Product details
Overview
1N6299-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It features a 1500 W peak pulse power rating (10/1000 µs), 143 V minimum breakdown voltage (VBR), 128 V maximum standoff voltage (VWM), 7.2 A peak pulse current (IPPM), and clamps transients to 207 V at rated current - deployed in automotive power supply inputs, industrial sensor interfaces, and telecom line protection.
For engineers reviewing the 1N6299-E3/73 datasheet, 1N6299-E3/73 pinout, 1N6299-E3/73 application, or 1N6299-E3/73 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, clamping performance under standardized surge waveforms, thermal derating behavior, and RoHS-compliant commercial-grade sourcing status.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector, triggering when reverse voltage exceeds its 143–158 V breakdown range (tested at 1 mA). Its glass-passivated junction enables sub-nanosecond response time and low incremental surge resistance, critical for safeguarding MOSFETs and ICs against lightning-induced surges and inductive switching transients.
Rated for 175 °C maximum junction temperature and 6.5 W steady-state power dissipation on infinite heatsink, it supports operation across –55 °C to +175 °C with 0.106 %/°C VBR temperature coefficient. The device complies with JESD22-B106 (275 °C solder dip) and JESD201 Class 1A whisker testing (E3 suffix).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 143 V / 158 V at 1 mA - defines precise clamping initiation threshold for overvoltage events |
| VWM | 128 V - maximum continuous reverse operating voltage before leakage exceeds 1 μA |
| IPPM | 7.2 A at 10/1000 µs waveform - peak transient current it safely diverts without failure |
| VC | 207 V at IPPM - clamped voltage seen by protected circuit during full-rated surge |
| PPPM | 1500 W - energy-handling capacity for standardized 1 ms surge pulses |
| TJ max. | +175 °C - enables reliable operation in under-hood automotive and industrial ambient environments |
| RθJA | 75 °C/W - thermal resistance from junction to ambient, informs heatsinking requirements |
Pinout & Package
Package: JEDEC DO-201AD (Case Style 1.5KE), axial-leaded molded epoxy body with matte tin-plated leads; RoHS-compliant E3 suffix; 0.968 g unit weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Use Scenario: 12 V battery-fed ECUs exposed to load dump transients up to 120 V for 400 ms. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between VBAT and GND, clamping surges before they reach LDOs and microcontrollers. Use Value: Limits voltage to ≤207 V during 7.2 A surge, preventing latch-up or gate oxide rupture in downstream PMICs and MCUs. |
Use Scenario: 4–20 mA current loop transmitters in factory automation subject to ESD and cable-coupled noise. IC Role / Device Role / Timing Role: TVS mounted across loop terminals to clamp fast-rising transients while maintaining <1 μA leakage at 128 V. Use Value: Preserves analog accuracy by limiting clamping voltage to 207 V with no forward conduction during normal operation. |
| Telecom DC Power Feeds | Consumer Power Adapter Output Rails |
|
Use Scenario: -48 V DC distribution in central office equipment vulnerable to lightning-induced surges on long copper runs. IC Role / Device Role / Timing Role: Unidirectional TVS referenced to system ground, absorbing common-mode surges coupled onto power pairs. Use Value: Handles 1500 W pulses without degradation, enabling compliance with ITU-T K.20 and Telcordia GR-1089-CORE. |
Use Scenario: Secondary-side 5–24 V outputs of AC/DC adapters subjected to user-induced ESD and plug-in surges. IC Role / Device Role / Timing Role: Low-leakage (≤1 μA at 128 V) TVS placed across output capacitor to suppress fast transients before reaching USB ports or charging ICs. Use Value: Prevents false resets or brownouts in connected devices by clamping spikes within 1 ns while drawing negligible quiescent current. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150A | DO-214AA package; 150 V VWM; 243 V VC at 6.2 A; 600 W PPPM | Lower power rating and higher clamping voltage; suited for space-constrained PCBs where 1500 W is not required | Select SMBJ150A only if board layout prohibits axial DO-201AD placement and surge energy remains below 600 W |
| 1.5KE150A | Same 1.5KE package and identical electrical specs; differs only in packaging format (bulk vs. tape-and-reel E3/73) | No functional difference; same thermal and clamping performance; identical qualification level (commercial grade) | 1.5KE150A is functionally identical to 1N6299-E3/73 and may be used interchangeably when reel packaging is not required |
Compared with SMBJ150A, 1N6299-E3/73 delivers 2.5× higher surge power handling and 36 V lower clamping voltage, making it superior for automotive and industrial applications with stringent energy requirements; versus 1.5KE150A, it offers identical protection performance with optimized tape-and-reel logistics for SMT assembly.

FAQ
What is the breakdown voltage range of the 1N6299-E3/73?
The 1N6299-E3/73 has a minimum breakdown voltage (VBR) of 143 V and a maximum of 158 V, measured at 1 mA test current per the Vishay 88301 datasheet. This tight 15 V window ensures predictable clamping onset across production lots and temperature ranges, critical for protecting 120 V nominal systems without premature conduction.
Is the 1N6299-E3/73 RoHS compliant and qualified for automotive use?
The 1N6299-E3/73 carries the E3 suffix, confirming RoHS compliance and JESD201 Class 1A whisker resistance, but it is a commercial-grade part - not AEC-Q101 qualified. For automotive applications requiring qualification, Vishay offers the 1.5KE150AHE3_B variant; the 1N6299-E3/73 remains suitable for non-safety-critical automotive subsystems where full qualification is not mandated.
What is the clamping voltage of the 1N6299-E3/73 at its rated peak pulse current?
At its rated peak pulse current of 7.2 A (10/1000 µs waveform), the 1N6299-E3/73 clamps to a maximum of 207 V. This value - specified as VC in the datasheet - represents the worst-case voltage imposed on the protected circuit during full-rated surge events, directly informing system-level overvoltage margin design.
Can the 1N6299-E3/73 be used in bidirectional configurations?
No - the 1N6299-E3/73 is a unidirectional TVS diode, identifiable by its cathode band marking and specified VBR/VWM values for reverse polarity only. Bidirectional variants (e.g., 1N6299CA) exist in the same family but are distinct orderable parts; substituting 1N6299-E3/73 in bidirectional roles risks forward conduction and failure during AC or dual-polarity transients.
What is the thermal resistance and maximum junction temperature of the 1N6299-E3/73?
The 1N6299-E3/73 has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and a maximum junction temperature (TJ) of +175 °C. These values define its safe operating area under sustained power dissipation and enable thermal design validation using Vishay's Fig. 5 derating curve - critical for high-temperature environments like engine compartments or enclosed industrial enclosures.
