Product details
Overview
1N6285-E3/54 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 39 V breakdown voltage (VBR min/max: 37.1–41.0 V), 33.3 V standoff voltage (VWM), 1500 W peak pulse power (10/1000 µs), 53.9 V clamping voltage at 27.8 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 in industrial and automotive systems.
For engineers reviewing the 1N6285-E3/54 datasheet, 1N6285-E3/54 pinout, 1N6285-E3/54 application, or 1N6285-E3/54 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, thermal resistance (RθJA = 75 °C/W), polarity marking (cathode band), and direct alternatives with documented clamping and standoff differences.
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 defined by a 10/1000 µs waveform test condition, with a maximum clamping voltage of 53.9 V at 27.8 A peak pulse current (IPPM).
The device complies with JEDEC standard 1.5KE case style, features matte tin-plated leads solderable per J-STD-002, and meets RoHS requirements (E3 suffix). It is rated for 200 A non-repetitive forward surge current (IFSM) and exhibits a temperature coefficient of VBR of +0.100 %/°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 37.1 V / 41.0 V - Ensures reliable conduction onset above normal operating voltage while avoiding false triggering |
| VWM | 33.3 V - Maximum continuous reverse working voltage before leakage exceeds 1 µA |
| VC @ IPPM | 53.9 V at 27.8 A - Clamped voltage during 1500 W transient, defining protected circuit's worst-case overvoltage |
| PPPM | 1500 W (10/1000 µs) - Sustains high-energy transients common in automotive load-dump or industrial switching events |
| IFSM | 200 A (8.3 ms half-sine) - Withstands single large inrush surges without bond-wire failure |
| TJ max | +175 °C - Enables operation in under-hood automotive or high-ambient industrial environments |
| RθJA | 75 °C/W - Defines thermal derating on PCB without heatsink; limits steady-state power to ~6.5 W at TL = 75 °C |
Pinout & Package
1N6285-E3/54 is housed in the industry-standard axial-lead JEDEC 1.5KE package (Case Style 1.5KE), with cathode indicated by a color band. The device has two terminals: anode and cathode. No internal circuitry or additional pins are present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to protected circuit ground or low-side return path | Provides low forward voltage drop (~3.5 V at 100 A) during surge conduction to shunt energy safely to ground |
| Cathode | Current exit point in forward bias; marked with color band; connected to line being protected | Defines polarity-sensitive placement-must be oriented toward positive rail to clamp positive transients |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable VBR tolerance (±5 %) and long-term reliability under humidity and thermal cycling |
| 1500 W peak pulse rating | Meets IEC 61000-4-5 Level 4 surge immunity (4 kV line-to-line) when properly mounted |
| Sub-nanosecond response | Clamps transients before sensitive downstream components (e.g., MCU I/O, gate drivers) experience overstress |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker resistance and J-STD-002 solderability standards for high-reliability assembly |
| –55 °C to +175 °C operation | Supports deployment in engine control units, motor drives, and outdoor telecom equipment without derating |

IC Role / Device Role / Timing Role: Primary overvoltage clamp on DC input, coordinated with upstream MOVs and secondary TVS stages. Use Value: Absorbs 1500 W surge energy without degradation, ensuring uninterrupted operation after repeated lightning-induced transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ39A | Same VWM (33.3 V) and VC (60.0 V), but lower PPPM (600 W); SMC package (smaller footprint, higher RθJA = 12°C/W) | Preferred for space-constrained PCBs where 600 W surge margin suffices; unsuitable for sustained 1500 W events | Select SMBJ39A only if layout area is critical and surge threat level is ≤Level 3 (2 kV) per IEC 61000-4-5 |
| 1.5KE39A | Identical electrical specs and 1.5KE package; differs only in packaging format (bulk vs. tape-and-reel E3/54) and traceability | No functional difference; same thermal performance, clamping, and reliability; fully interchangeable in design | Choose 1.5KE39A for manual prototyping or small-batch builds; 1N6285-E3/54 preferred for automated SMT assembly with 13" reel delivery |
Compared with SMBJ39A and 1.5KE39A, the 1N6285-E3/54 provides identical surge clamping performance and thermal capability in a RoHS-compliant, tape-and-reel optimized variant-making it ideal for high-volume automotive and industrial production where supply chain traceability and assembly compatibility are essential.

FAQ
What is the breakdown voltage range for the 1N6285-E3/54?
The 1N6285-E3/54 has a specified breakdown voltage (VBR) range of 37.1 V to 41.0 V at 1.0 mA test current. This tolerance ensures consistent clamping onset across production lots while maintaining safe margin above its 33.3 V maximum working voltage (VWM). The value is measured per JEDEC standard and confirmed in Vishay's 88301 datasheet revision 09-Aug-2022.
Is the 1N6285-E3/54 unidirectional or bidirectional?
1N6285-E3/54 is a unidirectional TVS diode. Its polarity is marked by a cathode band, and it conducts only during positive voltage transients relative to the cathode. Bidirectional variants (e.g., 1N6285CA) exist in the same family but are distinct part numbers-not interchangeable with 1N6285-E3/54 without circuit redesign.
What is the clamping voltage of the 1N6285-E3/54 at its rated peak pulse current?
The 1N6285-E3/54 clamps to a maximum of 53.9 V at its rated peak pulse current of 27.8 A (10/1000 µs waveform). This value defines the upper voltage limit imposed on protected circuitry during a full 1500 W transient event and is critical for verifying compatibility with downstream component voltage ratings.
Does the 1N6285-E3/54 meet AEC-Q101 qualification?
No-the 1N6285-E3/54 is a commercial-grade part (E3 suffix). AEC-Q101 qualified versions carry the HE3 suffix (e.g., 1N6285AHE3_B). While electrically identical, the HE3 variant undergoes additional stress testing per AEC-Q101 for automotive under-hood use; the 1N6285-E3/54 is approved for industrial and general-purpose applications per Vishay Document 88301.
What package type and lead finish does the 1N6285-E3/54 use?
The 1N6285-E3/54 uses the axial-leaded JEDEC 1.5KE package (Case Style 1.5KE) with matte tin-plated leads. It complies with J-STD-002 for solderability and JESD 201 Class 1A for whisker resistance. The E3 suffix confirms RoHS compliance and commercial-grade qualification per Vishay's material categorization system.
