Product details
Overview
1N6300AHE3_B/C from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection of DC power rails and signal lines. It features a 152 V to 168 V breakdown voltage (VBR), 136 V maximum standoff voltage (VWM), 219 V clamping voltage at 6.8 A peak pulse current, 1500 W peak pulse power rating (10/1000 µs), and operates across –55 °C to +175 °C junction temperature range. It is used in automotive power supply inputs and industrial sensor interface protection.
For engineers reviewing the 1N6300AHE3_B/C datasheet, 1N6300AHE3_B/C pinout, 1N6300AHE3_B/C application, or 1N6300AHE3_B/C equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJL = 15.4 °C/W), JEDEC 1.5KE package dimensions, and real-world clamping behavior under transient surge conditions.
Technical Context
This unidirectional TVS diode employs a glass-passivated silicon junction optimized for fast response (<1 ns) and low incremental clamping resistance. Its 1500 W peak pulse power handling is defined per 10/1000 µs waveform with 0.01% duty cycle, and it maintains stable clamping performance up to 175 °C junction temperature.
The device exhibits 3.5 V forward voltage at 100 A (per spec note for ≤1.5KE220A series), 10 µA max reverse leakage at VWM, and a temperature coefficient of VBR of +0.108 %/°C - confirming positive drift with rising temperature, critical for thermal design margining in high-ambient environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 152 V / 168 V - ensures reliable conduction onset above normal operating voltage while avoiding false triggering during transients near VWM |
| VWM | 136 V - maximum continuous DC or RMS voltage the device blocks without significant leakage; sets upper limit for protected circuit operating voltage |
| VC @ IPPM | 219 V - clamped voltage seen by downstream circuitry during full 6.8 A 10/1000 µs surge; defines worst-case stress on protected ICs |
| PPPM | 1500 W - peak transient energy absorption capacity; determines survivability against lightning-induced surges (IEC 61000-4-5 Level 4) |
| IPPM | 6.8 A - peak current delivered into clamping region under standardized 10/1000 µs pulse; used to size series impedance for current limiting |
| TJ max. | +175 °C - enables operation in under-hood automotive and high-temperature industrial enclosures without derating penalties |
| RθJL | 15.4 °C/W - low junction-to-lead thermal resistance supports high-reliability solder-joint thermal cycling and sustained surge repetition |
Pinout & Package
Package: JEDEC 1.5KE molded epoxy case (Case Style 1.5KE), axial-leaded, RoHS-compliant matte tin-plated leads. Dimensions: 5.3 mm diameter × 9.5 mm length (0.210" × 0.375"), lead diameter 1.07 mm (0.042"). Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to ground or low-side return path when protecting positive rail; must be routed with low-inductance path to handle surge return current |
| Cathode | Current exit point during reverse-biased clamping | Connected to protected line (e.g., 12 V supply); color band identifies this terminal; determines polarity-sensitive placement in PCB layout |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A-E3/52 | DO-214AA (SMB) package; lower PPPM = 600 W; VBR = 178–197 V; higher VC = 259 V @ 2.3 A | Surface-mount alternative for space-constrained boards; unsuitable for high-energy surges requiring 1500 W dissipation | Select when PCB real estate limits axial-leaded devices and surge threat level is ≤IEC 61000-4-5 Level 2. |
| 1.5KE160AHE3_A | Same 1.5KE package and electrical specs, but HE3_A revision lacks AEC-Q101 qualification; identical VBR, VC, PPPM | Commercial-grade version for non-automotive use; no automotive stress validation or traceability documentation | Choose for cost-sensitive industrial or consumer applications where AEC-Q101 is not mandated. |
Compared with SMBJ160A-E3/52, the 1N6300AHE3_B/C delivers 2.5× higher surge energy handling and lower clamping ratio (VC/VBR = 1.30 vs. 1.46), while 1.5KE160AHE3_A offers identical protection performance without automotive qualification - making 1N6300AHE3_B/C the sole option when both high-energy clamping and AEC-Q101 compliance are required.

FAQ
What is the breakdown voltage range for the 1N6300AHE3_B/C?
The 1N6300AHE3_B/C has a guaranteed breakdown voltage (VBR) range of 152 V to 168 V at 1.0 mA test current, measured per JEDEC standard. This tight ±5% tolerance ensures consistent clamping onset across production lots and supports precise overvoltage margining in safety-critical designs such as automotive power supplies.
Is the 1N6300AHE3_B/C AEC-Q101 qualified?
Yes, the 1N6300AHE3_B/C is explicitly AEC-Q101 qualified per Vishay document 88301, footnote (2). This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing - confirming suitability for automotive under-hood and chassis applications.
What is the clamping voltage of the 1N6300AHE3_B/C at its rated peak pulse current?
The 1N6300AHE3_B/C clamps to a maximum of 219 V at its rated peak pulse current (IPPM) of 6.8 A, tested with a 10/1000 µs waveform. This value defines the maximum voltage imposed on protected circuitry during worst-case surge events and is critical for verifying compatibility with downstream IC absolute maximum ratings.
Does the 1N6300AHE3_B/C have a bidirectional variant?
No - the 1N6300AHE3_B/C is strictly unidirectional. Bidirectional variants in the same voltage grade use the "CA" suffix (e.g., 1.5KE160CA), and Vishay's datasheet confirms bidirectional types are only offered up to 1.5KE220CA. The "A" suffix in 1N6300AHE3_B/C denotes unidirectional polarity with cathode marking.
What is the thermal resistance from junction to lead (RθJL) for the 1N6300AHE3_B/C?
The 1N6300AHE3_B/C has a typical junction-to-lead thermal resistance (RθJL) of 15.4 °C/W, as specified in Vishay's thermal characteristics table. This low value enables efficient heat transfer from the silicon die to the PCB copper pour or heatsink via the leads, supporting reliable operation under repetitive surge conditions.
