Product details
Overview
1N6288A-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 51 V breakdown voltage (VBR = 48.5–53.6 V at 1 mA), 1500 W peak pulse power (10/1000 µs), 70.1 V maximum clamping voltage at 21.4 A, 43.6 V stand-off voltage, and 1.0 µA max reverse leakage at VWM. It is widely used to protect MOSFETs, ICs, and sensor interfaces against ESD and inductive switching transients in industrial and automotive electronics.
For engineers reviewing the 1N6288A-E3/54 datasheet, 1N6288A-E3/54 pinout, 1N6288A-E3/54 application, or 1N6288A-E3/54 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, polarity marking guidance, clamping performance under surge conditions, and direct alternatives with documented functional trade-offs.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds its breakdown threshold, it avalanches rapidly (<1 ns response) to divert surge current away from downstream components. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, enabling consistent clamping across repetitive 10/1000 µs pulses at 0.01% duty cycle.
The device is rated for 175 °C maximum junction temperature and supports 200 A non-repetitive forward surge (8.3 ms half-sine). Its thermal resistance (RθJA = 75 °C/W, RθJL = 15.4 °C/W) and matte tin-plated leads compliant with J-STD-002 define its PCB-level thermal and solderability behavior in high-reliability assemblies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 48.5 V / 53.6 V at 1 mA - defines precise avalanche initiation window for reliable overvoltage detection |
| VWM | 43.6 V - maximum continuous working voltage before leakage rises above 1.0 µA |
| VC @ IPPM | 70.1 V at 21.4 A - clamping voltage during full 1500 W surge, limiting stress on protected ICs |
| PPPM | 1500 W (10/1000 µs) - peak transient energy absorption capacity without failure |
| IFSM | 200 A (8.3 ms half-sine) - single-pulse surge current rating for inductive load switching events |
| TJ range | –55 °C to +175 °C - enables operation in under-hood automotive and industrial ambient environments |
| Package | JEDEC DO-201AD (Case Style 1.5KE) - axial-leaded, epoxy-molded, UL 94 V-0 compliant housing |
Pinout & Package
1N6288A-E3/54 uses the standard axial DO-201AD package (Case Style 1.5KE), with cathode identified by a color band on one end. Leads are matte tin-plated and solderable per J-STD-002. The device has two terminals only: anode and cathode - no internal circuitry or additional pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Surge current sink node | Connected to protected line; conducts avalanche current to ground during overvoltage |
| Anode (unmarked end) | Reference/return path | Typically tied to system ground or low-impedance return plane for effective clamping |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures ±5% VBR tolerance and long-term stability under thermal cycling and humidity |
| 1500 W peak pulse power | Withstands lightning-induced surges (IEC 61000-4-5 Level 4) on 24 V/48 V industrial buses |
| <1 ns response time | Clamps transients before sensitive CMOS inputs or gate drivers experience damage |
| AEC-Q101 qualified option available | HE3 suffix variants meet automotive reliability requirements for engine control and body electronics |
| UL 94 V-0 molded epoxy case | Provides flame-retardant mechanical protection and creepage/clearance compliance in safety-critical designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ51A | DO-214AA package (SMB), lower PPPM = 600 W, same VBR range (48.5–53.6 V), higher IPPM = 12.3 A | Surface-mount footprint; better suited for space-constrained PCBs but lower surge margin | Select SMBJ51A when board area is limited and surge threat level is moderate (IEC 61000-4-2 Level 3) |
| 1.5KE51A | Same DO-201AD package and identical electrical specs; differs only in packaging format (tape-and-reel vs. bulk) and RoHS compliance code (E3/54 denotes 1400-piece paper tape) | No functional difference; identical performance and mounting | Choose 1.5KE51A for alternate ordering channels where part number formatting differs but device is physically and electrically identical |
Compared with 1N6288A-E3/54, SMBJ51A offers SMT compatibility at reduced surge capacity, while 1.5KE51A is a functionally identical variant with different packaging logistics-neither requires PCB redesign, but only 1.5KE51A guarantees identical mechanical and thermal behavior in through-hole layouts.

FAQ
What is the breakdown voltage tolerance of the 1N6288A-E3/54?
The 1N6288A-E3/54 has a specified breakdown voltage range of 48.5 V to 53.6 V at 1 mA test current, corresponding to a ±5% tolerance around the nominal 51 V rating. This tight tolerance ensures predictable clamping onset across production lots and temperature extremes, supporting robust overvoltage protection design without excessive derating.
Is the 1N6288A-E3/54 RoHS compliant and lead-free?
Yes, the 1N6288A-E3/54 is RoHS compliant and lead-free. The "E3" suffix explicitly indicates commercial-grade, RoHS-compliant construction with matte tin-plated leads that meet J-STD-002 solderability standards and JESD 201 Class 1A whisker testing requirements.
How does the 1N6288A-E3/54 compare to bidirectional TVS diodes like 1N6288CA?
The 1N6288A-E3/54 is unidirectional and intended for DC line protection with defined polarity; the 1N6288CA is bidirectional and suitable for AC or floating signal lines. They share identical VBR, VC, and PPPM, but the unidirectional version exhibits forward conduction below VBR, whereas the bidirectional type blocks in both directions until either polarity exceeds VBR.
What is the maximum clamping voltage of the 1N6288A-E3/54 under surge conditions?
The maximum clamping voltage (VC) of the 1N6288A-E3/54 is 70.1 V at 21.4 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value represents the upper limit of voltage seen by protected circuitry during a full 1500 W transient event, directly determining safe operating margins for downstream ICs.
Can the 1N6288A-E3/54 be used in automotive applications?
The base 1N6288A-E3/54 is commercial-grade; however, Vishay offers the AEC-Q101 qualified variant 1N6288AHE3_B (with HE3 suffix) for automotive use. That version undergoes extended reliability testing including temperature cycling, HTRB, and ESD per AEC-Q101, making it suitable for body electronics and infotainment systems-but the E3/54 version itself is not AEC-Q101 certified.
