Product details
Overview
1N6269AHE3_B/C 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 8.2 V breakdown voltage (VBR = 7.79–8.61 V at 10 mA), 7.02 V standoff voltage (VWM), 12.1 V clamping voltage (VC at 124 A), 1500 W peak pulse power (10/1000 µs), and operates across –55 °C to +175 °C junction temperature. It is used to protect MOSFETs, ICs, and sensor interfaces against inductive switching transients and lightning-induced surges.
For engineers reviewing the 1N6269AHE3_B/C datasheet, 1N6269AHE3_B/C pinout, 1N6269AHE3_B/C application, or 1N6269AHE3_B/C equivalent, this part delivers verified bidirectional-capable TVS performance with AEC-Q101 qualification (HE3 suffix), RoHS-compliant matte tin plating, and JESD 201 Class 2 whisker resistance - critical for automotive, industrial, and telecom surge protection design.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction to achieve sub-nanosecond response time (<1 ns) and low incremental surge resistance. Its clamping behavior is characterized by a tightly controlled VC/VBR ratio of ~1.55 and a temperature coefficient of +0.065 %/°C, ensuring stable protection threshold across operating temperatures.
The device is rated for 200 A non-repetitive forward surge current (8.3 ms half-sine), supports 6.5 W steady-state power dissipation on infinite heatsink at TL = 75 °C, and exhibits 75 °C/W junction-to-ambient thermal resistance - confirming suitability for high-energy transient suppression without active cooling in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.79 V / 8.61 V at 10 mA - defines precise voltage threshold where clamping initiates under standardized test conditions |
| VWM | 7.02 V - maximum continuous reverse working voltage before leakage exceeds 200 µA; sets safe operating margin below breakdown |
| VC at IPPM | 12.1 V at 124 A - clamped voltage during 1500 W transient, limiting downstream component stress to ≤12.1 V |
| PPPM | 1500 W (10/1000 µs waveform) - enables single-device protection against high-energy surges common in automotive load-dump or industrial switching events |
| TJ max. | +175 °C - allows operation in under-hood automotive or high-temperature industrial environments without derating |
| IFSM | 200 A (8.3 ms half-sine) - supports robust handling of repetitive inductive kickback without bond-wire failure |
| Package | Case Style 1.5KE - axial-leaded DO-201AD package with 0.375" lead length, UL 94 V-0 molded epoxy body |
Pinout & Package
1N6269AHE3_B/C is housed in a DO-201AD (Case Style 1.5KE) axial-leaded package. The cathode is marked by a color band on the body; polarity must be observed in series protection configurations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to protected circuit ground or low-side reference | Enables unidirectional clamping from line-to-ground; must be tied to lowest potential node in protection path |
| Cathode | Current exit point in forward bias; marked by color band; connected to protected line or signal | Defines clamping direction: reverse-biased during overvoltage, shunting surge current to ground through cathode |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A | Lower PPPM (400 W), smaller SMA package (SOD-123), VBR = 8.89–9.82 V, VC = 13.6 V at 29.4 A | Better suited for space-constrained PCBs with lower-energy threats (IEC 61000-4-2 ESD only); not rated for load-dump | Select when board area is critical and surge energy is limited to <500 W; verify thermal margin due to higher RθJA (~150 °C/W) |
| 1.5KE8.2A-E3/54 | Same electrical specs and DO-201AD package, but commercial-grade (E3 suffix), no AEC-Q101 qualification or JESD 201 Class 2 whisker test | Acceptable for non-automotive industrial or consumer applications where automotive reliability is not mandated | Choose for cost-sensitive designs where AEC-Q101 and enhanced whisker resistance are unnecessary; identical footprint and solder profile |
Compared with 1N6269AHE3_B/C, SMAJ8.0A trades surge capacity and automotive qualification for compact size, while 1.5KE8.2A-E3/54 matches form-fit-function but omits AEC-Q101 validation and whisker mitigation - making 1N6269AHE3_B/C the sole choice for production automotive systems requiring both high-energy clamping and long-term interconnect reliability.

FAQ
What is the breakdown voltage range of the 1N6269AHE3_B/C?
The 1N6269AHE3_B/C has a guaranteed breakdown voltage (VBR) range of 7.79 V to 8.61 V at a test current of 10 mA, measured per JEDEC standard. This tight tolerance ensures predictable clamping onset and compatibility with 5 V or 3.3 V logic-supplied protection circuits where margin above VWM (7.02 V) is critical. The value is confirmed in Vishay's official datasheet revision 09-Aug-2022, Document Number 88301.
Is the 1N6269AHE3_B/C suitable for automotive applications?
Yes, the 1N6269AHE3_B/C is AEC-Q101 qualified (as indicated by the HE3 suffix), making it suitable for automotive applications including engine control modules, body control units, and ADAS sensor interfaces. It meets JESD 201 Class 2 whisker resistance and operates reliably from –55 °C to +175 °C, satisfying under-hood thermal and long-term reliability requirements defined in the 1N6269AHE3_B/C datasheet.
What is the clamping voltage of the 1N6269AHE3_B/C at its rated peak pulse current?
The 1N6269AHE3_B/C clamps to a maximum of 12.1 V at its peak pulse current (IPPM) of 124 A, tested with a 10/1000 µs waveform. This VC value directly determines the maximum voltage imposed on protected circuitry during surge events and is validated in the "Electrical Characteristics" table of the 1N6269AHE3_B/C datasheet (Document Number 88301).
Does the 1N6269AHE3_B/C have bidirectional capability?
No, the 1N6269AHE3_B/C is a unidirectional TVS diode. Its part number lacks the "C" suffix (e.g., 1N6269CA), which denotes bidirectional variants. As a unidirectional device, it conducts only in reverse bias during overvoltage events and requires correct polarity installation - cathode connected to the line being protected, anode to ground - to function as intended per the 1N6269AHE3_B/C specification.
What package type does the 1N6269AHE3_B/C use, and what are its key mechanical features?
