Product details
Overview
1N6276A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 16.8 V maximum breakdown voltage (VBR), 13.6 V working peak reverse voltage (VWM), 22.5 V clamping voltage (VC) at 66.7 A peak pulse current, 1500 W peak pulse power rating (10/1000 µs), and operates across -55 °C to +175 °C junction temperature range - deployed in automotive power supply inputs and industrial sensor interface protection.
For engineers reviewing the 1N6276A-E3/54 datasheet, 1N6276A-E3/54 pinout, 1N6276A-E3/54 application, or 1N6276A-E3/54 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, clamping performance under standardized surge waveforms, thermal resistance data, and direct alternative part comparisons - all validated against Vishay Document #88301 (Rev. 09-Aug-2022).
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its clamping behavior is characterized by a 22.5 V maximum VC at IPPM = 66.7 A (10/1000 µs waveform), with a temperature coefficient of VBR at +0.086 %/°C - ensuring stable threshold drift over temperature.
The device complies with JEDEC case style 1.5KE, supports 200 A non-repetitive forward surge current (IFSM), and exhibits 3.5 V maximum forward voltage at 100 A. Its thermal design relies on RθJL = 15.4 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient), enabling robust operation without heatsinking in moderate-power applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 15.2 V / 16.8 V - defines precise breakdown onset window for reliable triggering above normal operating voltage |
| VWM | 13.6 V - maximum continuous reverse voltage before leakage exceeds 1.0 µA, sets safe DC operating margin |
| VC @ IPPM | 22.5 V at 66.7 A - clamping voltage during 10/1000 µs surge, determines protected circuit's maximum stress level |
| PPPM | 1500 W - peak pulse power handling capability, enables suppression of high-energy transients like ISO 7637-2 Pulse 5a |
| IFSM | 200 A - single half-sine surge current rating (8.3 ms), supports robustness against inductive switch-off events |
| TJ range | -55 °C to +175 °C - extended junction temperature range allows use in under-hood automotive and industrial environments |
| RθJL | 15.4 °C/W - low junction-to-lead thermal resistance enables efficient heat transfer to PCB copper or heatsink |
Pinout & Package
Package: JEDEC-standard 1.5KE molded epoxy case (Case Style 1.5KE), axial-leaded, RoHS-compliant matte tin-plated leads. Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected line; conducts during positive transients when cathode is biased higher |
| Cathode | Reverse-biased clamping terminal | Marked with color band; connected to higher-potential rail (e.g., VIN); initiates avalanche breakdown during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable long-term reliability and low leakage (<1 µA at VWM) across temperature and humidity stress |
| 1500 W peak pulse power (10/1000 µs) | Supports EN 61000-4-5 Level 4 (4 kV) surge immunity without derating in typical PCB layouts |
| Clamping response time <1 ns | Protects fast-edge logic and analog front-ends before transient energy couples into sensitive ICs |
| AEC-Q101 qualification option (HE3 suffix) | Validated for automotive powertrain and body electronics per stress test requirements (not applicable to E3/54 variant) |
| UL 94 V-0 compliant molding compound | Meets flammability safety requirement for enclosed industrial and transportation equipment |
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 alternator ripple. IC Role / Device Role / Timing Role: Primary crowbar-style overvoltage clamp placed between VBAT and ground, triggered within nanoseconds. Use Value: Limits input rail to ≤22.5 V during 1500 W surges, preventing damage to downstream LDOs and microcontrollers. |
Use Scenario: 4–20 mA current loop interfaces in PLC analog I/O modules subject to field wiring ESD and inductive kick. IC Role / Device Role / Timing Role: Unidirectional shunt protector on signal line, referenced to system ground. Use Value: Clamps induced transients to 22.5 V while maintaining <1 µA leakage at 13.6 V, preserving loop accuracy. |
