Product details
Overview
1PMT5936BT1G from onsemi is a 3.2 W surface-mount Zener diode in the POWERMITE® (DO−216AA) package, with nominal Zener voltage 30 V, test current 12.5 mA, dynamic impedance 750 Ω at IZT, and maximum reverse leakage 0.25 μA at VR = 22.8 V. It delivers stable voltage regulation in space-constrained portable electronics and industrial power rails.
For engineers reviewing the 1PMT5936BT1G datasheet, pinout, applications, or equivalent options, key selection criteria include its 30 V nominal Zener voltage, 3.2 W power dissipation at cathode temperature of 75°C, 1.1 mm max height, JEDEC-registered DO−216AA footprint, and Pb-free compliance.
Technical Context
This device operates as a precision voltage reference and overvoltage clamp in low-power DC rails. Its thermal design centers on the cathode tab (Terminal 1), which serves as both electrical connection and primary heat path-RJcathode = 23°C/W enables 3.2 W dissipation when Ttab = 75°C.
The 1PMT5936BT1G exhibits a positive temperature coefficient above ~5 V, typical for 30 V Zeners, and maintains low capacitance (<100 pF at 50% VR) for minimal signal coupling in filtering applications. Its ESD rating exceeds 16 kV (HBM Class 3) supports robustness in handheld device interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 28.5–31.5 V @ IZT = 12.5 mA - defines regulated output range under standard test conditions |
| Power Dissipation | 3.2 W @ Ttab = 75°C - usable full power only when cathode tab is thermally managed |
| Zener Impedance | 750 Ω max @ IZT - limits regulation accuracy under varying load currents |
| Reverse Leakage | 0.25 μA max @ VR = 22.8 V - ensures minimal standby current in high-impedance bias networks |
| Package | POWERMITE® (DO−216AA), 1.1 mm max height - enables ultra-thin PCB designs with 8.45 mm² footprint |
| ESD Rating | Class 3 (>16 kV HBM) - withstands handling and interface transients without degradation |
| Thermal Resistance | RJcathode = 23°C/W - requires thermal pad or copper pour under cathode tab for full power operation |
Pinout & Package
Package: POWERMITE® (JEDEC DO−216AA), plastic surface-mount case with integral heat sink tabs and full metallic bottom. Dimensions: 1.75–2.05 mm (L) × 1.75–2.18 mm (W) × max 1.1 mm (H). Cathode indicated by polarity band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Regulated output node / Heat sink terminal | Connected to regulated rail; must be soldered to thermal pad for rated 3.2 W dissipation |
| 2 (Anode) | Reference/ground return | Low-impedance return path; not used for thermal conduction in this package |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile thermal package | 1.1 mm max height with RJcathode = 23°C/W - enables thin-profile battery-powered devices without sacrificing power rating |
| Full metallic bottom | Eliminates flux entrapment during reflow - improves solder joint reliability and reduces post-process cleaning needs |
| Pb-free construction | RoHS-compliant "G" suffix version - meets global environmental regulations without derating or performance trade-offs |
| Small footprint area | 8.45 mm² - saves >50% board area vs. SMA while maintaining equivalent thermal performance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5936BRLG | Same 30 V nominal Zener, but in axial DO-41 package (5.2 mm height, 2.7 mm diameter); 1.2 W rating at 50°C ambient | Requires through-hole mounting and larger board area; unsuitable for ultra-thin or high-density SMT layouts | Select when legacy through-hole assembly or higher ambient temperature derating is required |
| MMSZ5256ET1G | 30 V Zener in SOD-123 package; 500 mW rating; 17 Ω ZZT; 100 nA leakage @ 24 V | Lower power, lower impedance, lower leakage - suited for low-current references, not 3.2 W clamping | Select when precision low-current biasing is needed, not high-power regulation or transient clamping |
Compared with 1N5936BRLG and MMSZ5256ET1G, the 1PMT5936BT1G uniquely combines 3.2 W dissipation in a 1.1 mm profile, making it the only option for space-constrained, high-energy clamping where thermal management is localized to the cathode tab.

FAQ
What is the nominal Zener voltage of the 1PMT5936BT1G and how is it tested?
The 1PMT5936BT1G has a nominal Zener voltage of 30 V, with a guaranteed range of 28.5 V to 31.5 V measured at a test current (IZT) of 12.5 mA and junction temperature of 25°C. This value is verified per the electrical characteristics table on page 2 of the official onsemi datasheet, and applies strictly under those defined thermal and current conditions.
Can the 1PMT5936BT1G dissipate its full 3.2 W rating on a standard FR-4 PCB?
No-the 3.2 W rating for the 1PMT5936BT1G applies only when the cathode tab (Terminal 1) is maintained at 75°C. On a standard FR-4 board without thermal enhancement, derating is required. Full power demands a dedicated thermal pad and copper pour connected to Terminal 1, leveraging its RJcathode = 23°C/W specification.
Is the 1PMT5936BT1G compatible with lead-free reflow processes?
Yes-the "G" suffix confirms the 1PMT5936BT1G is Pb-free and qualified for standard lead-free reflow profiles, including peak temperatures up to 260°C for 10 seconds. Its void-free transfer-molded plastic case and corrosion-resistant finish ensure reliable solderability without flux entrapment.
How does the 1PMT5936BT1G compare to SMA-packaged Zeners in thermal performance?
The 1PMT5936BT1G delivers equivalent thermal resistance to SMA packages (RJA = 248°C/W) while occupying 50% less footprint and standing only 1.1 mm tall. Its integral heat sink tabs and full metallic bottom enable direct thermal conduction from the cathode, unlike SMA's reliance on lead-frame conduction alone.
What is the maximum reverse leakage current specified for the 1PMT5936BT1G?
The 1PMT5936BT1G specifies a maximum reverse leakage current of 0.25 μA at VR = 22.8 V and TL = 25°C. This low leakage ensures minimal error in high-impedance reference networks and preserves battery life in always-on portable applications.
