Product details
Overview
1PMT5928AE3/TR13 from Microsemi is a 13 V, ±5% tolerance surface-mount Zener diode in the Powermite® package, rated for 3.0 W DC power dissipation at TAB 1 = 60°C, with 7.0 Ω dynamic impedance at 28.8 mA test current and thermal resistance of 30°C/W junction-to-TAB1. It serves as a precision voltage reference or overvoltage clamp in power supply regulation and ESD-protected I/O circuits.
For engineers reviewing the 1PMT5928AE3/TR13 datasheet, 1PMT5928AE3/TR13 pinout, 1PMT5928AE3/TR13 application, or 1PMT5928AE3/TR13 equivalent, key selection criteria include its 13 V nominal Zener voltage, 3.0 W power handling in a DO-216 footprint, low 7.0 Ω dynamic impedance, >16 kV HBM ESD rating, and full metallic bottom for flux-free reflow assembly.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across load variations, with knee current (IZK) of 0.25 mA and knee impedance (ZZK) of 550 Ω - enabling reliable regulation even at low bias currents. Its DO-216 package features a cathode-marked TAB 1 and integral heat sink locking tab for mechanical retention and thermal conduction.
The device is characterized at TL = 30°C with Zener voltage measured 20 seconds after DC current application; dynamic impedance is derived using 60 Hz RMS AC current equal to 10% of IZT. Maximum junction temperature is +150°C, supporting operation in industrial and automotive under-hood environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 13 V ±5% at IZT = 28.8 mA - defines primary regulation point with tight production control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5349B | Same 13 V nominal VZ, but DO-204AL (DO-41) through-hole package; 1.0 W rating; higher ZZT (10 Ω) | Requires PCB hole drilling and wave soldering; unsuitable for high-density SMT layouts | Select only when legacy through-hole assembly or lower-cost manual repair is required |
| BZX84-C13 | SOT-23 package; 300 mW rating; ±5% tolerance; 30 Ω ZZT; no metallic thermal tab | Limited to low-power signal-level clamping; cannot handle >100 mA surge currents | Choose for space-constrained logic-level protection where thermal performance is secondary |
Compared with 1N5349B and BZX84-C13, the 1PMT5928AE3/TR13 uniquely combines 3.0 W power handling, DO-216 SMT compatibility, and 30°C/W thermal resistance - making it the only option capable of replacing both in high-reliability, thermally demanding applications without layout redesign.

FAQ
What is the Zener voltage tolerance for 1PMT5928AE3/TR13?
The 1PMT5928AE3/TR13 has a standard Zener voltage tolerance of ±5% at 13 V nominal, measured at IZT = 28.8 mA with TAB 1 held at 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D respectively, but the E3 suffix indicates the standard ±5% version. This tolerance is maintained across the full operating temperature range of –55°C to +150°C.
How is thermal performance specified for 1PMT5928AE3/TR13?
The 1PMT5928AE3/TR13 specifies a thermal resistance of 30°C/W junction-to-TAB1, meaning each watt of dissipated power raises the junction temperature by 30°C above the TAB 1 temperature. With a maximum rated power of 3.0 W at TAB 1 = 60°C, this yields a theoretical max junction temperature of 150°C - matching its absolute maximum rating and confirming safe operation under full load in properly designed thermal layouts.
Can 1PMT5928AE3/TR13 be used in place of through-hole Zeners like 1N5349B?
No - the 1PMT5928AE3/TR13 is not a drop-in replacement for 1N5349B due to fundamental differences in package (DO-216 vs. DO-41), power rating (3.0 W vs. 1.0 W), and thermal path (metallic TAB 1 vs. axial leads). While both share 13 V nominal Zener voltage, substituting requires PCB redesign to accommodate the surface-mount footprint and verify thermal margin under peak load conditions.
What does the "TR13" suffix indicate in 1PMT5928AE3/TR13?
The "TR13" suffix in 1PMT5928AE3/TR13 denotes tape-and-reel packaging per EIA Standard 481, with 13-inch reels containing 12,000 units. This format is optimized for high-volume SMT assembly lines and differs from the 7-inch reel option (TR7) holding 3,000 pieces. The "E3" portion specifies ±5% voltage tolerance and RoHS-compliant finish.
Is 1PMT5928AE3/TR13 suitable for automotive applications?
Yes - the 1PMT5928AE3/TR13 meets automotive-grade requirements with a junction temperature range of –55°C to +150°C, >16 kV HBM ESD rating, and robust DO-216 construction featuring flux-free metallic bottom and integral heat sink tab. It is commonly deployed in body control modules, LIN bus protection, and sensor supply regulation where thermal stability and transient immunity are critical.
