suppression in automotive body electronics, industrial PLC I/O modules, and telecom power supply front-ends where fast response (<1 ns), high surge capability, and AEC-Q101-compliant reliability are required.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction to achieve sub-nanosecond response time and low incremental surge resistance. Its clamping behavior is characterized by a 10.5 V maximum clamping voltage at 143 A IPPM under 10/1000 µs waveform, with thermal resistance of 15.4 °C/W (junction-to-lead) enabling reliable operation up to 175 °C junction temperature.
The device operates within -55 °C to +175 °C ambient range and supports 200 A non-repetitive forward surge current (IFSM) per 8.3 ms half-sine wave. Its 3.5 V forward voltage at 100 A ensures minimal conduction loss during fault conditions, while the matte tin-plated leads comply with J-STD-002 solderability and JESD 201 Class 1A whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.45 V / 7.14 V at 10 mA - defines precise voltage threshold at which clamping initiates, critical for matching system overvoltage tolerance margins |
| VWM | 5.80 V - maximum continuous reverse operating voltage before leakage exceeds 1000 µA; sets safe DC rail margin below breakdown |
| VC @ IPPM | 10.5 V at 143 A - peak clamped voltage seen by protected circuit during worst-case 1500 W transient, directly limiting stress on downstream components |
| PPPM | 1500 W - peak pulse power handling with 10/1000 µs waveform, enabling protection against lightning-induced surges and inductive kickback |
| IFSM | 200 A - non-repetitive forward surge current rating (8.3 ms half-sine), supporting robustness against accidental polarity reversal or high-energy faults |
| TJ max. | +175 °C - maximum junction temperature, allowing deployment in under-hood automotive or high-ambient industrial environments without derating |
| RθJL | 15.4 °C/W - low junction-to-lead thermal resistance, facilitating heat dissipation through PCB copper pours or chassis mounting without heatsinks |
Pinout & Package
Package: DO-201AD (Case Style 1.5KE), axial-leaded, molded epoxy body with UL 94 V-0 flammability rating; cathode indicated by color band on one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / transient return path | Connected to ground or low-impedance return plane; must be routed with minimal inductance to preserve clamping speed |
| Cathode | Protected line connection / transient sink node | Connected to the line being protected (e.g., 5 V rail, CAN_H); color band identifies this terminal |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable, repeatable breakdown characteristics over temperature and lifetime; eliminates surface contamination sensitivity |
| 1500 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-earth) when properly laid out, without external series impedance |
| Clamping voltage ≤10.5 V at 143 A | Keeps protected ICs (e.g., microcontrollers, RS-485 transceivers) safely below absolute maximum ratings during transients |
| Response time <1 ns | Acts before parasitic inductance of PCB traces can generate damaging overshoot - essential for protecting high-speed digital interfaces |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker resistance and J-STD-002 solderability, ensuring long-term reliability in automated assembly |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Card |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A | Lower PPPM (400 W), smaller SMA package (lower IPPM = 64.5 A), VC = 10.3 V at 38.9 A | Targeted for space-constrained consumer electronics; insufficient for 1500 W industrial surge standards | Select only when board area is critical and surge requirements are limited to IEC 61000-4-2 ESD or low-energy transients |
| 1.5KE6.8A-E3/54 | Identical electrical specs and DO-201AD package; differs only in tape-and-reel packaging (1400 pcs vs. 750 pcs) and reel diameter (13″ vs. 7″) | No functional difference; identical performance in all circuit roles and thermal environments | Choose 1.5KE6.8A-E3/54 for high-volume SMT production with compatible pick-and-place feeders |
Compared with SMAJ6.0A, the 1N6267-E3/73 delivers 3.75× higher surge power handling and proven suitability for automotive and industrial surge testing; compared with 1.5KE6.8A-E3/54, it offers identical protection performance but optimized for lower-volume or manual assembly via 7″ reel delivery.

FAQ
What is the breakdown voltage tolerance of the 1N6267-E3/73?
The 1N6267-E3/73 has a specified breakdown voltage range of 6.45 V to 7.14 V at 10 mA test current, representing ±5% tolerance around the nominal 6.8 V rating. This tight VBR window ensures consistent clamping onset across production lots and enables precise coordination with downstream overvoltage protection thresholds in systems like automotive ECUs and industrial sensors.
Is the 1N6267-E3/73 RoHS compliant and lead-free?
Yes, the 1N6267-E3/73 carries the "E3" suffix, indicating full RoHS compliance per Directive 2011/65/EU and exemption 7a. Its matte tin-plated leads meet J-STD-002 solderability requirements and JESD 201 Class 1A whisker resistance, making it suitable for lead-free reflow processes up to 260 °C peak temperature.
Can the 1N6267-E3/73 be used in bidirectional configurations?
No - the 1N6267-E3/73 is strictly unidirectional. Bidirectional variants in the same family carry the "CA" suffix (e.g., 1N6267CA). Using the 1N6267-E3/73 in reverse-biased configurations risks permanent damage due to lack of symmetrical breakdown structure; always verify polarity marking (cathode band) during placement.
What is the maximum clamping voltage of the 1N6267-E3/73 under surge conditions?
The 1N6267-E3/73 exhibits a maximum clamping voltage (VC) of 10.5 V when subjected to its rated peak pulse current of 143 A using the standard 10/1000 µs waveform. This value is guaranteed across temperature and represents the highest voltage imposed on the protected circuit during worst-case transient events.
Does the 1N6267-E3/73 meet AEC-Q101 qualification?
The base 1N6267-E3/73 is commercial-grade and not AEC-Q101 qualified. However, the functionally identical part 1N6267AHE3_B (with HE3 suffix and revision code) is AEC-Q101 qualified for automotive applications. For mission-critical automotive use, specify the HE3 variant - the 1N6267-E3/73 remains appropriate for industrial and telecom applications where AEC-Q101 is not mandated.
