Product details
Overview
1N6288AHE3_B/C from Vishay General Semiconductor is a unidirectional 1500 W transient voltage suppressor (TVS) diode with a breakdown voltage range of 48.5 V to 53.6 V at 1.0 mA test current, clamping voltage of 70.1 V at 21.4 A peak pulse current, and maximum stand-off voltage of 43.6 V. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power supply rails against lightning-induced surges and inductive switching transients.
For engineers reviewing the 1N6288AHE3_B/C datasheet, 1N6288AHE3_B/C pinout, 1N6288AHE3_B/C application, or 1N6288AHE3_B/C equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance data, JEDEC 1.5KE package dimensions, and real-world protection use cases - all confirmed from Vishay's official 88301 document revision 09-Aug-2022.
Technical Context
This unidirectional TVS diode uses a glass passivated silicon junction optimized for fast clamping response (<1 ns), low incremental surge resistance, and stable operation across -55 °C to +175 °C junction temperature. Its 10/1000 μs waveform rating supports 1500 W peak pulse power with 0.01 % duty cycle repeatability.
The device features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, meets UL 94 V-0 flammability rating, and carries HE3 suffix indicating RoHS compliance and AEC-Q101 qualification per note (2) in the Vishay 88301 datasheet.

IC Role / Device Role: Placed across sensor output and ground to absorb ESD and cable discharge events. Use Value: Low 1.0 μA leakage at 43.6 V prevents signal offset errors in precision 4–20 mA loops. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ51A | 600 W PPPM, DO-214AA package, VBR = 56.7–62.7 V, VC = 82.4 V @ 7.3 A | Lower power rating and higher clamping voltage reduce protection margin in high-energy surge environments | Select when board space is constrained and surge energy is limited to IEC 61000-4-5 Level 2 |
| 1.5KE51A-E3/54 | Same electrical specs but commercial-grade (non-AEC-Q101), E3 suffix only, same 1.5KE package | Lacks automotive qualification; unsuitable for under-hood or safety-critical systems | Choose for cost-sensitive industrial or consumer designs where AEC-Q101 is not required |
Compared with SMBJ51A and 1.5KE51A-E3/54, the 1N6288AHE3_B/C delivers higher surge robustness (1500 W vs. 600 W), tighter clamping (70.1 V vs. 82.4 V), and automotive-grade reliability - making it optimal for demanding power rail protection where failure risk must be minimized.

FAQ
What is the breakdown voltage tolerance of the 1N6288AHE3_B/C?
The 1N6288AHE3_B/C has a specified breakdown voltage range of 48.5 V to 53.6 V at 1.0 mA test current, corresponding to ±5.2% tolerance around the nominal 51 V rating. This tight VBR window ensures consistent clamping behavior across production lots and supports predictable overvoltage protection design in critical power rails.
Is the 1N6288AHE3_B/C suitable for automotive applications?
Yes, the 1N6288AHE3_B/C is AEC-Q101 qualified per Vishay document 88301 note (2), covering devices from 1.5KE6.8AHE3_B to 1.5KE220AHE3_B. Its construction, thermal rating (+175 °C TJ max), and qualification testing make it appropriate for engine control units, body electronics, and ADAS power domains where reliability under thermal and electrical stress is mandatory.
What does the "HE3_B/C" suffix mean in 1N6288AHE3_B/C?
The "HE3" suffix indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "B/C" denotes the revision code per Vishay's ordering nomenclature. The full part number 1N6288AHE3_B/C matches the preferred package code "C" (13" paper tape and reel, 1400 units per reel) as defined in the Vishay 88301 ordering information table.
How does the clamping voltage of the 1N6288AHE3_B/C compare to its breakdown voltage?
The 1N6288AHE3_B/C clamps at 70.1 V when subjected to its rated 21.4 A peak pulse current (10/1000 μs waveform), which is approximately 37% above its minimum breakdown voltage of 48.5 V. This ΔV = 21.6 V headroom reflects the device's incremental surge resistance and confirms effective transient suppression without excessive voltage overshoot on protected circuits.
Can the 1N6288AHE3_B/C be used in bidirectional configurations?
No - the 1N6288AHE3_B/C is explicitly a unidirectional TVS diode, as indicated by its "A" suffix and absence of "CA" designation. Bidirectional variants (e.g., 1.5KE51CA) exist in the same family but require separate part numbers; using the 1N6288AHE3_B/C in bidirectional roles would result in forward conduction during negative transients and potential failure.
