Product details
Overview
1PMT5927AE3/TR13 from Microsemi is a 12 V, ±5% tolerance Zener diode in Powermite® surface-mount package, rated for 3.0 W DC power dissipation at TAB 1 = 60°C, with 6.5 Ω dynamic impedance at 31.2 mA test current and thermal resistance of 30°C/W junction-to-TAB1. It serves as precision voltage reference and overvoltage clamp in DC power rails of industrial control modules.
For engineers reviewing the 1PMT5927AE3/TR13 datasheet, 1PMT5927AE3/TR13 pinout, 1PMT5927AE3/TR13 application, or 1PMT5927AE3/TR13 equivalent, key selection criteria include zener voltage tolerance, power derating above 60°C, knee current (0.25 mA), reverse leakage (<1 µA at 9.1 V), and ESD rating (>16 kV HBM).
Technical Context
This device operates as a two-terminal voltage-regulating diode with sharp breakdown knee and low dynamic impedance, enabling stable clamping under transient load conditions. Its full metallic bottom and integral heat sink tab ensure reliable thermal conduction to PCB copper, supporting continuous 3.0 W dissipation when mounted on ≥1 sq-in 2-oz copper.
The Powermite® package (DO-216) uses TAB 1 as cathode terminal and supports automatic insertion; its molded construction and flux-free assembly compatibility meet IPC-A-610 Class 2 requirements for industrial electronics manufacturing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4742A | Same 12 V nominal, but TO-204AA (DO-41) through-hole package; 1 W rating; no metallic thermal tab | Requires manual soldering or wave soldering; unsuitable for high-power SMT designs | Select only if legacy through-hole assembly or lower power (≤1 W) operation is acceptable |
| BZX84-C12 | SOT-23 package; 12 V ±5%; 300 mW rating; 30 Ω dynamic impedance at 5 mA | Limited to low-current bias/reference use; cannot sustain 3.0 W clamping loads | Choose for space-constrained low-power bias networks where thermal performance is secondary |

FAQ
What is the zener voltage tolerance for 1PMT5927AE3/TR13?
The 1PMT5927AE3/TR13 has a standard zener voltage tolerance of ±5% at 12 V nominal, measured at 31.2 mA test current with TAB 1 held at 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D, but the base part number 1PMT5927AE3/TR13 specifies ±5%. This tolerance directly impacts the allowable clamping window in overvoltage protection circuits.
How is thermal management implemented for 1PMT5927AE3/TR13 in PCB layout?
The 1PMT5927AE3/TR13 relies on TAB 1 as its primary thermal path; PCB layout must include a dedicated thermal pad connected to ≥1 square inch of 2-ounce copper to achieve the full 3.0 W rating at 60°C. The Powermite® package's full metallic bottom and locking tab require solder paste stencil design with 70–80% aperture ratio to ensure void-free thermal interface. Without proper copper area, power derating is required per the 30°C/W junction-to-TAB1 thermal resistance.
Does 1PMT5927AE3/TR13 support automated SMT assembly?
Yes, the 1PMT5927AE3/TR13 is fully compatible with automated insertion equipment due to its standardized DO-216 footprint, lightweight (0.016 g), and symmetric lead geometry. It ships in EIA-481 tape-and-reel format (7-inch reel, 3,000 pieces), meeting IPC-7351B land pattern guidelines. The integral locking tab enhances placement stability during pick-and-place, reducing misalignment risk in high-volume production.
What is the maximum reverse leakage current for 1PMT5927AE3/TR13?
The maximum reverse leakage current for 1PMT5927AE3/TR13 is 1 µA at 9.1 V reverse voltage (75% of nominal 12 V zener voltage), tested at TL = 30°C. This low leakage ensures minimal quiescent current draw in always-on monitoring circuits, such as microcontroller reset supervisors or battery-backed real-time clocks, where standby power budget is critical.
Can 1PMT5927AE3/TR13 be used as a voltage reference in precision analog circuits?
The 1PMT5927AE3/TR13 is not recommended as a precision voltage reference due to its ±5% initial tolerance and 6.5 Ω dynamic impedance, which cause output voltage shifts with load current changes. It is optimized for clamping and coarse regulation-not low-drift reference applications. For precision references, consider bandgap-based ICs like the REF5012. The 1PMT5927AE3/TR13 functions best in robust overvoltage protection roles where absolute accuracy is secondary to power handling and reliability.
