Product details
Overview
MPTE-5RL4G from ON Semiconductor is a unidirectional 1500 W peak power Mosorb Zener transient voltage suppressor (TVS) designed for parallel protection of sensitive electronics against ESD and surge events. It features a 5.0 V working peak reverse voltage (VRWM), clamps to 9.4 V at 160 A peak pulse current (IPP), and delivers sub-1 ns response time with <5 µA leakage above 10 V - deployed in power supply input stages, industrial control I/O ports, and medical equipment front-end protection.
For engineers reviewing the MPTE-5RL4G datasheet, pinout, applications, or equivalent options, this page provides verified electrical parameters, axial lead package details, real-world clamping behavior, and validated alternative parts for surge protection design validation and BOM optimization.
Technical Context
This device operates as a unidirectional Zener-based TVS diode, leveraging avalanche breakdown to clamp transients while maintaining low dynamic impedance (<1 Ω typical). Its 1500 W peak power rating applies to a non-repetitive 1 ms pulse per Figure 5, with thermal derating above 25°C ambient and 75°C lead temperature.
The MPTE-5RL4G uses a Surmetic axial-leaded plastic package (Case 41A) with cathode band polarity marking, Pb-free construction, and solderability rated at 230°C for 10 seconds at 1/16″ from case. It exhibits ESD robustness >16 kV HBM and clamps within 9.4 V at 160 A IPP - critical for protecting CMOS/MOS inputs without overvoltage stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5.0 V - Maximum continuous reverse operating voltage; must be ≥ circuit's DC/peak operating voltage to avoid leakage-induced power loss. |
| VC @ IPP | 9.4 V @ 160 A - Clamped voltage during worst-case surge; ensures downstream ICs (e.g., 5 V logic) remain below absolute maximum ratings. |
| IPP | 160 A - Peak pulse current capability per 1 ms waveform; defines surge immunity level for IEC 61000-4-5 Level 4 (4 kV/2 Ω) compliance margin. |
| Response Time | <1 ns - Enables suppression before transient energy couples into protected circuitry; eliminates need for additional RC filtering in fast-edge systems. |
| Leakage Current | <5 µA @ VRWM - Negligible standby power draw; suitable for battery-backed or low-quiescent systems where leakage impacts runtime. |
| ESD Rating | Class 3 (>16 kV HBM) - Meets stringent electrostatic discharge immunity requirements for medical and industrial touch interfaces. |
| Package | Case 41A axial lead - Standard through-hole mounting; 8.5–9.5 mm body length, 4.8–5.3 mm diameter, RoHS-compliant Pb-free finish. |
Pinout & Package
MPTE-5RL4G is housed in an axial-leaded Surmetic plastic package (Case 41A), with cathode identified by a colored band. Leads are tin-plated copper, solderable at 230°C for 10 seconds at 1/16″ from case. Mounting position is unrestricted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to system ground or return path; carries full surge current during clamping event. |
| Cathode | High-side connection point | Connected to protected line (e.g., +5 V rail); polarity band marks this terminal for correct orientation during PCB assembly. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power | Supports high-energy surge handling (e.g., lightning-induced surges on AC/DC inputs) without degradation across 1000+ events. |
| Clamp voltage ≤9.4 V @ 160 A | Guarantees safe operation of 5 V TTL/CMOS devices under worst-case transient conditions per IEC 61000-4-5. |
| Sub-1 ns response time | Minimizes voltage overshoot before clamping engages - critical for protecting high-speed data lines and microcontroller I/O pins. |
| Pb-free Surmetic axial package | Enables compliant through-hole manufacturing with standard wave-solder profiles and long-term reliability in humid industrial environments. |
| ESD rating >16 kV HBM | Eliminates need for secondary ESD protection on user-accessible ports in medical and test equipment designs. |
Applications
| Industrial Power Supply Input Protection | Medical Equipment Front-End Surge Suppression |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6373G | Same electrical specs (VRWM = 5.0 V, VC = 9.4 V @ 160 A), identical Case 41A package, JEDEC-standard marking. | No functional difference; used interchangeably in legacy designs where JEDEC part numbering is mandated by procurement policy. | Select 1N6373G when cross-referencing to JEDEC-compliant BOMs or when sourcing from distributors stocking legacy part numbers. |
| ICTE-5G | Identical VRWM, VC, IPP, and package; differs only in ON Semiconductor internal device code and marking layout (ICTE vs MPTE). | No impact on circuit performance or layout; same thermal and mechanical behavior in board assembly and field operation. | Choose ICTE-5G if aligned with ON Semiconductor's ICTE-series documentation or when consolidating across multiple ON-supplied TVS families. |
Compared with MPTE-5RL4G, both 1N6373G and ICTE-5G deliver identical clamping performance and surge handling but differ only in part-numbering convention and marking - enabling drop-in substitution without layout, thermal, or reliability impact.

FAQ
What is the clamping voltage of MPTE-5RL4G at its rated peak pulse current?
The MPTE-5RL4G clamps to a maximum of 9.4 V at its rated peak pulse current of 160 A, measured using the standardized 1 ms exponential waveform defined in Figure 5 of the datasheet. This value ensures compatibility with 5 V logic systems and is guaranteed across temperature and production lots - critical for validating surge immunity in safety-critical designs.
Is MPTE-5RL4G compatible with lead-free soldering processes?
Yes, MPTE-5RL4G is supplied in a Pb-free Surmetic axial package and qualified for lead-free wave and reflow soldering. The leads withstand 230°C for 10 seconds at 1/16″ from the case, meeting IPC-J-STD-020 moisture sensitivity and JEDEC J-STD-002B solderability requirements - making it suitable for modern RoHS-compliant manufacturing lines.
How does MPTE-5RL4G differ from bidirectional TVS diodes like MPTE-5RL4C?
The MPTE-5RL4G is unidirectional and optimized for DC rail protection where polarity is fixed (e.g., +5 V to ground), offering lower leakage and tighter clamping than bidirectional variants. In contrast, MPTE-5RL4C handles AC or floating signals but exhibits higher capacitance and symmetric clamping - MPTE-5RL4G should be selected when protecting polarized supplies with minimal standby current budget.
Can MPTE-5RL4G be used in place of SMAJ5.0A or SMCJ5.0A surface-mount TVS diodes?
No - MPTE-5RL4G is an axial-leaded through-hole device (Case 41A), while SMAJ5.0A and SMCJ5.0A are surface-mount packages (DO-214AC and DO-214AB). Though electrically similar in VRWM and VC, their thermal paths, PCB layout, and assembly processes differ fundamentally; direct substitution requires mechanical redesign and thermal validation.
What is the maximum steady-state power dissipation rating for MPTE-5RL4G?
The MPTE-5RL4G has a steady-state power dissipation rating of 5.0 W at lead temperature (TL) ≤75°C, with derating at 20 mW/°C above that threshold. This rating applies only to continuous DC or low-frequency conditions - not surge events - and assumes 3/8″ lead length; exceeding it risks thermal runaway and permanent parametric shift.
