Product details
Overview
1N6299HE3/73 from Vishay General Semiconductor is a unidirectional 1500 W Transient Voltage Suppressor (TVS) diode with a nominal breakdown voltage of 143 V, clamping voltage of 207 V at 7.2 A peak pulse current, and 1.5KE package. It features glass passivated junction, AEC-Q101 qualification, and is designed for surge protection on power rails and signal lines in automotive and industrial electronics.
For engineers reviewing the 1N6299HE3/73 datasheet, 1N6299HE3/73 pinout, 1N6299HE3/73 application, or 1N6299HE3/73 equivalent, this page delivers verified electrical parameters, thermal resistance (RθJA = 75 °C/W), JEDEC-standard 10/1000 µs waveform performance, RoHS-compliant matte tin plating, and JESD 201 Class 2 whisker resistance - all critical for ESD/surge design validation and BOM continuity planning.
Technical Context
This device operates as a unidirectional avalanche diode, triggering at 143 V (min) to 158 V (max) breakdown under 1 mA test current, with stand-off voltage of 128 V and <1 µA reverse leakage at rated VWM. Its clamping response time is ≤1 ns, enabling protection of MOSFETs and ICs against lightning-induced transients per IEC 61000-4-5 and R.E.A. P.E. 60.
Thermal performance is defined by RθJL = 15.4 °C/W (junction-to-lead) and derated power dissipation above 25 °C ambient per Fig. 2; maximum junction temperature is +175 °C, supporting operation in under-hood automotive environments and industrial power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |

|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump transients up to 60 V for 400 ms. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power input and ground, clamping surges before they reach LDOs and microcontrollers. Use Value: Withstands 200 A surge (8.3 ms) and clamps to 207 V, preventing damage to downstream 3.3 V/5 V logic and analog front-ends. |
Use Scenario: Shielding 4–20 mA current loop inputs in PLC modules from field wiring induced surges. IC Role / Device Role / Timing Role: Series-connected TVS on loop supply line, absorbing energy from inductive kickback and lightning coupling. Use Value: 128 V stand-off ensures no interference during normal operation; 1500 W rating handles multi-kV transients without degradation. |
| Telecom Line Card Surge Protection | Consumer Power Adapter Input Stage |
Use Scenario: Guarding Ethernet PHY power pins (3.3 V/5 V) against ESD and secondary lightning surges in outdoor base stations. IC Role / Device Role / Timing Role: Secondary-level TVS after primary GDT/MOV, providing fast, low-clamp protection for sensitive silicon. Use Value: Sub-1 ns response and 207 V clamping prevent latch-up or gate oxide rupture in Ethernet transceivers. |
Use Scenario: Safeguarding AC-DC adapter primary-side rectifier output against mains overvoltage and capacitor discharge spikes. IC Role / Device Role / Timing Role: Parallel-mounted across bulk capacitor, diverting energy during brownout recovery or hot-plug events. Use Value: 175 °C max junction temperature allows operation near transformer heat sources; RoHS/E3 compliance meets global safety certifications. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150A | Lower peak power (600 W), smaller SMB package (vs. 1.5KE), 150 V VBR (143–158 V range overlaps) | Not AEC-Q101 qualified; limited to commercial-grade consumer/industrial use | Select when board space is constrained and 600 W surge margin suffices; verify thermal derating for same PCB layout |
| 1.5KE150A-E3/54 | Same electrical specs and 1.5KE package, but commercial-grade (no AEC-Q101), E3 suffix only (not HE3) | Lacks JESD 201 Class 2 whisker resistance and automotive qualification | Use where cost sensitivity outweighs automotive reliability requirements; not suitable for under-hood deployment |
Compared with 1N6299HE3/73, SMBJ150A offers footprint reduction at the expense of surge robustness and automotive qualification, while 1.5KE150A-E3/54 matches form/fit/function but omits AEC-Q101 and enhanced whisker resistance - making 1N6299HE3/73 the sole choice for production automotive designs requiring full qualification traceability.

FAQ
What is the breakdown voltage tolerance of the 1N6299HE3/73?
The 1N6299HE3/73 has a specified breakdown voltage range of 143 V minimum to 158 V maximum at 1 mA test current, corresponding to ±5% tolerance around the nominal 150 V rating. This tight distribution ensures consistent clamping behavior across production lots and supports reliable system-level surge margin calculations in automotive and industrial designs.
Is the 1N6299HE3/73 suitable for bidirectional transient protection?
No, the 1N6299HE3/73 is a unidirectional TVS diode, indicated by the "A" suffix and presence of cathode band marking. For bidirectional protection, Vishay offers the 1N6299CA variant (not 1N6299HE3/73), which lacks polarity marking and conducts symmetrically in both directions - essential for AC-coupled or differential signal line protection.
Does the 1N6299HE3/73 meet AEC-Q101 requirements?
Yes, the 1N6299HE3/73 is explicitly AEC-Q101 qualified per Vishay documentation (Document Number 88301, Revision 09-Aug-2022). The "HE3" suffix denotes RoHS compliance plus AEC-Q101 qualification, validated for temperature cycling, humidity testing, and mechanical shock - confirming suitability for automotive powertrain and chassis applications.
What is the maximum clamping voltage of the 1N6299HE3/73 under surge conditions?
The 1N6299HE3/73 clamps to a maximum of 207 V when subjected to its rated 7.2 A peak pulse current (10/1000 µs waveform). This value is measured per JEDEC standard and represents the upper limit of voltage imposed on protected circuitry during worst-case transient events - critical for ensuring downstream ICs remain within absolute maximum ratings.
How does the thermal resistance of the 1N6299HE3/73 affect PCB layout?
The 1N6299HE3/73 has RθJA = 75 °C/W, meaning each watt of dissipated power raises junction temperature by 75 °C above ambient. To maintain TJ ≤ 175 °C at 75 °C ambient, PCB copper pour must be optimized - typically ≥1 in² (6.5 cm²) of 2 oz copper connected to both leads - otherwise thermal derating reduces usable surge capability below datasheet ratings.
