Product details
Overview
1N6267AHE3_B/C from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection of sensitive electronics. It features a 6.45 V to 7.14 V breakdown voltage (VBR) at 10 mA, 5.80 V maximum standoff voltage (VWM), 1000 µA maximum reverse leakage at VWM, 143 A peak pulse current (IPPM), and clamps transients to 10.5 V at IPPM. It is used in power supply input stages and DC bus lines to protect MOSFETs and ICs against inductive switching surges.
For engineers reviewing the 1N6267AHE3_B/C datasheet, 1N6267AHE3_B/C pinout, 1N6267AHE3_B/C application, or 1N6267AHE3_B/C equivalent, this part delivers 1500 W peak pulse power (10/1000 µs), AEC-Q101 qualification (HE3 suffix), RoHS-compliant matte tin-plated leads, and UL 94 V-0 molded epoxy packaging - critical for automotive, industrial, and telecom surge protection design validation.
Technical Context
This unidirectional TVS diode operates as a voltage-clamping device with glass-passivated junction technology, enabling sub-nanosecond response time (<1 ns) to transient events. Its low incremental surge resistance and excellent clamping ratio (VC/VBR ≈ 1.48) ensure minimal overshoot during 1500 W surge events.
The device is rated for -55 °C to +175 °C operating junction temperature, with thermal resistance RθJA = 75 °C/W and RθJL = 15.4 °C/W. It supports 200 A non-repetitive forward surge current (IFSM) and exhibits a positive temperature coefficient of VBR (+0.057 %/°C), ensuring stable breakdown behavior across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 6.45 V to 7.14 V at 10 mA - defines precise clamping onset threshold for overvoltage detection |
| Standoff Voltage VWM | 5.80 V max - ensures no conduction during normal 5 V system operation, preventing false triggering |
| Clamping Voltage VC | 10.5 V at 143 A - limits downstream voltage stress to safe levels during 1500 W transients |

Applications
| Automotive Power Supply Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 5 V microcontroller power rails in vehicle infotainment modules exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed between VIN and GND, triggered within <1 ns upon overvoltage event. Use Value: Limits rail voltage to ≤10.5 V during 1500 W transients, preserving MCU functionality and avoiding latch-up. |
Use Scenario: Shielding analog sensor outputs (e.g., pressure or temperature sensors) in factory automation PLCs from EFT and surge coupling. IC Role / Device Role / Timing Role: Line-to-ground TVS on signal path, absorbing fast transients before reaching ADC input stage. Use Value: Maintains signal fidelity by clamping induced spikes below 10.5 V while adding <1 pF capacitance - negligible at DC–10 kHz bandwidth. |
| Telecom DC Power Input Protection | Consumer Device USB Port Protection |
Use Scenario: Safeguarding 48 V PoE-powered equipment front-end against lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Primary-stage unidirectional TVS on DC input, coordinated with upstream fuse and secondary MOV. Use Value: Absorbs up to 143 A peak current (10/1000 µs), reducing downstream component stress and extending system MTBF. |
Use Scenario: Preventing damage to USB controller ICs in smart home hubs due to human-body-model (HBM) ESD events. IC Role / Device Role / Timing Role: Low-capacitance TVS on VBUS line, activated before internal ESD diodes reach breakdown. Use Value: Clamps 8 kV contact discharge to ≤10.5 V within 1 ns, eliminating data corruption and port lockup. |
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-E3/52 | DO-214AA package; lower PPPM (600 W); VBR = 7.14–7.88 V; higher VC = 11.2 V at 53.3 A | Preferred for space-constrained PCBs where 1.5KE axial leads are impractical | Select SMBJ6.8A-E3/52 when board area is limited and 600 W surge rating suffices for target threat level |
| 1.5KE6.8A-E3/54 | Same 1.5KE package and electrical specs; commercial-grade (non-AEC-Q101); E3 suffix only (no HE3_B/C revision) | Suitable for non-automotive industrial or consumer applications requiring identical performance without automotive qualification | Choose 1.5KE6.8A-E3/54 for cost-sensitive designs where AEC-Q101 is not mandated and JEDEC tape-and-reel delivery is preferred |
Compared with 1N6267AHE3_B/C, SMBJ6.8A-E3/52 trades surge capacity and automotive qualification for compactness, while 1.5KE6.8A-E3/54 retains identical clamping and package but omits AEC-Q101 validation - making it viable for non-automotive use cases where qualification overhead is unnecessary.

FAQ
What is the breakdown voltage range of the 1N6267AHE3_B/C?
The 1N6267AHE3_B/C has a guaranteed breakdown voltage (VBR) range of 6.45 V to 7.14 V measured at 10 mA test current. This tight tolerance ensures consistent clamping behavior across production lots and supports reliable overvoltage detection in 5 V systems where margin above nominal rail is critical.
Is the 1N6267AHE3_B/C suitable for automotive applications?
Yes, the 1N6267AHE3_B/C is AEC-Q101 qualified (denoted by the HE3 suffix and revision code B/C), having passed stress tests including temperature cycling, high-temperature reverse bias, and unbiased highly accelerated stress testing - making it approved for under-hood and chassis-mounted automotive electronics.
What does the "HE3_B/C" suffix indicate in 1N6267AHE3_B/C?
The "HE3" denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "B/C" specifies the manufacturing revision level per Vishay's internal change control, confirming compliance with the 09-Aug-2022 revision of document 88301 and updated reliability screening protocols.
How does the clamping voltage of 1N6267AHE3_B/C compare to its breakdown voltage?
The 1N6267AHE3_B/C clamps at 10.5 V when subjected to its rated peak pulse current of 143 A (10/1000 µs waveform), resulting in a clamping ratio (VC/VBR) of approximately 1.48 - a low value indicating efficient energy diversion and minimal overvoltage stress on protected circuitry.
Can the 1N6267AHE3_B/C be used in bidirectional configurations?
No, the 1N6267AHE3_B/C is a unidirectional TVS diode, identifiable by its cathode band marking. For bidirectional protection, Vishay offers the 1N6267CA variant (or 1.5KE6.8CA), which lacks polarity marking and provides symmetrical clamping in both directions - the 1N6267AHE3_B/C must be oriented correctly in-circuit to function.
