Product details
Overview
1N6275-E3/73 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 1500 W peak pulse power rating (10/1000 µs), 14.3–15.8 V breakdown voltage at 1.0 mA test current, 12.8 V maximum standoff voltage, 1.0 µA max reverse leakage at VWM, and clamps to ≤21.2 V at 70.8 A peak pulse current. It is used in automotive power supply inputs and industrial sensor interface protection.
For engineers reviewing the 1N6275-E3/73 datasheet, 1N6275-E3/73 pinout, 1N6275-E3/73 application, or 1N6275-E3/73 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, clamping performance under surge conditions, thermal resistance data, and RoHS-compliant commercial-grade sourcing guidance - all specific to the 1N6275-E3/73 variant.
Technical Context
This device operates as a unidirectional avalanche diode with glass-passivated junction, optimized for fast transient suppression (<1 ns response). Its 1500 W peak pulse power rating is defined per 10/1000 µs waveform at 0.01% duty cycle, and it exhibits 0.084 %/°C temperature coefficient of VBR.
Clamping behavior is characterized by low incremental surge resistance and stable VC = 21.2 V at IPPM = 70.8 A. It supports operating junction temperatures from –55 °C to +175 °C and is rated for 200 A non-repetitive forward surge (8.3 ms half-sine).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 14.3 V / 15.8 V at 1.0 mA - defines reliable avalanche initiation threshold for overvoltage detection |
| VWM | 12.8 V - maximum continuous reverse working voltage before leakage exceeds 1.0 µA |
| IPPM | 70.8 A (10/1000 µs) - peak surge current it safely shunts without failure |
| VC @ IPPM | ≤21.2 V - clamped voltage seen by protected circuit during full-rated surge |
| PPPM | 1500 W - peak transient power dissipation capability under standardized surge waveform |
| RθJA | 75 °C/W - thermal resistance from junction to ambient, critical for PCB copper pour design |
| TJ range | –55 °C to +175 °C - enables use in under-hood automotive and industrial environments |
Pinout & Package
1N6275-E3/73 uses the standard axial-lead DO-201AD (JEDEC 1.5KE) package: molded epoxy body, matte tin-plated leads, RoHS-compliant, commercial grade. Cathode identified by color band on body end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry point in forward bias; connected to lower-potential side of protected line | Must be tied to ground or return path when used in unidirectional clamp configuration |
| Cathode (banded end) | Current exit point in forward bias; connected to higher-potential side of protected line | Placed on supply rail or signal line to be protected; absorbs positive transients to ground |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable, repeatable avalanche characteristics and long-term reliability under repeated surges |
| 1500 W peak pulse power (10/1000 µs) | Supports robust protection against IEC 61000-4-5 Level 4 surges (4 kV line-to-ground) in properly designed layouts |
| Fast <1 ns response time | Clamps transients before sensitive downstream ICs (e.g., microcontrollers, CAN transceivers) experience overstress |
| Low incremental clamping voltage (ΔVC = VC – VBR ≈ 6.9 V) | Minimizes voltage overshoot margin required in system-level protection coordination |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker resistance; suitable for lead-free reflow and wave soldering processes |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: 12 V battery-fed ECUs exposed to load dump (ISO 16750-2) and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and input filter capacitor to clamp positive surges to ≤21.2 V. Use Value: Prevents damage to upstream LDOs and downstream MCUs by limiting transient voltage within their absolute maximum ratings. |
Use Scenario: 4–20 mA current loop sensors in factory automation subject to ESD and inductive switching noise. IC Role / Device Role / Timing Role: TVS mounted across sensor output terminals to divert fast transients before reaching analog front-end op-amps. Use Value: Maintains signal integrity and prevents latch-up in precision ADC drivers during field wiring faults. |
| DC Power Supply Rail Protection | Telecom Interface Surge Protection |
Use Scenario: 24 V industrial PLC power inputs subjected to repetitive switching transients from relay coils and solenoids. IC Role / Device Role / Timing Role: Primary-stage TVS on main DC input, upstream of bulk capacitance and DC/DC converter. Use Value: Absorbs energy from 1500 W surges without degradation, enabling >100,000 surge events per MIL-STD-883H Class H life testing. |
Use Scenario: RS-485 transceiver ports in outdoor telecom cabinets exposed to induced lightning surges (IEC 61000-4-5). IC Role / Device Role / Timing Role: Unidirectional TVS on VCC line and bidirectional TVS pairs on differential bus lines (A/B). Use Value: Limits common-mode surge voltage to safe levels while preserving signal swing and timing margins for 10 Mbps operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A | Lower PPPM (600 W), smaller SMB package (lower RθJA = 40 °C/W), same VBR range (14.3–15.8 V) | Better suited for space-constrained PCBs with moderate surge exposure (IEC 61000-4-2/4-4); not rated for 1500 W IEC 61000-4-5 Level 4 | Select SMBJ15A only if layout area is limited and surge threat level is ≤Level 3; verify thermal derating at elevated ambient. |
| 1.5KE15A | Identical electrical specs and DO-201AD package; differs only in packaging format (tape-and-reel vs. bulk/ammopack) and traceability marking | No functional difference; both meet same Vishay specification 88301 and share identical qualification data | 1.5KE15A is direct form-fit-function replacement; choose based on logistics preference (E3/73 = 73 mm tape pitch, 1.5KE15A-E3/54 = 54 mm pitch). |
Compared with 1N6275-E3/73, SMBJ15A trades peak power headroom for compactness and thermal efficiency, while 1.5KE15A offers identical protection performance with alternate packaging - making the latter ideal for drop-in continuity in legacy designs requiring DO-201AD form factor.

FAQ
What is the breakdown voltage tolerance for 1N6275-E3/73?
The 1N6275-E3/73 has a specified breakdown voltage range of 14.3 V to 15.8 V at 1.0 mA test current, representing ±5% tolerance around the nominal 15 V rating. This tight VBR window ensures consistent clamping onset across production lots and supports predictable coordination with downstream overvoltage protection circuits.
Is 1N6275-E3/73 RoHS compliant and lead-free solder compatible?
Yes, the "E3" suffix in 1N6275-E3/73 indicates full RoHS compliance per Directive 2011/65/EU and compatibility with lead-free reflow and wave soldering processes. Its matte tin-plated leads meet J-STD-002 and JESD 22-B102 standards, and it passes JESD 201 Class 1A whisker testing for long-term interconnect reliability.
How does the clamping voltage of 1N6275-E3/73 compare to its breakdown voltage?
The 1N6275-E3/73 clamps to ≤21.2 V at its rated peak pulse current of 70.8 A (10/1000 µs), resulting in an incremental clamping voltage ΔVC = VC – VBR ≈ 6.9 V. This 46% overvoltage margin above VBR max is typical for 1500 W TVS devices and must be accounted for in protected IC absolute maximum voltage design margins.
Can 1N6275-E3/73 be used in bidirectional configurations?
No - 1N6275-E3/73 is a unidirectional TVS diode, identifiable by its cathode band. Bidirectional variants in the same family carry "CA" suffixes (e.g., 1.5KE15CA). Using 1N6275-E3/73 for AC or dual-polarity protection would require external series diode pairing and is not recommended due to asymmetry and reduced reliability.
What is the maximum operating temperature for 1N6275-E3/73?
The 1N6275-E3/73 has a maximum junction temperature (TJ) rating of +175 °C and operates reliably from –55 °C to +175 °C. At 100 °C ambient, its power derating requires limiting average dissipation to ~3.3 W (per Fig. 5), making it suitable for under-hood automotive and high-temperature industrial deployments when mounted with adequate copper thermal relief.
