Product details
Overview
1PMT5.0AT1 from onsemi is a unidirectional Zener transient voltage suppressor (TVS) in the POWERMITE® package, designed to protect 5.0 V DC circuits against ESD and surge transients. It delivers 200 W peak pulse power (10/1000 µs), clamps at 9.2 V @ 21.7 A, responds in <1 ns, and features 1.1 mm max height with integral heatsink tabs for thermal reliability.
For engineers reviewing the 1PMT5.0AT1 datasheet, pinout, applications, or equivalent options, key selection criteria include working peak reverse voltage (5.0 V), clamping voltage (9.2 V), surge current capability (21.7 A), JEDEC DO−216AA compliance, and Pb−free RoHS packaging for space-constrained portable electronics.
Technical Context
The 1PMT5.0AT1 operates as a unidirectional TVS diode, leveraging Zener avalanche breakdown to clamp transients above its 5.0 V working peak reverse voltage. Its low 3.2 °C/W junction-to-cathode thermal resistance and full metallic bottom enable efficient heat transfer to PCB copper, critical for sustained surge handling in compact layouts.
It meets Class 3 ESD immunity (>16 kV HBM), exhibits <1 ns response time, and maintains stable clamping across −55°C to +150°C operating range. The device is rated for 1000 W peak power under 8/20 µs waveform and derates linearly above 25°C ambient per published curves.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Peak Reverse Voltage (VRWM) | 5.0 V - Maximum continuous reverse voltage before clamping begins; matches 5 V logic/bus rails. |
| Breakdown Voltage (VBR) @ IT = 10 mA | 6.4–7.0 V - Ensures reliable turn-on margin above VRWM without premature conduction. |
| Clamping Voltage (VC) @ IPP = 21.7 A | 9.2 V - Limits downstream voltage during 10/1000 µs surge; protects 5 V ICs with ~85% headroom. |
| Peak Pulse Power (Ppk) | 200 W @ 10/1000 µs - Sustains high-energy transients common in I/O and power line interfaces. |
| ESD Rating (HBM) | >16 kV - Complies with IEC 61000-4-2 Level 4 for robust system-level ESD protection. |
| Package | POWERMITE® (DO−216AA) - 8.45 mm² footprint, 1.1 mm max height, JEDEC-registered surface-mount package. |
| Thermal Resistance (RJcathode) | 3.2 °C/W - Enables effective heat dissipation via cathode tab to PCB copper, supporting repeated surges. |
Pinout & Package
1PMT5.0AT1 uses the POWERMITE® (DO−216AA) surface-mount package: 2-pin, cathode-anode configuration, with cathode indicated by polarity band and short lead orientation toward sprocket holes in tape. Full metallic bottom enables direct thermal coupling to PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Transient Clamp Output / Heat Sink Node | Connected to protected circuit's ground or return path; serves as primary thermal interface to PCB copper pour. |
| 2 (Anode) | Protected Line Input | Connected to signal or power line requiring protection; reverse-biased during normal operation. |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile POWERMITE® package | 1.1 mm max height and 8.45 mm² footprint - fits ultra-thin mobile designs where SMA or SOD-123 are too tall or large. |
| Integral heatsink/locking tabs | Molded metal tabs on cathode side - enhance mechanical retention during reflow and improve thermal conduction to PCB. |
| Full metallic bottom | Eliminates flux entrapment and provides uniform solder wetting - improves assembly yield and long-term thermal interface reliability. |
| Fast response time | <1 ns turn-on - intercepts ESD events before sensitive CMOS inputs reach destructive voltage levels. |
| Pb−free & RoHS compliant | Meets global environmental regulations without compromising surge performance or thermal behavior. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Same VRWM (5.0 V) and clamping (9.2 V), but SMA package (2.5 mm height, 2× larger footprint) | Less suitable for ultra-thin devices; higher thermal resistance (RJA = 50°C/W vs. 248°C/W for 1PMT5.0AT1) | Choose SMAJ5.0A only when board height >1.5 mm is acceptable and thermal mass is abundant. |
| 1.5SMC5.0A | Higher peak power (1500 W), but SMC package (7.1 mm × 6.2 mm, 2.6 mm height); no integral heatsink tabs | Better for high-energy industrial surges, but incompatible with miniaturized consumer layouts | Select 1.5SMC5.0A when 8/20 µs surge energy exceeds 200 W and PCB real estate permits larger footprint. |
Compared with SMAJ5.0A and 1.5SMC5.0A, the 1PMT5.0AT1 uniquely balances ultra-low profile (1.1 mm), high thermal efficiency (3.2 °C/W cathode-to-tab), and verified 200 W surge capability-making it optimal for next-generation portable electronics where height and thermal management are co-constrained.

FAQ
What is the exact working peak reverse voltage (VRWM) of the 1PMT5.0AT1?
The 1PMT5.0AT1 has a specified working peak reverse voltage (VRWM) of 5.0 V. This value is guaranteed across temperature and represents the maximum DC or continuous peak operating voltage the device can withstand without entering breakdown. It is explicitly defined in the Electrical Characteristics table on page 3 of the official datasheet, and aligns with the "5.0" in the part number.
Does the 1PMT5.0AT1 meet industry-standard ESD requirements?
Yes, the 1PMT5.0AT1 is rated for Class 3 Human Body Model (HBM) ESD protection with >16 kV capability. This is confirmed in the Specification Features section and validated per ANSI/ESDA/JEDEC JS-001. The device is intended for system-level ESD hardening in consumer and portable electronics where IEC 61000-4-2 Level 4 compliance is required.
What is the clamping voltage of the 1PMT5.0AT1 at its rated peak pulse current?
The 1PMT5.0AT1 clamps to a maximum of 9.2 V at its peak pulse current of 21.7 A under the standard 10/1000 µs waveform. This value is measured and guaranteed in the Electrical Characteristics table (page 3), and defines the upper voltage limit imposed on protected circuitry during surge events.
Is the 1PMT5.0AT1 compatible with lead-free reflow soldering processes?
Yes, the 1PMT5.0AT1 is Pb−free and RoHS compliant, qualified for lead-free reflow soldering at 260°C for 10 seconds. Its plastic case is void-free and thermosetting, and all external surfaces are corrosion resistant with readily solderable leads-fully meeting J-STD-020 moisture sensitivity and JEDEC reflow specifications.
How does the POWERMITE® package of the 1PMT5.0AT1 compare thermally to the SMA package?
The 1PMT5.0AT1's POWERMITE® package delivers equivalent thermal performance to the SMA while occupying 50% less footprint area and achieving a maximum height of just 1.1 mm. Its junction-to-cathode thermal resistance is 3.2 °C/W, and the full metallic bottom enables superior heat transfer to PCB copper versus SMA's plastic-body thermal path.