| Telecom DC Power Feeds | Consumer Appliance Motor Drive Inputs |
Use Scenario: -48 V telecom rectifier outputs feeding switching converters, vulnerable to lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: Reverse-polarity-protected TVS on output rail, oriented anode-to-rail for negative-voltage systems. Use Value: Withstands repetitive 10/1000 µs pulses up to 1500 W, meeting Telcordia GR-1089-CORE Level 3 requirements. |
Use Scenario: AC motor drive boards where relay coil de-energization induces >100 V spikes on control logic supply rails. IC Role / Device Role / Timing Role: Localized clamp on 5 V/3.3 V regulator input, placed adjacent to switching node. Use Value: Fast <1 ns response prevents latch-up in MCU GPIOs; 13.6 V VWM ensures no interference during nominal 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 |
|---|---|---|---|
| SMBJ16A | DO-214AA package, 16.7 V VBR min, 28.8 V VC @ 43.5 A, 600 W PPPM | Lower power rating and higher clamping voltage; suited for space-constrained PCBs where 1500 W is not required | Select SMBJ16A when board area is limited and surge threat level is ≤Level 3 (IEC 61000-4-5) |
| 1.5KE16A | Same 1.5KE package, identical VBR/VWM/VC specs, but E3/54 tape-and-reel packaging differs from standard bulk/E3 variants | No functional difference; identical electrical and thermal performance; only packaging and reel quantity differ | Choose 1.5KE16A for standard reel delivery (1400 pcs/reel) if automated assembly requires consistent tape format |
Compared with 1N6276A-E3/54, SMBJ16A offers smaller footprint but sacrifices 60% peak power and clamps 28% higher, making it less suitable for automotive load dump; 1.5KE16A is electrically identical but supplied in alternate tape configuration - ideal for production continuity when E3/54 reels are unavailable.

FAQ
What is the breakdown voltage tolerance for 1N6276A-E3/54?
The 1N6276A-E3/54 has a specified breakdown voltage range of 15.2 V (minimum) to 16.8 V (maximum) at 1.0 mA test current (IT), yielding ±5.3% tolerance around the nominal 16.0 V midpoint. This tight VBR window ensures predictable turn-on behavior across manufacturing lots and temperature extremes, critical for coordinating with upstream regulators and downstream IC absolute maximum ratings.
Is 1N6276A-E3/54 RoHS compliant and lead-free?
Yes, the 1N6276A-E3/54 carries the "E3" suffix, indicating full RoHS compliance per Directive 2011/65/EU and JESD 201 Class 1A whisker testing. Its matte tin-plated leads meet J-STD-002 solderability standards, and the molded epoxy body satisfies UL 94 V-0 flammability requirements - confirmed in Vishay Document #88301, Revision 09-Aug-2022.
What is the maximum clamping voltage of 1N6276A-E3/54 under surge conditions?
The 1N6276A-E3/54 exhibits a maximum clamping voltage (VC) of 22.5 V when subjected to its rated peak pulse current of 66.7 A using the standardized 10/1000 µs waveform. This value is measured per Figure 7 in Vishay Document #88301 and represents the upper bound of voltage seen by protected circuitry during worst-case transient events.
Can 1N6276A-E3/54 be used in bidirectional configurations?
No, the 1N6276A-E3/54 is strictly a unidirectional TVS diode, as indicated by the "A" suffix and absence of "CA" designation. Bidirectional variants (e.g., 1N6276CA) exist in the same family but feature symmetrical breakdown in both polarities - using 1N6276A-E3/54 in reverse-biased mode beyond VWM will cause irreversible avalanche conduction and failure.
What is the thermal resistance from junction to ambient for 1N6276A-E3/54?
The 1N6276A-E3/54 has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W under standard test conditions (free-air, 25 °C ambient). This value assumes no heatsinking; actual thermal performance improves significantly with PCB copper pour or lead-frame thermal relief - RθJL is 15.4 °C/W, confirming efficient conduction through the leads.
