Product details
Overview
1N6301A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary-side overvoltage protection in power rails and signal lines. It features a 162 V to 179 V breakdown voltage range (VBR), 145 V maximum working voltage (VWM), 234 V clamping voltage at 6.4 A peak pulse current, 1500 W peak pulse power rating (10/1000 µs), and operates across –55 °C to +175 °C junction temperature. It is used to protect MOSFETs and ICs against lightning-induced transients in industrial power supplies.
For engineers reviewing the 1N6301A-E3/54 datasheet, 1N6301A-E3/54 pinout, 1N6301A-E3/54 application, or 1N6301A-E3/54 equivalent, this page delivers verified electrical parameters, package dimensions, clamping behavior under surge conditions, thermal resistance data, and direct alternatives with documented functional differences - all specific to the 1N6301A-E3/54 variant.
Technical Context
This device implements a glass-passivated silicon PN junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its unidirectional polarity enables cathode-referenced clamping on positive-going surges only, with a 3.5 V forward voltage at 100 A per JEDEC spec.
The 1N6301A-E3/54 operates within a 75 °C/W junction-to-ambient thermal resistance (RθJA) and 15.4 °C/W junction-to-lead (RθJL), supporting reliable derating up to 175 °C maximum junction temperature. It complies with JESD 22-B106 solder dip (275 °C, 10 s) and JESD 201 Class 1A whisker testing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ170A | DO-214AA package; lower PPPM = 600 W; VBR = 189–209 V; VC = 275 V @ 2.2 A | Lower surge capacity suits secondary-side or low-energy signal-line use; not suitable for primary 1500 W surge duty. | Select SMBJ170A only when board space constraints prohibit axial 1.5KE form factor and surge energy is ≤600 W. |
| 1.5KE170A | Same 1.5KE package and identical electrical specs; differs only in packaging code (E3/54 vs. standard E3 tape-and-reel). | No functional difference; both meet same Vishay specification 88301 and share identical VBR, VC, and thermal ratings. | 1.5KE170A is functionally identical to 1N6301A-E3/54 and may be substituted where reel quantity (1400 pcs) or tape format matches design procurement needs. |
Compared with 1N6301A-E3/54, SMBJ170A offers smaller footprint but reduced surge margin, while 1.5KE170A provides identical protection performance in alternate packaging - enabling flexibility in volume procurement and layout reuse without electrical compromise.

FAQ
What is the breakdown voltage range of the 1N6301A-E3/54?
The 1N6301A-E3/54 has a specified breakdown voltage (VBR) range of 162 V to 179 V at 1.0 mA test current, per Vishay document 88301. This range ensures consistent clamping onset across production lots while maintaining margin above its 145 V maximum working voltage (VWM). The 1N6301A-E3/54 must be selected only where system operating voltage remains below 145 V to prevent premature conduction.
Is the 1N6301A-E3/54 RoHS compliant and qualified for automotive use?
The 1N6301A-E3/54 carries the E3 suffix, confirming RoHS compliance per EU Directive 2011/65/EU and material categorization per Vishay doc 99912. However, it is commercial-grade only - AEC-Q101 qualification applies only to HE3-suffix variants (e.g., 1.5KE170AHE3_B). Therefore, the 1N6301A-E3/54 is not AEC-Q101 qualified and should not be used in automotive safety-critical applications unless validated per customer-specific requirements.
What is the clamping voltage of the 1N6301A-E3/54 under surge conditions?
The 1N6301A-E3/54 exhibits a maximum clamping voltage (VC) of 234 V at its rated peak pulse current (IPPM) of 6.4 A, measured using the standard 10/1000 µs waveform. This value represents the upper limit of voltage seen by downstream components during worst-case surge events and is critical for ensuring protected ICs remain within their absolute maximum ratings. The 1N6301A-E3/54 achieves this with low incremental surge resistance, minimizing voltage overshoot.
Can the 1N6301A-E3/54 be used in bidirectional configurations?
No - the 1N6301A-E3/54 is a unidirectional TVS diode, indicated by the "A" suffix and absence of "CA" in its designation. Bidirectional variants (e.g., 1.5KE170CA) are available in the same family but have different internal construction and symmetrical clamping behavior. Using the 1N6301A-E3/54 in bidirectional applications would result in forward conduction on negative transients, potentially causing failure. Always verify polarity marking (cathode band) before placement.
What is the thermal resistance and maximum junction temperature of the 1N6301A-E3/54?
The 1N6301A-E3/54 has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and a maximum junction temperature (TJ) of +175 °C. Its junction-to-lead resistance (RθJL) is 15.4 °C/W, indicating efficient heat transfer to PCB copper or heatsinking leads. These values allow derating calculations per Figure 2 and Figure 5 in Vishay doc 88301, supporting reliable operation in sealed enclosures up to 85 °C ambient when mounted on ≥1 in² 2-oz copper.
