Product details
Overview
1N6301-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 170 V breakdown voltage (VBR min/max: 162–179 V), 145 V stand-off voltage (VWM), 234 V clamping voltage at 6.4 A peak pulse current, 1500 W peak pulse power (10/1000 µs), and operates across –55 °C to +175 °C junction temperature. It protects MOSFETs, ICs, and sensor interfaces in industrial power supplies and automotive ECUs.
For engineers reviewing the 1N6301-E3/54 datasheet, 1N6301-E3/54 pinout, 1N6301-E3/54 application, or 1N6301-E3/54 equivalent, key selection criteria include verified clamping performance under 10/1000 µs transients, unidirectional polarity with cathode band marking, JEDEC 1.5KE package compatibility, and RoHS-compliant matte tin-plated leads meeting J-STD-002 solderability.
Technical Context
This TVS diode uses a glass passivated silicon junction optimized for fast response (<1 ns) and low incremental surge resistance. Its unidirectional configuration provides reverse-biased clamping only, with forward conduction limited to 3.5 V at 100 A - critical for protecting downstream rectifiers and gate drivers during positive-going surges.
The device adheres to JEDEC case style 1.5KE, rated for 1500 W peak pulse power at 25 °C ambient, derating linearly above 25 °C per Fig. 2, and supports repetitive surge duty cycles up to 0.01 % - making it suitable for infrequent but high-magnitude events like inductive load switching or lightning-induced transients on 24 V DC bus lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 162 V / 179 V - ensures reliable triggering above normal 145 V operating rail while avoiding false clamping |
| VWM | 145 V - maximum continuous reverse voltage before leakage exceeds 1 μA, compatible with 125 V nominal systems |
| VC @ IPPM | 234 V - clamped voltage at 6.4 A peak pulse, limiting stress on protected 200 V-rated MOSFETs |
| PPPM | 1500 W - handles 10/1000 µs surges up to 6.4 A without degradation, validated per REA P.E. 60 |
| IFSM | 200 A - withstands 8.3 ms half-sine surge, enabling use in motor drive snubbers and relay coil suppression |
| TJ max | +175 °C - supports operation in under-hood automotive environments and sealed industrial enclosures |
| RθJA | 75 °C/W - requires minimal heatsinking when mounted on 1-in² copper pour, simplifying PCB layout |
Pinout & Package
Package: JEDEC 1.5KE molded epoxy case (Case Style 1.5KE), axial leaded, RoHS-compliant matte tin plating, UL 94 V-0 rated molding compound. Cathode identified by color band.

Applications
| Industrial Power Supply Protection | Automotive ECU Input Protection |
|---|---|
Use Scenario: 24 V DC input stage of programmable logic controller (PLC) exposed to relay contact bounce and field wiring inductance. IC Role / Device Role: Unidirectional TVS placed between 24 V rail and chassis ground to clamp negative-going transients and limit positive excursions. Use Value: Clamps 10/1000 µs surges to ≤234 V, preventing latch-up in 200 V-rated buck controller ICs and preserving 10-year field reliability. | Use Scenario: CAN transceiver power input in engine control unit subjected to load dump per ISO 7637-2 Pulse 5a (75 V, 400 ms). IC Role / Device Role: Primary overvoltage clamp upstream of LDO regulator, absorbing energy before downstream filtering stages. Use Value: Withstands 200 A non-repetitive forward surge (IFSM) and maintains VC < 250 V during 60 V transient, ensuring regulator input stays within safe operating area. |
| MOSFET Gate Driver Protection | Sensor Signal Line Clamp |
Use Scenario: High-side N-channel MOSFET driver in 48 V battery management system experiencing shoot-through induced spikes. IC Role / Device Role: TVS placed between gate and source to suppress dv/dt-induced Miller turn-on and gate oxide overstress. Use Value: Low clamping voltage (234 V) and fast response (<1 ns) prevent gate-source voltage from exceeding 20 V rating of driver IC, avoiding catastrophic failure. | Use Scenario: Analog output line of pressure sensor in HVAC control panel exposed to ESD and nearby motor switching noise. IC Role / Device Role: Series-connected TVS on 0–5 V output line, referenced to signal ground, limiting excursion beyond ADC input range. Use Value: 145 V stand-off allows full 5 V signal swing while clamping 8/20 µs ESD events to <10 V, preserving 12-bit measurement accuracy. |
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, 170 V VBR, 231 V VC @ 6.5 A, 600 W PPPM | Lower peak power rating limits use to lower-energy transients; surface-mount only | Select when board space is constrained and surge energy is ≤600 W (e.g., consumer IoT sensors) |
| 1.5KE170A | Same electrical specs and 1.5KE package; differs only in part numbering convention (JEDEC vs. manufacturer prefix) | No functional difference; identical pinout, thermal profile, and reliability data | Direct form-fit-function replacement; preferred for legacy BOM alignment where 1.5KE prefix is specified |
Compared with SMBJ170A, 1N6301-E3/54 delivers 2.5× higher surge energy handling in the same axial-leaded footprint; versus 1.5KE170A, it shares identical performance but carries Vishay's commercial-grade E3 suffix and 13" tape-and-reel packaging (54 per reel), simplifying procurement for high-volume production.

FAQ
What is the breakdown voltage tolerance for 1N6301-E3/54?
The 1N6301-E3/54 has a specified breakdown voltage range of 162 V to 179 V at 1.0 mA test current, corresponding to a ±5 % tolerance around the nominal 170 V rating. This tight tolerance ensures predictable clamping behavior across production lots and temperature extremes from –55 °C to +175 °C, critical for maintaining safety margins in certified industrial equipment.
Is 1N6301-E3/54 suitable for automotive applications?
Yes - while the 1N6301-E3/54 itself is commercial grade, its identical-specification variant 1N6301AHE3_B is AEC-Q101 qualified for automotive use. The 1N6301-E3/54 shares the same glass passivated junction, thermal resistance (RθJL = 15.4 °C/W), and surge capability, making it suitable for non-safety-critical automotive subsystems such as body control modules when validated per customer requirements.
How does the clamping voltage of 1N6301-E3/54 compare to its breakdown voltage?
The 1N6301-E3/54 clamps at 234 V when subjected to its rated 6.4 A peak pulse current (10/1000 µs), which is 37 % above its minimum breakdown voltage of 162 V. This incremental clamping voltage (ΔVC = 72 V) reflects low dynamic impedance, enabling effective protection of 200 V-rated components without excessive voltage overshoot during fast-rising transients.
What is the maximum allowable lead temperature during soldering for 1N6301-E3/54?
The 1N6301-E3/54 supports solder dip at up to 275 °C for 10 seconds per JESD 22-B106, and its matte tin-plated leads comply with J-STD-002 for both wave and reflow soldering. For hand soldering, peak tip temperature should not exceed 350 °C for <3 seconds to avoid thermal stress on the glass passivated junction or epoxy body.
Can 1N6301-E3/54 be used in bidirectional configurations?
No - the 1N6301-E3/54 is strictly unidirectional, indicated by its "A" suffix and cathode band marking. Bidirectional variants (e.g., 1N6301CA) exist in the same family but differ in internal construction and polarity; substituting 1N6301-E3/54 in a bidirectional circuit will result in forward conduction during negative transients and loss of protection.
