Product details
Overview
1N6375 from ON Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in axial-leaded Surmetic plastic package, designed for parallel clamping of high-energy transients. It features 10 V working peak reverse voltage (VRWM), 16.7 A peak pulse current (IPP), 13.7 V clamping voltage (VC) at IPP, 11.7 V breakdown voltage (VBR) at 1 mA, and sub-1 ns response time - used to protect power supplies, industrial controls, and medical equipment from ESD and surge events.
For engineers reviewing the 1N6375 datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM matching system DC bus voltage, VC margin relative to IC absolute maximum ratings, thermal derating above 75°C lead temperature, and axial mounting compatibility with legacy through-hole PCB layouts.
Technical Context
The 1N6375 operates as a silicon avalanche diode with unidirectional polarity (cathode-banded), activated only during reverse overvoltage events. Its clamping action begins at VBR = 11.7 V (min) and limits transient voltage to VC = 13.7 V at IPP = 16.7 A under 1 ms 8.3 ms half-sine pulse conditions.
Thermal design requires attention to junction-to-lead resistance (RJL = 20 °C/W) and steady-state power dissipation (PD = 5.0 W @ TL ≤ 75°C), with linear derating above that temperature. It delivers Class 3 ESD immunity (>16 kV HBM) and exhibits low leakage (<2.0 μA @ VRWM = 10 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 10 V - Maximum continuous reverse operating voltage before clamping initiates; must exceed circuit's normal DC/peak AC voltage. |
| VBR @ IT=1 mA | 11.7 V (min) - Avalanche breakdown threshold; defines onset of protective conduction. |
| VC @ IPP=16.7 A | 13.7 V - Clamped voltage during 1 ms transient; determines maximum stress on downstream components. |
| PPK | 1500 W - Peak pulse power handling capability per non-repetitive 1 ms surge. |
| Response Time | <1 ns - Enables suppression of fast-rising transients before sensitive ICs experience overstress. |
| IR @ VRWM | <2.0 μA - Low leakage ensures minimal standby power loss and signal integrity in high-impedance nodes. |
| ESD Rating | Class 3 (>16 kV HBM) - Validated robustness against human-body model electrostatic discharge events. |
Pinout & Package
Package: Axial-leaded Surmetic plastic case (ON Semiconductor Case 41A), Pb-free, cathode indicated by band. Dimensions: A = 8.5–9.5 mm length, B = 4.8–5.3 mm diameter, D = 0.96–1.06 mm lead diameter, K = 25.4 mm lead length.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Ground reference in unidirectional clamp | Connected to circuit ground or low-side return path; carries surge current to ground during clamping. |
| Cathode | Reverse-biased clamping terminal / Input protection node | Connected to protected line (e.g., +12 V rail); avalanche conduction begins here when VRWM exceeded. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power | Supports IEC 61000-4-5 Level 4 (4 kV/2 Ω) surge testing without failure when properly mounted. |
| Clamping ratio VC/VBR = 1.17 | Indicates tight voltage control - low overshoot ensures reliable protection of 12 V logic and analog interfaces. |
| Sub-1 ns response time | Enables effective suppression of EFT/burst transients (IEC 61000-4-4) with rise times down to 5 ns. |
| Pb-free Surmetic axial package | RoHS-compliant, corrosion-resistant finish with 260°C solderability for automated through-hole assembly. |
| Low zener impedance | Minimizes dynamic voltage rise during high di/dt surges, critical for protecting fast-switching MOSFET gates. |
Applications
| Industrial Power Supply Protection | Medical Equipment Surge Suppression |
|---|---|
Use Scenario: Installed across DC input rails of switch-mode power supplies to absorb lightning-induced surges and load-dump transients. IC Role / Device Role / Timing Role: Unidirectional TVS diode providing millisecond-scale clamping during 1500 W transient events. Use Value: Limits rail voltage to 13.7 V during 16.7 A surges, preventing overvoltage damage to upstream rectifiers and downstream PWM controllers. | Use Scenario: Placed on patient-connected signal lines (e.g., ECG front-end inputs) to meet IEC 60601-1-2 ESD immunity requirements. IC Role / Device Role / Timing Role: Fast-response transient suppressor absorbing >16 kV HBM discharges before reaching precision amplifiers. Use Value: Sub-1 ns activation and 2.0 μA leakage preserve signal integrity and common-mode rejection in microvolt-level biopotential circuits. |
