Product details
Overview
1N6380 from ON Semiconductor is a unidirectional 1500 W peak power TVS diode designed for transient voltage suppression in DC power rails and signal lines. It features a 36 V working peak reverse voltage (VRWM), clamps at 65.2 V @ 23 A IPP, exhibits <1 ns response time, and delivers Class 3 ESD protection (>16 kV HBM). It is used to safeguard power supplies, industrial controls, and medical equipment against lightning-induced surges and switching transients.
For engineers reviewing the 1N6380 datasheet, pinout, applications, or equivalent options, key selection criteria include its VRWM margin over system operating voltage, clamping voltage under rated surge current, low zener impedance, axial leaded Surmetic package thermal performance, and Pb-free compliance for modern assembly processes.
Technical Context
The 1N6380 operates as a unidirectional avalanche breakdown device with fixed zener-based clamping behavior. Its junction-to-lead thermal resistance is 20 °C/W, enabling reliable 5.0 W steady-state dissipation at TL ≤ 75°C with 3/8″ lead length - critical for sustained surge recovery in power supply front-ends.
It conforms to the standardized 1N6373–1N6381 series electrical architecture: breakdown voltage (VBR) is specified at IT = 1.0 A (min 42.4 V, max 54.3 V), leakage is ≤2.0 µA at VRWM, and dynamic impedance remains low across surge pulses up to 1 ms duration per Figure 5.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 36 V - Maximum continuous reverse operating voltage before clamping begins; must exceed system DC rail by ≥10% for margin. |
| IPP @ 1 ms | 23 A - Peak pulse current capability at 1500 W; defines minimum series impedance required to limit fault energy into protected ICs. |
| VC @ IPP | 65.2 V - Clamping voltage at 23 A; determines maximum transient voltage seen by downstream components during surge event. |
| VBR @ IT=1A | 42.4–54.3 V - Breakdown voltage range; ensures predictable turn-on threshold and tight tolerance for design validation. |
| Response Time | <1 ns - Enables suppression of fast-rising EFT/burst transients before sensitive logic or analog circuitry is stressed. |
| ESD Rating | >16 kV HBM - Meets IEC 61000-4-2 Level 4 for robust handling in automated assembly and field environments. |
| Package | Case 41A (Axial Leaded, Surmetic plastic) - Industry-standard through-hole package with 8.5–9.5 mm body length and 4.8–5.3 mm diameter for manual or wave soldering. |
Pinout & Package
Package: Axial-leaded Case 41A (Surmetic thermosetting plastic), cathode indicated by polarity band. Leads are solderable, corrosion-resistant, rated for 260°C @ 1/16″ from case for 10 s.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction; connected to ground or low-impedance return path in unidirectional TVS configuration. | Provides reference node for clamping action; must be routed with minimal inductance to avoid overshoot during fast transients. |
| Cathode | Protected line connection; tied to the voltage rail or signal line requiring transient suppression. | Carries full surge current during clamping; polarity band ensures correct orientation to prevent reverse-bias failure in DC applications. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W Peak Power Rating | Supports high-energy lightning surge immunity (IEC 61000-4-5 Level 3/4) without degradation when paired with appropriate series impedance. |
| Low Zener Impedance | Enables stable clamping voltage across varying surge currents - critical for protecting CMOS/MOS inputs with narrow voltage tolerances. |
| Pb-Free Surmetic Package | Complies with RoHS Directive 2011/65/EU and supports lead-free reflow/wave soldering without voiding thermal reliability. |
| Class 3 ESD Protection | Eliminates need for secondary ESD protection on board-level interfaces where human contact or handling risk exists. |
| Fast Response & Low Overshoot | Sub-nanosecond turn-on minimizes voltage excursion beyond VC; layout-critical but achievable with short leads and ground proximity. |
Applications
| Industrial Power Supply Input Protection | Medical Equipment ESD Shielding |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A | Surface-mount SMB package (vs. axial 1N6380); same 36 V VRWM, but lower 600 W peak power rating. | Requires PCB redesign for SMT placement; unsuitable for through-hole legacy systems or high-reliability wave-soldered assemblies. | Select when board space is constrained and surge energy is limited to ≤600 W; verify thermal pad layout matches SMBJ thermal derating curve. |
| 1N6381 | Same package and construction, but higher 45 V VRWM and 78.9 V clamping at 19 A IPP - not interchangeable without system voltage review. | Used where nominal rail is ≥40 V (e.g., 48 V telecom systems); incompatible with 36 V-rated circuits due to insufficient clamping margin. | Choose only if upgrading VRWM for higher-voltage systems; never substitute directly without recalculating worst-case clamping headroom. |
Compared with SMBJ36A and 1N6381, the 1N6380 uniquely balances 1500 W surge capacity, axial through-hole reliability, and 36 V system compatibility - making it optimal for industrial power entry designs where mechanical robustness and legacy assembly compatibility are mandatory.

FAQ
What is the maximum clamping voltage of the 1N6380 under rated surge conditions?
The 1N6380 clamps at 65.2 V when subjected to its rated peak pulse current of 23 A with a 1 ms waveform. This value is measured per Figure 5 in the official datasheet and represents the upper bound of voltage seen by protected circuitry during a full-power transient event. Designers must ensure this clamping level remains below the absolute maximum ratings of downstream components.
Can the 1N6380 be used in bidirectional transient protection circuits?
No - the 1N6380 is a unidirectional TVS diode, optimized for DC or single-polarity signal line protection. It conducts only in reverse breakdown and blocks forward current above ~3.5 V. For AC or bipolar signal lines, a dedicated bidirectional device such as P6KE36CA or SMBJ36CA must be selected instead.
What is the recommended minimum series impedance for the 1N6380 in a 23 A surge application?
To limit peak current to the 1N6380's rated 23 A during a 1500 W transient, the total series impedance (including PCB trace, fuse, and any discrete resistor) should be ≥(65.2 V − 36 V)/23 A ≈ 1.27 Ω. This ensures the device operates within its safe clamping window and avoids thermal runaway under repeated surges.
Does the 1N6380 require derating at elevated ambient temperatures?
Yes - the 1N6380's peak power rating must be derated above TA = 25°C per Figure 1, and its steady-state power dissipation drops linearly above TL = 75°C (20 mW/°C). At 100°C lead temperature, PD falls to 0 W; thus, thermal management via heatsinking or airflow is essential for sustained operation near rating limits.
Is the 1N6380 compatible with lead-free reflow soldering processes?
Yes - the "G" suffix confirms the 1N6380 uses a Pb-free Surmetic package qualified for standard lead-free reflow profiles (peak 260°C, 10 s at 1/16″ from case). Its thermosetting plastic body withstands multiple thermal cycles without delamination or parameter shift, meeting IPC-J-STD-020 moisture sensitivity level 1 requirements.
