Product details
Overview
1N6292-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary-side overvoltage protection in power rails and signal lines. It features a 71.3 V to 78.8 V breakdown voltage (VBR) at 1 mA, 64.1 V maximum standoff voltage (VWM), 1500 W peak pulse power (10/1000 µs), clamps to ≤104 V at 14.6 A peak pulse current, and operates from –55 °C to +175 °C - used in automotive power supply input stages and industrial DC bus protection.
For engineers reviewing the 1N6292-E3/73 datasheet, 1N6292-E3/73 pinout, 1N6292-E3/73 application, or 1N6292-E3/73 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, clamping behavior under surge conditions, thermal derating guidance, and validated alternative parts for ESD/lightning transient suppression in high-reliability systems.
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 1500 W peak pulse power rating is defined per 10/1000 µs waveform with 0.01% duty cycle, and it maintains stable clamping performance across –55 °C to +175 °C operating junction temperature.
The device complies with JEDEC standard 1.5KE case outline, features matte tin-plated leads solderable per J-STD-002, and meets RoHS requirements (E3 suffix). It is not AEC-Q101 qualified - only HE3-suffix variants (e.g., 1.5KE75AHE3_B) carry that qualification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 71.3 V / 78.8 V at 1 mA test current - defines reliable conduction onset for overvoltage events above nominal rail. |
| VWM | 64.1 V maximum - ensures no leakage or false triggering below system's maximum steady-state voltage. |
| IPPM | 14.6 A at 10/1000 µs - quantifies maximum surge current the device safely clamps without failure. |
| VC | ≤104 V at IPPM - specifies worst-case clamped voltage seen by protected downstream circuitry. |
| PPPM | 1500 W peak pulse power - enables robust handling of lightning-induced transients (IEC 61000-4-5 Level 4). |
| TJ range | –55 °C to +175 °C - supports operation in under-hood automotive and industrial environments without derating loss. |
| RθJA | 75 °C/W - informs thermal design margin when mounted on PCB without heatsink. |
Pinout & Package
Package: JEDEC 1.5KE molded epoxy case (DO-201AD), axial leaded, RoHS-compliant E3 finish. Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current sink path during reverse-biased clamping | Connected to protected line (e.g., +12 V rail); conducts surge current to ground when VLINE exceeds VBR. |
| Cathode | Reference node for clamping threshold | Marked with color band; tied to system ground or low-impedance return path to establish VWM/VBR reference. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable VBR tolerance (±5%) and long-term reliability under repeated surge stress. |
| 1500 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 4th-level surge immunity testing without external series impedance. |
| Sub-nanosecond response time | Clamps transients before sensitive ICs (e.g., MCU power pins or CAN transceivers) experience overstress. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising surges (e.g., EFT bursts), improving protection margin. |
| RoHS-compliant E3 finish | Meets JESD 201 Class 1A whisker resistance for lead-free reflow and wave soldering processes. |
Applications
| Automotive Power Input Protection | Industrial DC Bus Surge Suppression |
|---|---|
Use Scenario: 12 V battery feed line exposed to load dump (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and main DC/DC converter input. Use Value: Clamps transients up to 104 V while limiting energy delivered to downstream regulator, preventing latch-up or gate oxide damage. |
Use Scenario: 48 V DC distribution bus in factory automation PLCs subjected to inductive switching spikes. IC Role / Device Role / Timing Role: Primary overvoltage clamp on bus input, upstream of isolation and regulation stages. Use Value: Absorbs 1500 W surges without degradation, maintaining bus integrity during contactor switching or motor drive faults. |
| Telecom Line Interface Protection | Consumer Power Adapter Output Clamping |
Use Scenario: Secondary-side 5 V/12 V output of PoE-powered Ethernet switch exposed to induced surges. IC Role / Device Role / Timing Role: Final-stage TVS on regulated output rail before connector interface. Use Value: Prevents surge propagation into connected endpoint devices (e.g., IP cameras) with guaranteed ≤104 V clamping ceiling. |
Use Scenario: Output of wall-mounted AC/DC adapter supplying smart home hubs, subject to mains-borne transients. IC Role / Device Role / Timing Role: Output-side TVS ensuring safe voltage delivery despite poor-quality grid conditions. Use Value: Maintains <64.1 V standby compliance while surviving repetitive 1500 W surges per UL 1449 requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ70A | Lower PPPM (600 W), smaller SMB package (vs. DO-201AD), VBR = 77.8–86.0 V | Preferred where board space is constrained and 600 W surge level suffices (e.g., secondary-side consumer electronics) | Select SMBJ70A when footprint reduction outweighs need for 1500 W capability and higher IPPM headroom. |
| 1.5KE75A | Identical electrical specs and JEDEC 1.5KE package; differs only in packaging format (E3/73 vs. E3/54 tape-and-reel) | No functional difference - same die, same test limits, same thermal profile | Choose 1.5KE75A for alternate reel configuration (1400 pcs/reel, 54 mm tape) if production line requires different feeding setup. |
Compared with 1N6292-E3/73, SMBJ70A trades surge capacity and thermal mass for compactness, while 1.5KE75A offers identical protection performance in a functionally interchangeable package - enabling drop-in substitution where reel logistics permit.

FAQ
What is the breakdown voltage range of the 1N6292-E3/73?
The 1N6292-E3/73 has a specified breakdown voltage (VBR) range of 71.3 V to 78.8 V at 1 mA test current, per Vishay Document 88301. This tight tolerance ensures predictable clamping onset across production lots and temperature extremes, critical for protecting 60–72 V nominal systems like 48 V automotive architectures or industrial control buses. The 1N6292-E3/73 achieves this via glass-passivated junction processing.
Is the 1N6292-E3/73 AEC-Q101 qualified?
No, the 1N6292-E3/73 is not AEC-Q101 qualified. Only variants with the HE3 suffix (e.g., 1.5KE75AHE3_B) carry AEC-Q101 qualification per Vishay's ordering information. The E3 suffix indicates RoHS compliance and commercial-grade qualification only. For automotive under-hood applications requiring AEC-Q101, engineers must select the HE3 version - the 1N6292-E3/73 remains suitable for non-automotive industrial or telecom use where qualification is not mandated.
What is the maximum clamping voltage of the 1N6292-E3/73 at rated peak pulse current?
The 1N6292-E3/73 clamps to a maximum of 104 V at its rated peak pulse current (IPPM) of 14.6 A, measured using the standard 10/1000 µs waveform. This value is confirmed in the Electrical Characteristics table of Vishay Document 88301. The low clamping ratio (VC/VBR ≈ 1.46) reflects optimized junction design and ensures downstream components see minimal overvoltage stress during surge events.
Can the 1N6292-E3/73 be used in bidirectional configurations?
No, the 1N6292-E3/73 is a unidirectional TVS diode and cannot be used for bidirectional transient suppression. Bidirectional variants in the same family use the "CA" suffix (e.g., 1.5KE75CA). The 1N6292-E3/73 has polarity - cathode marked by a band - and conducts only in reverse bias. Using it in bidirectional circuits would leave positive-going transients unprotected, risking system failure. Always verify polarity marking and select CA-suffix parts for AC-coupled or symmetrical line protection.
What is the thermal resistance junction-to-ambient for the 1N6292-E3/73?
The 1N6292-E3/73 has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W, as stated in the Thermal Characteristics section of Vishay Document 88301. This value assumes standard mounting on FR-4 PCB with minimum copper area. Engineers must apply this RθJA with ambient temperature and power dissipation data to calculate worst-case junction temperature - especially important for repeated surge events where cumulative heating affects long-term reliability of the 1N6292-E3/73.