| Programmable Logic Controller I/O Protection | Automated Test Equipment Power Rails |
Use Scenario: Mounted at DIN-rail-mounted PLC digital input terminals exposed to inductive kickback from solenoid loads. IC Role / Device Role / Timing Role: Axial-leaded TVS absorbing 8.3 ms half-sine surges up to 200 A forward surge current capability. Use Value: Withstands repeated 100 A transients while maintaining VRWM = 10 V compatibility with 24 V control logic levels. | Use Scenario: Used on ±15 V analog supply rails of ATE source-measure units to prevent latch-up during relay switching transients. IC Role / Device Role / Timing Role: Bidirectionally unused unidirectional device applied on positive rail with cathode to +15 V, anode to ground. Use Value: 13.7 V clamping prevents CMOS op-amp inputs from exceeding absolute maximum rating during 1 ms relay bounce events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | Surface-mount DO-214AA package; same VRWM (10 V) but lower PPK (600 W); VC = 17.0 V @ 34.4 A | Requires PCB redesign for SMT layout; higher VC reduces margin for 12 V systems | Select when board space is constrained and surge energy is ≤600 W |
| 1N6374 | Lower VRWM (8 V); VBR = 9.4 V (min); VC = 11.3 V @ 15 A; identical package and thermal specs | Better suited for 5 V–8 V logic rails; tighter clamping but reduced voltage headroom | Select when protecting 8 V nominal systems where 13.7 V clamping is excessive |
Compared with SMBJ10A and 1N6374, the 1N6375 offers optimal balance of 1500 W surge capacity, 10 V system compatibility, and axial through-hole mountability - making it preferred for industrial power entry and legacy control panel designs requiring field-serviceable replacement.

FAQ
What is the maximum clamping voltage of the 1N6375 during a standard 1 ms transient event?
The 1N6375 clamps to a maximum of 13.7 V at its rated peak pulse current of 16.7 A under the standardized 1 ms exponential waveform defined in the datasheet. This value is measured with specified test conditions including 25°C ambient temperature and proper lead length; actual clamping may vary slightly with PCB layout parasitics and thermal conditions during sustained operation.
Can the 1N6375 be used in bidirectional protection configurations?
No, the 1N6375 is a unidirectional TVS diode with cathode band marking and is not rated for reverse conduction. For bidirectional protection, two 1N6375 devices must be connected in series opposition, or a dedicated bidirectional part such as 1N6375R (if available) or SMAJ10CA should be selected instead.
What is the recommended minimum clearance distance when mounting the 1N6375 near heat sources?
Due to its thermal resistance of 20 °C/W (junction-to-lead), the 1N6375 must be mounted with ≥10 mm clearance from adjacent heat-generating components and routed with short, wide traces to minimize thermal coupling. Lead temperature must remain ≤75°C for full 5.0 W steady-state power rating; derating applies beyond that threshold per Figure 4 in the official datasheet.
Does the 1N6375 meet RoHS and REACH compliance requirements?
Yes, the "G" suffix in 1N6375, G explicitly denotes a Pb-free Surmetic package compliant with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The device uses lead-free terminations and halogen-free molding compound, with full material declarations available via onsemi's compliance portal.
How does the 1N6375 compare to metal-oxide varistors (MOVs) for surge protection?
The 1N6375 offers faster response (<1 ns vs. ~20–50 ns for MOVs), more precise voltage clamping (13.7 V vs. ±10% tolerance), and no degradation after repeated surges - unlike MOVs which wear out. However, MOVs handle higher total energy; the 1N6375 is best paired with upstream current-limiting impedance for multi-kA events.
