Product details
Overview
1N6299-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage 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), and clamps transients to ≤207 V at 7.2 A peak pulse current - deployed in automotive power supplies, industrial sensor interfaces, and telecom line cards.
For engineers reviewing the 1N6299-E3/54 datasheet, 1N6299-E3/54 pinout, 1N6299-E3/54 application, or 1N6299-E3/54 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, clamping behavior under surge conditions, thermal derating curves, and direct alternative options for circuit protection redesigns.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, delivering sub-nanosecond response time (<1 ns) to transient overvoltages. Its unidirectional polarity uses a cathode band marking and exhibits 3.5 V forward voltage at 100 A surge, with thermal resistance of 15.4 °C/W (junction-to-lead) and 75 °C/W (junction-to-ambient).
The 1N6299-E3/54 complies with JEDEC case style 1.5KE, supports 0.01% duty cycle repetitive surges, and is rated for -55 °C to +175 °C operating junction temperature. It is RoHS-compliant (E3 suffix), meets JESD 201 Class 1A whisker test, and is not AEC-Q101 qualified - unlike HE3-suffix variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 143 V / 158 V at 1 mA test current - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| VWM | 128 V maximum - ensures stable operation below clamping threshold during normal DC bias |
| VC @ IPPM | ≤207 V at 7.2 A - actual clamped voltage during 10/1000 µs surge, critical for downstream IC survivability |
| PPPM | 1500 W - peak transient energy absorption capability without failure under standardized lightning-surge waveform |
| IFSM | 200 A - maximum non-repetitive forward surge current (8.3 ms half-sine), supports high-energy fault clearing |
| TJ max | +175 °C - enables use in under-hood automotive or high-temperature industrial enclosures |
| RθJL | 15.4 °C/W - low junction-to-lead thermal resistance allows effective 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. Dimensions: 0.190–0.210" diameter × 0.285–0.375" length (4.8–5.3 mm × 7.2–9.5 mm). Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., GND or return path); conducts during reverse-transient clamping |
| Cathode | Avalanche breakdown terminal | Marked end; connected to protected line (e.g., +12 V rail); initiates clamping when voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures long-term stability and low leakage (<1 µA at VWM) across temperature and lifetime |
| 1500 W peak pulse power (10/1000 µs) | Withstands IEC 61000-4-5 Level 4 surges (4 kV, 2 Ω source) without degradation |
| Sub-nanosecond response time | Clamps transients before sensitive logic or analog circuits experience overstress (tr < 1 ns) |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (dV/dt > 100 V/ns) |
| UL 497B recognized (QVGQ2) | Validated for telecom and industrial surge protection systems requiring safety agency approval |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Clamp |
|---|---|
Use Scenario: Protects 12 V/24 V battery-fed ECUs against load dump (ISO 16750-2) and alternator switching transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground; clamps spikes within 1 ns to limit voltage seen by MCU power pins. Use Value: Maintains VCC below 207 V during 1500 W surges, preventing latch-up or gate oxide rupture in automotive-grade microcontrollers. |
Use Scenario: Shields 4–20 mA current-loop transmitters and analog front-ends from ESD and inductive kickback in factory automation. IC Role / Device Role / Timing Role: Mounted across input terminals of op-amp-based signal conditioners; absorbs ±8 kV HBM ESD per IEC 61000-4-2. Use Value: Limits transient voltage to ≤207 V while adding <1 pF capacitance, preserving bandwidth of 100 kHz sensor signals. |
| Telecom Line Card Surge Suppression | DC Power Supply Input Stage Clamp |
Use Scenario: Installed on POTS or xDSL line interfaces to meet GR-1089-CORE and ITU-T K.20 immunity requirements. IC Role / Device Role / Timing Role: Primary protection element upstream of gas discharge tube (GDT) and series impedance; handles fast-rising lightning-induced surges. Use Value: Clamps 10/1000 µs surges to ≤207 V before secondary protection activates, reducing stress on downstream MOVs and ICs. |
Use Scenario: Used at AC/DC converter input to suppress differential-mode surges from mains transients and capacitor-switching events. IC Role / Device Role / Timing Role: Placed across bulk capacitor terminals in offline SMPS; diverts surge energy away from rectifier bridge and controller IC. Use Value: Absorbs 1500 W peak power without thermal runaway, enabling compact design versus multi-stage protection schemes. |
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 (SMB), 1500 W rating, VBR = 167–185 V, VC = 243 V @ 6.2 A | Surface-mount footprint; higher clamping voltage (+36 V vs. 1N6299-E3/54) reduces margin for 150 V-rated circuits | Select when board space is constrained and PCB layout supports SMT; verify clamping headroom for protected ICs. |
| 1.5KE150A | Identical electrical specs and 1.5KE package; differs only in packaging format (E3/54 = tape-and-reel; standard 1.5KE150A may be bulk or different reel) | No functional or performance difference; same thermal and surge characteristics | Direct form-fit-function replacement if sourcing flexibility or alternate delivery mode (e.g., bulk vs. tape) is required. |
Compared with 1N6299-E3/54, SMBJ150A trades axial-leaded robustness and lower clamping for SMT compatibility, while 1.5KE150A offers identical protection performance in alternate packaging - enabling supply chain redundancy without circuit redesign.

FAQ
What is the breakdown voltage tolerance for 1N6299-E3/54?
The 1N6299-E3/54 has a specified breakdown voltage range of 143 V to 158 V at 1 mA test current, representing a ±5% tolerance around the nominal 150 V rating. This tight VBR window ensures consistent clamping onset across production lots and supports predictable overvoltage protection margins in safety-critical designs.
Is 1N6299-E3/54 AEC-Q101 qualified?
No, the 1N6299-E3/54 is not AEC-Q101 qualified. It carries the E3 suffix indicating RoHS compliance and JESD 201 Class 1A whisker resistance, but lacks automotive qualification. For AEC-Q101 applications, engineers should select the HE3-suffix variant (e.g., 1.5KE150AHE3_B), which is explicitly certified per AEC-Q101 Rev D.
What is the maximum clamping voltage of 1N6299-E3/54 under surge conditions?
The 1N6299-E3/54 clamps to a maximum of 207 V when subjected to its rated 7.2 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is guaranteed across temperature and represents the upper bound of voltage imposed on protected circuitry during worst-case transient events.
Can 1N6299-E3/54 be used in bidirectional configurations?
No, 1N6299-E3/54 is strictly unidirectional. Bidirectional variants in the same family use the "CA" suffix (e.g., 1.5KE150CA). Using 1N6299-E3/54 in AC or symmetrical surge environments would result in forward conduction during negative half-cycles, causing failure. Always match polarity suffix to system topology.
What is the thermal resistance and how does it affect PCB layout for 1N6299-E3/54?
The 1N6299-E3/54 has a junction-to-lead thermal resistance (RθJL) of 15.4 °C/W. To maintain safe operation under repetitive surges, PCB traces connected to its leads must provide low-thermal-resistance paths - typically ≥25 mm² of 2 oz copper per lead - to dissipate heat and prevent junction temperature exceeding +175 °C.
