Product details
Overview
1N6299A-E3/54 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), 143–158 V breakdown voltage range, 128 V maximum standoff voltage, 7.2 A peak pulse current, and clamps to 207 V at rated surge. It is used in automotive power supply inputs and industrial sensor interface protection.
For engineers reviewing the 1N6299A-E3/54 datasheet, 1N6299A-E3/54 pinout, 1N6299A-E3/54 application, or 1N6299A-E3/54 equivalent, key selection criteria include clamping voltage margin vs. protected IC's absolute maximum rating, thermal derating above 25 °C, unidirectional polarity marking, and compatibility with JEDEC 1.5KE package reflow and soldering profiles.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, delivering fast sub-nanosecond response to transient events. Its unidirectional configuration uses a cathode band for polarity identification and exhibits low incremental surge resistance to maintain tight clamping under high-current transients.
The 1N6299A-E3/54 is rated for 175 °C maximum junction temperature and supports repetitive surges at ≤0.01% duty cycle. Its thermal resistance is 75 °C/W (junction-to-ambient) and 15.4 °C/W (junction-to-lead), enabling effective heat dissipation when mounted on PCB copper pours or leads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 143–158 V at 1 mA test current - defines minimum voltage at which avalanche conduction begins, critical for margin against protected circuit's max rating |
| Standoff Voltage VWM | 128 V - maximum continuous reverse working voltage before leakage exceeds 1 μA; sets upper limit for normal operating rail |
| Clamping Voltage VC | 207 V at 7.2 A IPPM - actual voltage seen by downstream circuit during full-rated 10/1000 µs surge; determines protection headroom |
| Peak Pulse Power | 1500 W (10/1000 µs) - energy-handling capability for lightning or inductive-switching transients per industry standard waveform |
| Junction Temperature | -55 to +175 °C - enables operation in under-hood automotive and industrial environments without derating below -40 °C |
| Package | JEDEC 1.5KE - axial-leaded, molded epoxy case with UL 94 V-0 flammability rating; compatible with through-hole assembly and manual rework |
Pinout & Package
Package: JEDEC 1.5KE - axial-leaded, cylindrical molded epoxy body (diameter 5.3 mm, length 9.5 mm), matte tin-plated leads, RoHS-compliant (E3 suffix), rated for solder dip up to 275 °C for 10 s.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected line; conducts only during forward surge or bias conditions |
| Cathode (banded end) | Avalanche clamping terminal | Connected to higher-potential side (e.g., VIN); initiates clamping when reverse voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable, repeatable avalanche characteristics over lifetime and temperature; eliminates surface degradation risks |
| 1500 W peak pulse power | Supports IEC 61000-4-5 Level 4 (4 kV) surge immunity when properly laid out with low-inductance paths |
| Sub-nanosecond response time | Clamps transients before sensitive ICs experience overstress - critical for protecting MOSFET gates and MCU I/O |
| Low incremental surge resistance | Maintains predictable VC across varying surge amplitudes; reduces risk of secondary overvoltage overshoot |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker resistance; suitable for commercial-grade high-reliability industrial applications |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: 12 V battery-fed ECUs exposed to load dump (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Primary clamping device placed between battery rail and input filter capacitor; absorbs >95% of surge energy before it reaches LDO or MCU. Use Value: Clamps to 207 V while limiting peak current to 7.2 A - keeps downstream 36 V-rated input stages within safe operating area. | Use Scenario: 4–20 mA current loop transmitter connected to field wiring subject to induced lightning surges. IC Role / Device Role / Timing Role: Unidirectional TVS placed across loop terminals (anode to return, cathode to signal); shunts surge away from op-amp input stage. Use Value: 128 V standoff ensures no conduction during normal 24 V loop operation; 207 V clamping protects 30 V absolute-max op-amps. |
| Telecom DC Power Feeds | Consumer Appliance Motor Drive Inputs |
Use Scenario: -48 V telecom rectifier outputs feeding backplane distribution, subject to hot-swap and cable discharge events. IC Role / Device Role / Timing Role: Reverse-biased TVS on output rail; activated only during positive-going transients exceeding VBR. Use Value: 158 V max VBR provides 110 V margin above nominal -48 V rail, enabling robust protection without false triggering. | Use Scenario: AC/DC SMPS input stage in washing machine control board, exposed to relay contact bounce and motor commutation noise. IC Role / Device Role / Timing Role: TVS across bulk capacitor terminals to suppress repetitive 600–1000 V spikes from inductive kickback. Use Value: 1500 W rating sustains repeated 10/1000 µs surges at 0.01% duty cycle - extends system MTBF in high-noise environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150A | DO-214AA package; 150 V VBR min, 219 V VC at 6.8 A; 600 W rating | Lower power handling; surface-mount only; requires PCB layout optimization for thermal relief | Select when space-constrained designs prioritize SMT assembly and 600 W suffices for expected threat level |
| 1.5KE150A | Same electrical specs and JEDEC 1.5KE package; identical VBR, VC, and PPPM; differs only in ordering suffix (no -E3/54 tape/reel code) | No functional difference; same mechanical and thermal behavior; fully interchangeable in circuit design | Choose when standard bulk packaging (not 13" reel) or non-RoHS compliance is acceptable |
Compared with SMBJ150A, the 1N6299A-E3/54 delivers 2.5× higher surge power in a through-hole package ideal for high-energy industrial transients; compared with 1.5KE150A, it adds RoHS compliance, JESD 201 Class 1A whisker resistance, and optimized tape-and-reel logistics for automated assembly.

FAQ
What is the breakdown voltage tolerance of the 1N6299A-E3/54?
The 1N6299A-E3/54 has a specified breakdown voltage (VBR) range of 143 V to 158 V at 1 mA test current, representing ±5% tolerance around the nominal 150 V rating. This tolerance is measured per JEDEC standards and remains stable across temperature and lifetime under recommended operating conditions.
Does the 1N6299A-E3/54 support bidirectional transient suppression?
No, the 1N6299A-E3/54 is a unidirectional TVS diode. Its cathode band indicates polarity, and it clamps only in reverse bias. For bidirectional protection, Vishay offers the 1N6299CA variant (or 1.5KE150CA), which lacks polarity marking and suppresses transients in both directions.
What is the maximum allowable lead temperature during soldering for the 1N6299A-E3/54?
The 1N6299A-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 and JESD 22-B102 for solderability. Reflow profiles must stay within JEDEC J-STD-020 limits for plastic packages to avoid internal delamination.
How does thermal derating affect the 1N6299A-E3/54's peak pulse power capability?
The 1N6299A-E3/54's 1500 W peak pulse power is rated at TA = 25 °C. Above that, power must be linearly derated per Fig. 2 in the datasheet: at 75 °C ambient, maximum PPPM drops to ~1125 W; at 125 °C, it falls to ~750 W. Derating ensures junction temperature stays ≤175 °C during surge events.
Is the 1N6299A-E3/54 qualified to AEC-Q101 for automotive use?
No, the 1N6299A-E3/54 is commercial-grade only. AEC-Q101 qualification applies to variants with HE3 suffix (e.g., 1.5KE150AHE3_B). The E3 suffix confirms RoHS compliance and JESD 201 Class 1A whisker resistance but does not imply automotive stress testing or qualification.
