Product details
Overview
1N6289-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 53.2 V to 58.8 V breakdown voltage range at 1 mA test current, 47.8 V maximum standoff voltage, 77.0 V clamping voltage at 19.5 A peak pulse current, and 1500 W peak pulse power capability with a 10/1000 μs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the 1N6289-E3/54 datasheet, 1N6289-E3/54 pinout, 1N6289-E3/54 application, or 1N6289-E3/54 equivalent, this device delivers verified clamping performance, JEDEC-standardized 1.5KE package compatibility, RoHS-compliant matte tin plating, and thermal robustness up to 175 °C junction temperature - critical for automotive-grade surge immunity and high-reliability embedded systems.
Technical Context
This unidirectional TVS diode operates by avalanche breakdown to clamp transient voltages before they reach sensitive downstream components. Its glass-passivated junction ensures stable VBR tolerance (±5 %), low incremental surge resistance, and sub-nanosecond response time (<1 ns), enabling effective suppression of ESD, lightning-induced surges, and inductive switching spikes.
The device complies with JEDEC standard 1.5KE case outline, supports 200 A non-repetitive forward surge current (8.3 ms half-sine), and exhibits a +0.103 %/°C temperature coefficient of breakdown voltage - ensuring predictable clamping behavior across -55 °C to +175 °C operating range without thermal runaway.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 53.2 V / 58.8 V at 1 mA - defines precise avalanche onset window for reliable triggering without false trips |
| VWM | 47.8 V maximum - ensures no conduction during normal 48 V rail operation, preserving system efficiency |
| VC @ IPPM | 77.0 V at 19.5 A - limits worst-case transient voltage seen by protected ICs to safe margin below absolute max ratings |
| PPPM | 1500 W (10/1000 μs) - sustains high-energy transients common in motor drives and telecom line interfaces |
| IFSM | 200 A (8.3 ms half-sine) - withstands repetitive inrush or fault currents without bond wire failure |
| TJ max | +175 °C - enables deployment in under-hood automotive or high-ambient industrial enclosures |
| RθJL | 15.4 °C/W - allows direct PCB copper pour heatsinking to maintain reliability under sustained surge duty |
Pinout & Package
Package: JEDEC 1.5KE molded epoxy case (DO-201AD), axial leaded, RoHS-compliant matte tin plating, UL 94 V-0 rated molding compound. Cathode indicated by color band on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current sink path during reverse-biased clamping | Connected to protected circuit node; carries full IPPM during surge event |
| Cathode | Reference terminal tied to system ground or return rail | Color-banded end; establishes polarity-sensitive clamping direction for DC applications |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures ±5 % VBR tolerance and long-term stability under thermal cycling and humidity stress |
| 1500 W peak pulse power | Handles IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) without degradation in 48 V systems |
| Sub-nanosecond response | Clamps transients within 1 ns - faster than MOVs or polymer-based protectors, preserving signal integrity |
| Low clamping ratio (VC/VBR ≈ 1.38) | Minimizes let-through voltage, reducing stress on downstream 75 V-rated MOSFETs and interface ICs |
| AEC-Q101 qualified option available | HE3 suffix variants meet automotive qualification for engine control and ADAS power domains |
Applications

IC Role / Device Role / Timing Role: Secondary-level TVS on analog front-end inputs after isolation barriers, guarding ADC reference and bias networks. Use Value: Sub-ns response prevents transient coupling into 24-bit sigma-delta converters, preserving diagnostic accuracy. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58A | Lower PPPM (600 W), SMC package (smaller footprint), 58.0–64.4 V VBR, 93.6 V VC @ 6.4 A | Targeted at space-constrained consumer electronics; insufficient for 1500 W IEC 61000-4-5 compliance | Select when board area is limited and surge energy is ≤600 W; verify clamping margin vs. protected IC's absolute max rating |
| 1.5KE56A | Same 1.5KE package, identical VBR/VC specs, but base P/N lacks E3/54 tape-and-reel packaging and RoHS documentation traceability | No AEC-Q101 or JESD 201 whisker testing; not suitable for automotive or medical production | Use only for prototyping or non-certified industrial builds; 1N6289-E3/54 provides full compliance documentation and lot traceability |
Compared with SMBJ58A and 1.5KE56A, the 1N6289-E3/54 uniquely combines full 1500 W surge handling, RoHS/E3/54 tape-and-reel logistics, and documented JESD 201 Class 1A whisker resistance - making it the only choice for volume automotive and certified medical designs requiring audit-ready sourcing.

FAQ
What is the exact breakdown voltage range for 1N6289-E3/54?
The 1N6289-E3/54 has a guaranteed breakdown voltage range of 53.2 V to 58.8 V at 1 mA test current per the Vishay datasheet (Document Number: 88301, Rev. 09-Aug-2022). This ±5 % tolerance ensures consistent clamping behavior across production lots and temperature extremes, directly supporting design margin calculations for 48 V system protection. The 1N6289-E3/54 achieves this specification using a glass-passivated silicon junction optimized for stability.
Does 1N6289-E3/54 meet automotive qualification standards?
The 1N6289-E3/54 itself is commercial-grade and RoHS-compliant (E3 suffix), but Vishay offers the AEC-Q101 qualified version as 1N6289AHE3_B in the same 1.5KE package. While the 1N6289-E3/54 shares identical electrical specs and thermal performance, it lacks the extended reliability testing required for automotive under-hood use. For production automotive designs, specify the HE3_B variant; the 1N6289-E3/54 remains ideal for industrial and telecom applications requiring full traceability and RoHS compliance.
What is the clamping voltage of 1N6289-E3/54 at its rated peak pulse current?
The 1N6289-E3/54 clamps to a maximum of 77.0 V at its rated peak pulse current of 19.5 A (10/1000 μs waveform). This value is measured per JEDEC standards and reflects the worst-case voltage imposed on protected circuitry during a full-power surge event. The low clamping ratio (VC/VBR ≈ 1.38) of the 1N6289-E3/54 ensures minimal let-through energy, critical for safeguarding 75 V-rated power MOSFETs and interface ICs without derating.
Can 1N6289-E3/54 be used in bidirectional configurations?
No - the 1N6289-E3/54 is strictly a unidirectional TVS diode, as indicated by the "A" suffix and absence of "CA" in its part number. Bidirectional operation requires the CA-suffixed variant (e.g., 1N6289CA), which has symmetrical clamping in both polarities. Using the 1N6289-E3/54 in AC or floating-rail applications risks catastrophic failure due to forward conduction during negative transients. Always match polarity designation to system grounding architecture when selecting the 1N6289-E3/54.
What packaging format does 1N6289-E3/54 ship in?
The 1N6289-E3/54 ships in 13-inch diameter paper tape and reel packaging with a base quantity of 1400 units per reel (ordering code "/54"). This format supports automated SMT placement via axial-lead feeders and includes full RoHS compliance documentation (E3 suffix), JESD 201 Class 1A whisker testing certification, and traceable lot data - essential for high-volume manufacturing and audit-ready quality systems using the 1N6289-E3/54.
