Product details
Overview
1N6290A-E3/51 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 62 V breakdown voltage (VBR = 58.9–65.1 V at 1.0 mA), 1500 W peak pulse power (10/1000 µs), clamping voltage of 85.0 V at 17.6 A, and operates across –55 °C to +175 °C. It is used to protect MOSFETs, ICs, and sensor interfaces against lightning-induced transients and inductive switching surges.
For engineers reviewing the 1N6290A-E3/51 datasheet, 1N6290A-E3/51 pinout, 1N6290A-E3/51 application, or 1N6290A-E3/51 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, clamping behavior under surge conditions, thermal resistance (RθJA = 75 °C/W), and RoHS-compliant commercial-grade sourcing at Aetrix Electronics.
Technical Context
This unidirectional TVS diode employs a glass-passivated silicon junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its clamping action begins at 53.0 V stand-off voltage (VWM) and limits peak voltage to 85.0 V under 17.6 A 10/1000 µs surge current - critical for safeguarding 60 V-rated logic and power stages.
The device is rated for 200 A non-repetitive forward surge (8.3 ms half-sine), dissipates 6.5 W on infinite heatsink at TL = 75 °C, and exhibits a temperature coefficient of VBR at +0.104 %/°C - enabling stable protection across automotive and industrial ambient ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at 1.0 mA - defines precise voltage threshold where clamping initiates |
| VWM | 53.0 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 85.0 V at 17.6 A - peak clamped voltage during 1500 W transient, limiting stress on downstream components |
| PPPM | 1500 W (10/1000 µs waveform) - sustains high-energy surges without failure in telecom and industrial power rails |
| IFSM | 200 A (8.3 ms half-sine) - withstands repetitive inrush or fault currents in DC-DC converter inputs |
| TJ range | –55 °C to +175 °C - supports operation in under-hood automotive and high-temp industrial environments |
| RθJA | 75 °C/W - enables thermal design with standard PCB copper area; no active cooling required for intermittent surges |
Pinout & Package
Package: JEDEC DO-201AD (Case Style 1.5KE), molded epoxy body with matte tin-plated leads; RoHS-compliant E3 suffix; 0.375" (9.5 mm) lead length; UL 94 V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Reverse-biased anode connection point | Connected to protected line; conducts during overvoltage to shunt current to ground |
| Anode | Reference/ground return path | Typically tied to system ground or low-impedance return plane to complete clamping loop |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable VBR tolerance and long-term reliability under humidity and thermal cycling |
| 1500 W peak pulse power | Handles lightning surge waveforms (IEC 61000-4-5 Level 4) without degradation in 48 V power systems |
| Clamping ratio (VC/VBR) ≈ 1.31 | Minimizes overvoltage margin between trip point and clamp level - critical for 65 V-rated MOSFET gate drivers |
| Response time < 1 ns | Activates before most semiconductor junctions can be damaged by fast-rising ESD or switching transients |
| Solderable per J-STD-002/JESD 22-B102 | Compatible with standard reflow and wave solder processes; no special pre-treatment required |
Applications
| Automotive Power Distribution | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 48 V battery management system (BMS) input stages from load dump and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between input rail and ground to clamp surges above 53 V while remaining inert during normal operation. Use Value: Limits peak voltage to 85.0 V, ensuring compliance with ISO 16750-2 Pulse 5a/b and preventing damage to buck controller ICs rated ≤ 100 V. |
Use Scenario: Shielding analog front-end (AFE) inputs of pressure/temperature sensors in PLC modules from field-wiring induced transients. IC Role / Device Role / Timing Role: Standoff protection element on sensor supply line, activated only during >53 V faults to preserve signal integrity. Use Value: Low leakage (<1 µA at 53 V) avoids DC offset errors; fast <1 ns response prevents ADC saturation during EFT bursts. |
| Telecom DC Power Feeds | Motor Drive Gate Driver Protection |
Use Scenario: Safeguarding -48 V telecom rectifier outputs against lightning-induced common-mode surges on outdoor cable runs. IC Role / Device Role / Timing Role: Primary overvoltage clamp on output rail, coordinated with upstream MOVs for staged energy absorption. Use Value: 1500 W rating handles 10/1000 µs surges up to 17.6 A; 85.0 V clamping ensures downstream DC-DC converters remain within absolute max ratings. |
Use Scenario: Protecting high-side gate driver ICs in 3-phase inverters from Miller-induced voltage spikes during IGBT switching. IC Role / Device Role / Timing Role: Localized TVS across gate-to-source (G-S) of SiC MOSFETs to suppress dv/dt-induced false turn-on. Use Value: Tight VBR tolerance (±5%) and 85.0 V clamp prevent gate oxide overstress while maintaining noise immunity at 20 kHz PWM frequencies. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A | Lower PPPM (600 W), smaller SMB package (lower IPPM = 9.9 A), VC = 104 V at 5.8 A | Better suited for space-constrained PCBs with lower surge energy requirements (e.g., USB-C PD ports) | Select when board area is limited and surge threat level is IEC 61000-4-5 Level 2; not suitable for 48 V load dump. |
| 1.5KE62AHE3_A | Identical electrical specs but AEC-Q101 qualified; same DO-201AD package; higher reliability screening for automotive use | Required for under-hood ECUs, ADAS camera modules, and other AEC-Q101-mandated applications | Choose for automotive production programs needing qualification evidence; otherwise 1N6290A-E3/51 suffices for commercial/industrial use. |
Compared with SMBJ64A, 1N6290A-E3/51 delivers 2.5× higher surge power handling and tighter clamping for 48–60 V systems; versus 1.5KE62AHE3_A, it offers identical protection performance at lower cost and qualification overhead for non-automotive designs.

FAQ
What is the breakdown voltage tolerance for 1N6290A-E3/51?
The 1N6290A-E3/51 has a specified breakdown voltage range of 58.9 V to 65.1 V at 1.0 mA test current, representing ±5% tolerance around the nominal 62 V rating. This tight VBR window ensures predictable clamping onset in 48–60 V systems and aligns with JEDEC 1.5KE standards. The value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's 88301 datasheet revision 09-Aug-2022.
Is 1N6290A-E3/51 RoHS compliant and lead-free?
Yes, the "E3" suffix in 1N6290A-E3/51 explicitly denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads. It meets JESD 201 Class 1A whisker testing and complies with EU Directive 2011/65/EU. No lead or heavy metals exceed permitted thresholds, and the molding compound satisfies UL 94 V-0 flammability requirements.
Can 1N6290A-E3/51 be used in bidirectional configurations?
No, 1N6290A-E3/51 is strictly unidirectional - indicated by the "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., 1.5KE62CA). Using 1N6290A-E3/51 in reverse-biased AC applications would result in forward conduction and failure. For bidirectional protection at ~62 V, select 1.5KE62CA instead.
What is the maximum clamping voltage of 1N6290A-E3/51 under surge conditions?
The maximum clamping voltage (VC) of 1N6290A-E3/51 is 85.0 V at 17.6 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is guaranteed per datasheet Table on page 2 and reflects worst-case clamping under full-rated surge power. It ensures protected circuits see no more than 85.0 V during transient events.
Does 1N6290A-E3/51 require a heatsink for continuous operation?
No heatsink is required for transient suppression duty, as 1N6290A-E3/51 is rated for 6.5 W power dissipation on an infinite heatsink at TL = 75 °C - sufficient for typical surge intervals (duty cycle ≤ 0.01%). However, for sustained DC leakage or frequent surges, PCB copper area ≥ 1 in² per lead is recommended to maintain TJ ≤ 175 °C. RθJA = 75 °C/W confirms natural convection adequacy.
