Product details
Overview
1PMT5920BT3G from onsemi is a 6.2 V, 3.2 W surface-mount Zener diode in the POWERMITE® (DO-216AA) package, designed for precision voltage regulation and transient suppression in space-constrained portable electronics. It delivers 60.5 mA test current, <5 µA leakage at 4.0 V reverse bias, 200 Ω dynamic impedance at IZT, and operates from −55 °C to +150 °C.
For engineers reviewing the 1PMT5920BT3G datasheet, pinout, applications, or equivalent options, key selection criteria include its 1.1 mm max height, 8.45 mm² footprint, Pb-free construction, cathode-indicated polarity band, and thermal performance matching SMA with 50% smaller area.
Technical Context
The 1PMT5920BT3G functions as a two-terminal voltage reference device operating in reverse breakdown mode, with nominal Zener voltage of 6.2 V ±4.8% (5.89–6.51 V) at 60.5 mA. Its thermal design relies on direct cathode tab conduction (RJcathode = 23 °C/W), enabling 3.2 W dissipation when the cathode tab is held at 75 °C.
It exhibits low-profile mechanical integration via the DO-216AA outline (Case 457), featuring full metallic bottom for flux-free soldering, integral heat sink tabs, and JEDEC-compliant tape-and-reel packaging (12,000 units/reel, cathode lead oriented toward sprocket holes).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.89–6.51 V @ 60.5 mA - tight tolerance enables stable 6.2 V rail regulation in low-voltage logic supplies |
| Power Dissipation | 3.2 W @ cathode tab = 75 °C - requires thermal pad connection to PCB copper for full rating |
| Zener Impedance (ZZT) | 200 Ω @ IZT - limits AC ripple rejection capability in analog reference circuits |
| Leakage Current (IR) | <5 µA @ 4.0 V - ensures minimal standby power loss in battery-powered devices |
| ESD Rating | Class 3 (>16 kV HBM) - provides robust handling without external ESD protection in assembly |
| Package Height | Max 1.1 mm - enables use under compact shields or in ultra-thin handheld enclosures |
| Footprint Area | 8.45 mm² - 50% smaller than SMA, freeing PCB area for dense RF or sensor layouts |
Pinout & Package
The 1PMT5920BT3G uses the POWERMITE® (DO-216AA) surface-mount plastic package with integral heat sink tabs and full metallic bottom. Dimensions: 2.05 × 2.18 × 1.1 mm (L × W × H), cathode indicated by polarity band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to heat sink tab; must be soldered to thermal pad for rated 3.2 W dissipation |
| 2 | Anode | Standard anode connection; reverse-biased during Zener operation |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ5231BT1G | Same 6.2 V nominal, but 500 mW rating (vs. 3.2 W); SOD-123 package; RJA = 350 °C/W | Limited to low-power signal rails; unsuitable for >100 mA load regulation or thermal cycling | Select when board space permits larger thermal pads or power demand is ≤0.5 W |
| 1N4735A | 6.2 V, 1 W through-hole; TO-92 package; no Pb-free option; RJA = 150 °C/W | Requires through-hole assembly; incompatible with high-density SMT production; higher profile (4.5 mm) | Choose only for legacy repair, prototyping, or non-automated builds where reflow compatibility is not required |
Compared with MMSZ5231BT1G and 1N4735A, the 1PMT5920BT3G uniquely supports 3.2 W dissipation in a 1.1 mm profile with Pb-free compliance and Class 3 ESD - making it the only option for production-grade, high-density, thermally demanding portable designs.

FAQ
What is the exact Zener voltage tolerance for the 1PMT5920BT3G?
The 1PMT5920BT3G has a specified Zener voltage range of 5.89 V (minimum) to 6.51 V (maximum) at 60.5 mA test current and 25 °C junction temperature, corresponding to a ±4.8% tolerance around the nominal 6.2 V rating. This tolerance is guaranteed per the manufacturer's electrical characteristics table and applies under steady-state DC conditions with proper thermal management.
Can the 1PMT5920BT3G be used in place of a standard SMA-packaged Zener diode?
Yes, the 1PMT5920BT3G can replace SMA Zeners in many applications due to its identical thermal resistance to lead (RJanode = 35 °C/W) and superior thermal resistance to cathode tab (RJcathode = 23 °C/W), but its DO-216AA footprint differs. The 1PMT5920BT3G requires a dedicated land pattern per Case 457 dimensions - not a drop-in replacement - though it delivers equivalent thermal performance in 50% less PCB area.
What is the maximum continuous power dissipation for the 1PMT5920BT3G under real-world PCB conditions?
The 1PMT5920BT3G achieves its full 3.2 W rating only when the cathode tab (Pin 1) is thermally anchored to a ≥1 cm² copper pour at 75 °C. On standard FR-4 with minimum recommended pads, derating begins above 25 °C ambient at 4.0 mW/°C, limiting practical dissipation to ~1.8 W at 65 °C ambient - verified in the datasheet's Figure 1 derating curve.
Does the 1PMT5920BT3G support automated optical inspection (AOI) after reflow?
Yes, the 1PMT5920BT3G supports AOI: its cathode polarity band is clearly visible and contrast-enhanced per JEDEC DO-216AA standards, and the full metallic bottom ensures consistent solder joint reflectivity. The 1.1 mm height also avoids shadowing issues common with taller SMD packages during top-down camera inspection.
Is the 1PMT5920BT3G suitable for use in automotive infotainment systems?
The 1PMT5920BT3G meets AEC-Q200 stress test requirements for passive components and operates across −55 °C to +150 °C, making it technically viable for under-hood or dashboard-mounted infotainment modules. However, it is not AEC-Q101 qualified as a discrete semiconductor, so system-level validation per ISO/TS 16949 is required before deployment in safety-critical automotive applications.
