Product details
Overview
MPTE-005 from ON Semiconductor is a unidirectional Mosorb Zener transient voltage suppressor in axial leaded Surmetic plastic package, designed for parallel clamping protection of sensitive electronics. It features 5.0 V working peak reverse voltage (VRWM), 1500 W peak pulse power at 1 ms, clamping voltage of 9.4 V at 160 A peak pulse current (IPP), and sub-1 ns response time - deployed in power supply input stages and industrial control I/O interfaces.
For engineers reviewing the MPTE-005 datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM matching system DC bus voltage, VC vs. IPP performance under surge stress, thermal derating above 75°C, and axial lead solderability per 230°C/10s specification.
Technical Context
The MPTE-005 operates as a Zener-based avalanche diode with unidirectional polarity, activated when reverse voltage exceeds its 6.0 V minimum breakdown voltage (VBR) at 1 mA test current. Its low dynamic impedance and fast turn-on ensure effective suppression of ESD (Class 3 >16 kV HBM) and lightning-induced surges.
Thermal design relies on junction-to-lead resistance of 20 °C/W and steady-state power dissipation of 5.0 W at TL ≤ 75°C, with linear derating above that temperature. The device uses case 41A axial package with cathode band marking and Pb-free plating compatible with standard reflow and hand-soldering processes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5.0 V - maximum continuous reverse operating voltage before clamping begins; must exceed circuit's nominal DC rail. |
| IPP | 160 A - peak pulse current at which clamping occurs; defines surge handling capacity per 1 ms waveform. |
| VC @ IPP | 9.4 V - clamped voltage seen by protected circuit during 160 A transient; determines maximum stress on downstream ICs. |
| VBR @ IT=1 mA | 6.0–7.5 V - breakdown threshold range; ensures reliable turn-on without premature conduction. |
| IR @ VRWM | 300 µA - reverse leakage at 5.0 V; low enough to avoid power loss or false triggering in high-impedance nodes. |
| Response Time | < 1 ns - enables suppression of fast-rising transients before vulnerable components experience overvoltage. |
| Package | Case 41A axial lead - 8.5–9.5 mm body length, 4.8–5.3 mm diameter, cathode band polarity marking. |
Pinout & Package
MPTE-005 is a two-terminal axial-leaded device housed in ON Semiconductor's void-free, thermosetting plastic Surmetic Case 41A package. Cathode is marked by a visible band; anode is unmarked end. Leads are tin-plated, solderable, and rated for 230°C for 10 seconds at 1/16″ from case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / low-side connection | Connected to ground or low-voltage reference in unidirectional clamp configuration; carries forward surge current up to 200 A. |
| Cathode | Reverse clamping terminal / high-side connection | Connected to protected line (e.g., +5 V rail); initiates avalanche conduction when reverse voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power | Enables robust protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) on 5 V systems without cascading failure. |
| ESD rating >16 kV HBM | Meets Class 3 human-body-model immunity, eliminating need for supplemental ESD diodes in front-end interfaces. |
| Clamping ratio VC/VBR = 1.57 | Indicates tight voltage control - only 57% overhead above breakdown, minimizing stress on 5.5 V-tolerant logic. |
| Low zener impedance | Ensures stable clamping under varying current, critical for maintaining safe voltage during multi-pulse surge events. |
| Pb-free Surmetic package | Complies with RoHS and JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for automated assembly. |
Applications
| Industrial Power Supply Input Protection | Medical Equipment I/O Port Clamping |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6373, G | Same electrical specs and case 41A package; JEDEC-standardized marking instead of ON-specific MPTE prefix. | No functional difference; identical VRWM, VBR, VC, and IPP ratings per datasheet Table 3. | Select when JEDEC-compliant part numbering is required for BOM standardization or legacy procurement systems. |
| ICTE-5, G | Identical VRWM (5.0 V), VBR (6.0–7.5 V), VC (9.4 V @ 160 A), and package; differs only in ON internal device code labeling. | Same thermal and surge performance; used interchangeably in ON's own reference designs and evaluation boards. | Choose when sourcing from distributors stocking ICTE-series inventory or aligning with ON's alternate part numbering scheme. |
Compared with MPTE-005, both 1N6373, G and ICTE-5, G deliver identical clamping behavior, thermal limits, and surge endurance - differing solely in marking convention and orderable part number; all three share the same die, package, and qualification data.

FAQ
What is the maximum clamping voltage of MPTE-005 under surge conditions?
The MPTE-005 clamps to 9.4 V when subjected to its rated peak pulse current of 160 A (1 ms waveform). This value is measured per Figure 5 in the official datasheet and represents the maximum voltage imposed on the protected circuit during worst-case transient events. Designers must verify that downstream components tolerate this clamped voltage with margin.
Is MPTE-005 suitable for bidirectional signal line protection?
No, MPTE-005 is strictly unidirectional and must not be used on AC-coupled or bidirectional lines such as USB D+/D− or RS-485. Its cathode-anode polarity is fixed, and reverse conduction beyond VRWM triggers clamping only in one direction. For bidirectional protection, ON Semiconductor offers MPTE-8C through MPTE-45C variants explicitly rated for symmetrical surge handling.
What is the thermal resistance and power derating behavior of MPTE-005?
MPTE-005 has a junction-to-lead thermal resistance (RJL) of 20 °C/W and dissipates 5.0 W continuously at lead temperature ≤75°C, derating linearly above that point. At 100°C lead temperature, usable steady-state power drops to 0 W - confirming its suitability only for transient, not continuous, power dissipation. Layout must ensure adequate copper area and short leads for heat transfer.
Does MPTE-005 meet RoHS and lead-free assembly requirements?
Yes, MPTE-005 is supplied in a Pb-free Surmetic package compliant with RoHS Directive 2011/65/EU. Its leads are tin-plated and qualified for soldering at 230°C for 10 seconds at 1/16″ from the case, meeting IPC-J-STD-020 moisture sensitivity level (MSL) requirements for standard reflow profiles without pre-baking.
How does MPTE-005 compare to polymer-based TVS devices in surge response?
MPTE-005 uses Zener avalanche physics, delivering sub-1 ns response time and precise clamping voltage - significantly faster and more predictable than polymer PPTC or varistor-based protectors, which exhibit microsecond-scale activation and higher clamping variance. This makes MPTE-005 preferred for protecting fast digital interfaces and precision analog circuits where overshoot must be minimized.
