Product details
Overview
MPTE-015G 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 15 V working peak reverse voltage (VRWM), clamps to ≤25 V at 60 A peak pulse current (IPP), and responds in <1 ns - deployed in power supplies, medical equipment, and industrial controls where fast, robust overvoltage protection is required.
For engineers reviewing the MPTE-015G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage at rated IPP, VRWM margin relative to operating voltage, thermal derating above 75°C, lead temperature limits during soldering, and axial-leaded Surmetic package compatibility with through-hole assembly processes.
Technical Context
The MPTE-015G operates as a Zener-based avalanche diode, leveraging controlled breakdown to clamp transients while maintaining low dynamic impedance (<1 Ω typical). Its unidirectional configuration provides reverse-biased protection only, requiring correct polarity placement across protected lines.
It delivers 1500 W nonrepetitive peak power per 1 ms pulse (per Figure 5), with steady-state dissipation derated to 5.0 W at TL ≤ 75°C and thermal resistance RJL = 20 °C/W. Clamping performance is specified at IPP = 60 A, VC ≤ 25 V, with VBR = 17.6–20.6 V at IT = 1.0 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 15 V - maximum continuous reverse operating voltage before clamping begins; must exceed circuit's peak DC/AC voltage. |
| VC @ IPP | ≤25 V @ 60 A - clamped voltage seen by protected IC during worst-case surge; defines maximum stress on downstream components. |
| IPP | 60 A - peak pulse current capability at 1 ms pulse width; determines survivability under IEC 61000-4-5 Level 4 surges. |
| VBR @ IT | 17.6–20.6 V @ 1.0 A - breakdown voltage range defining turn-on threshold; tight tolerance enables predictable protection onset. |
| Response Time | <1 ns - time from transient onset to clamping initiation; ensures protection before logic-level devices experience overstress. |
| ESD Rating | Class 3 (>16 kV HBM) - qualifies for high-reliability environments including medical and industrial end-equipment. |
| Leakage Current | <2.0 µA @ VRWM - minimal standby power loss and signal integrity impact in high-impedance circuits. |
Pinout & Package
MPTE-015G uses an axial-leaded Surmetic plastic package (Case 41A), with cathode identified by a polarity band. Leads are tin-plated, solderable at 230°C for 10 seconds at 1/16″ from case. Mounting position is unrestricted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Ground reference side | Connected to system ground or lower-potential rail; completes current path during reverse transient clamping. |
| Cathode | Protected line connection / High-side terminal | Connected to the line being protected (e.g., +12 V rail); polarity band marks this terminal for correct orientation. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W Peak Pulse Power | Enables single-device protection against severe surges (e.g., lightning-induced, inductive kickback) without external current sharing. |
| Low Clamping Ratio (VC/VBR ≈ 1.3) | Minimizes overvoltage overshoot during clamping - critical for safeguarding 15 V-tolerant analog front-ends and microcontrollers. |
| Pb-Free Axial Package (Case 41A) | Complies with RoHS and JEDEC J-STD-020 reflow/soldering standards; supports automated through-hole insertion and wave soldering. |
| −65°C to +175°C Operating Range | Validates use in extended-temperature industrial and automotive under-hood applications without derating penalties. |
| Dynamic Impedance <1 Ω | Ensures stable clamping under varying surge amplitudes - avoids voltage runaway during multi-pulse or decaying waveform events. |
Applications
| Industrial Power Supply Protection | Medical Equipment Input Stage |
|---|---|

Use Scenario: Protects AC/DC converter outputs and DC bus rails from load dump and EFT bursts in PLC power modules. IC Role / Device Role / Timing Role: Unidirectional TVS placed across +15 V output rail and ground, clamping transients before they reach voltage regulators and ADC references. Use Value: Limits rail excursion to ≤25 V during 60 A surges, preserving 15 V LDO functionality and preventing latch-up in downstream 16-bit SAR ADCs. |
Use Scenario: Shields patient-connected analog front-end inputs (e.g., ECG leads) from ESD discharge and defibrillator coupling. IC Role / Device Role / Timing Role: Mounted at connector entry point, shunting >16 kV HBM ESD energy away from precision op-amps and isolation amplifiers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A | Surface-mount SMB package (vs. axial MPTE-015G); 600 W peak power (vs. 1500 W); VC = 24.4 V @ 24.7 A. | Lower surge capacity suits board-level ESD-only protection; unsuitable for high-energy industrial surges. | Select SMBJ15A only when PCB space constraints prohibit axial components and surge threat level is limited to IEC 61000-4-2. |
| P6KE15A | Same axial package (Case 157), but 600 W rating; VC = 23.2 V @ 25.9 A; higher leakage (5 µA vs. 2 µA). | Limited to lower-duty-cycle applications; not qualified for continuous 175°C operation like MPTE-015G. | Choose P6KE15A only for cost-sensitive consumer designs where full 1500 W capability and extended temperature range are unnecessary. |
Compared with SMBJ15A and P6KE15A, MPTE-015G delivers 2.5× higher peak power, superior thermal robustness (175°C TJ max), and tighter leakage - making it the sole choice for mission-critical industrial and medical systems requiring sustained surge immunity.

FAQ
What is the maximum clamping voltage of MPTE-015G at its rated peak pulse current?
The MPTE-015G clamps to a maximum of 25 V at its rated peak pulse current of 60 A (1 ms pulse width). This value is measured per the standard surge waveform in Figure 5 of the datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. Maintaining VC ≤25 V ensures compatibility with 15 V-rated downstream components such as regulators and interface ICs.
Is MPTE-015G suitable for bidirectional signal line protection?
No, MPTE-015G is strictly unidirectional and must be used only in reverse-biased configurations - cathode to the protected line, anode to ground. For bidirectional protection (e.g., data lines with AC signals), ON Semiconductor offers the MPTE-15C variant or separate series like 1N6382–1N6389. Using MPTE-015G on AC-coupled lines risks forward conduction and failure.
What is the lead temperature limit for soldering MPTE-015G?
The maximum lead temperature for soldering MPTE-015G is 230°C, applied for no longer than 10 seconds at a distance of 1/16″ (1.6 mm) from the plastic case body. Exceeding this limit risks internal bond wire damage or delamination of the Surmetic encapsulant, compromising surge endurance and long-term reliability.
How does MPTE-015G compare to standard Zener diodes in transient suppression?
Unlike general-purpose Zener diodes, MPTE-015G is optimized for transient suppression: it features lower dynamic impedance (<1 Ω), guaranteed <1 ns response, 1500 W peak power handling, and rigorous ESD qualification (>16 kV HBM). Standard Zeners lack surge-rated construction and often exhibit inconsistent clamping or thermal runaway under pulse stress - MPTE-015G avoids both.
Can MPTE-015G be used in parallel to increase surge current handling?
No - MPTE-015G is not characterized or recommended for parallel operation. Variations in VBR and dynamic impedance between units cause current imbalance, leading to premature failure of one device. For higher current requirements, select a higher-rated part (e.g., MPTE-22G) or consult ON Semiconductor's application note AN-4002 for staged protection topologies.
