Product details
Overview
1N6298A-E3/54 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 130 V breakdown voltage (VBR = 124–137 V), 111 V maximum working voltage (VWM), 179 V clamping voltage at 8.4 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces in industrial power supplies and automotive control modules.
For engineers reviewing the 1N6298A-E3/54 datasheet, 1N6298A-E3/54 pinout, 1N6298A-E3/54 application, or 1N6298A-E3/54 equivalent, this part delivers verified transient suppression performance in high-energy surge environments where fast response (<1 ns), low clamping ratio (VC/VWM ≈ 1.61), and AEC-Q101-qualified reliability are required.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: it remains high-impedance below VWM (111 V), then avalanches sharply at VBR (min 124 V, max 137 V) to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 µA at VWM).
It handles non-repetitive 10/1000 µs surges up to 8.4 A (IPPM), with clamping voltage VC = 179 V - limiting voltage stress on protected devices. Thermal resistance is RθJA = 75 °C/W and RθJL = 15.4 °C/W, supporting lead-mounted dissipation of 6.5 W at TL = 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 124–137 V at 1.0 mA test current - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| Stand-off Voltage VWM | 111 V maximum - ensures no conduction during normal 110 VDC rail operation, minimizing standby leakage |
| Clamping Voltage VC | 179 V at 8.4 A IPPM - limits transient voltage seen by protected ICs to safe margin below absolute maximum ratings |
| Peak Pulse Power PPPM | 1500 W (10/1000 µs) - sustains high-energy lightning-induced surges without failure |
| Peak Pulse Current IPPM | 8.4 A - quantifies maximum surge current the device can safely shunt per event |
| Maximum Leakage ID | <1 µA at VWM - prevents measurable power loss or false triggering in low-power circuits |
| Junction Temperature Range | –55 °C to +175 °C - supports operation in under-hood automotive and industrial ambient extremes |
Pinout & Package
Package: 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 |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or low-voltage return path; defines cathode-referenced clamping behavior |
| Cathode | High-side surge input terminal | Connected to protected line (e.g., 110 VDC bus); color band denotes this end per JEDEC standard |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance (±5%), low leakage, and long-term reliability under thermal cycling |
| 1500 W peak pulse power | Withstands IEC 61000-4-5 Level 4 (4 kV) surges on 110 VDC systems without degradation |
| Sub-nanosecond response time | Clamps transients within <1 ns - faster than MOVs or polymer-based protectors, preserving signal integrity |
| AEC-Q101 qualified option available | HE3 variant meets automotive-grade stress testing (temperature cycling, HTRB, etc.) for engine control units |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., inductive switch-off spikes) |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module |
|---|---|
Use Scenario: 110 VDC input stage of programmable logic controller (PLC) power supply exposed to load dump and inductive switching noise. IC Role / Device Role: Primary shunt TVS placed between input rail and chassis ground to clamp surges before they reach DC-DC converter ICs. Use Value: Limits transient voltage to ≤179 V, preventing damage to 200 V-rated input capacitors and 150 V MOSFETs in the front-end rectifier stage. |
Use Scenario: LIN bus interface in door module subjected to ESD and battery reverse-polarity events during service. IC Role / Device Role: Unidirectional TVS on LIN data line referenced to vehicle ground, protecting transceiver IC inputs. Use Value: Clamps 10/1000 µs surges to 179 V while maintaining <1 µA leakage at 12 V nominal - avoids false wake-up or communication errors. |
| Telecom Remote Terminal Unit | Renewable Energy Inverter DC Link |
Use Scenario: Outdoor DSLAM cabinet powered via PoE++ or remote 48 VDC feed, vulnerable to induced lightning surges on copper pairs. IC Role / Device Role: First-stage TVS on DC input rail upstream of DC-DC isolation stage. Use Value: Absorbs 1500 W surges without thermal runaway; RθJL = 15.4 °C/W enables direct PCB trace heatsinking without extra copper pour. |
Use Scenario: DC link between PV array and MPPT controller in solar microinverter, subject to rapid voltage transients during partial shading transitions. IC Role / Device Role: Bidirectional-capable unidirectional TVS (used anode-grounded) across DC+ and DC− to suppress common-mode surges. Use Value: Withstands repetitive 8.4 A pulses at 0.01% duty cycle - protects 600 V IGBT gate drivers from overvoltage latch-up. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A | Same VWM (111 V) and VC (179 V), but lower PPPM (600 W) and smaller SMB package (RθJA = 110 °C/W) | Suitable only for lower-energy surges (IEC 61000-4-5 Level 2); not recommended for 110 VDC industrial mains input | Select 1N6298A-E3/54 when 1500 W surge handling and lead-mounted thermal performance are mandatory. |
| 1.5KE130A | Identical electrical specs and case style; differs only in packaging (bulk vs. tape-and-reel E3/54) and marking convention | No functional difference; both meet same JEDEC 1.5KE mechanical and electrical standards | 1N6298A-E3/54 is the exact same device as 1.5KE130A - dual-marking per Vishay's cross-reference table (Document 88301, p.2). |
Compared with SMBJ130A, 1N6298A-E3/54 provides 2.5× higher surge power margin and superior thermal dissipation for sustained surge events; compared with 1.5KE130A, it is functionally identical but supplied in 13" paper tape (54 per reel) with RoHS-compliant E3 finish - enabling automated SMT placement and traceable sourcing.

FAQ
What is the breakdown voltage tolerance of the 1N6298A-E3/54?
The 1N6298A-E3/54 has a specified breakdown voltage range of 124 V to 137 V at 1.0 mA test current, representing a ±5% tolerance around the nominal 130 V rating. This tight VBR window ensures consistent clamping behavior across production lots and supports predictable system-level surge margin design without over-engineering downstream protection.
Is the 1N6298A-E3/54 suitable for automotive applications?
The 1N6298A-E3/54 itself is commercial-grade; however, its AEC-Q101-qualified variant - 1N6298AHE3_B - is explicitly certified for automotive use. Engineers designing for under-hood or body control modules should specify the HE3_B suffix version to ensure compliance with temperature cycling, humidity bias, and high-temperature reverse bias requirements defined in AEC-Q101.
How does the clamping voltage of the 1N6298A-E3/54 compare to its working voltage?
The 1N6298A-E3/54 clamps at 179 V (VC) when subjected to its rated 8.4 A peak pulse current, while its maximum working voltage (VWM) is 111 V. This yields a clamping ratio of ~1.61, indicating efficient voltage limiting - critical for protecting 200 V-rated components without excessive derating or cascaded protection stages.
What is the thermal resistance of the 1N6298A-E3/54 and how does it affect layout?
The 1N6298A-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 15.4 °C/W and junction-to-ambient (RθJA) of 75 °C/W. This means effective heat removal relies primarily on copper traces connected to its leads - not just pad area. Layouts should use ≥0.5 mm wide, 2 oz copper traces extending ≥10 mm from each lead to act as thermal vias and heatsinks.
Can the 1N6298A-E3/54 be used in bidirectional configurations?
No - the 1N6298A-E3/54 is a unidirectional TVS diode, identifiable by its cathode band marking. For bidirectional protection at comparable voltage levels, Vishay offers the 1N6298CA (or 1.5KE130CA), which provides symmetrical clamping in both polarities. Using the unidirectional 1N6298A-E3/54 in reverse-biased AC applications risks permanent failure due to forward conduction.
