Product details
Overview
1PMT5928C/TR13 from Microsemi is a 13 V, ±1% 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-TAB. It serves as a precision voltage reference or overvoltage clamp in power supply feedback loops and regulator circuits.
For engineers reviewing the 1PMT5928C/TR13 datasheet, 1PMT5928C/TR13 pinout, 1PMT5928C/TR13 application, or 1PMT5928C/TR13 equivalent, key selection criteria include its tight 1% voltage tolerance, low 7.0 Ω Zener impedance, ESD rating >16 kV HBM, full metallic bottom for flux-free assembly, and compatibility with automatic insertion equipment.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable 13 V across its terminals under varying load conditions. Its design centers on thermal management via the integral heat sink locking tab and full metallic bottom, enabling reliable 3.0 W power handling without derating at board-level mounting temperatures up to +60°C at TAB 1.
The device exhibits low knee impedance (ZZK = 0.25 Ω) and tight regulation-verified at IZT = 28.8 mA-with reverse leakage limited to ≤1 µA at VR = 10.4 V and maximum Zener current IZM = 189.8 mA under 3.0 W dissipation limits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 13.0 V ±1% at IZT = 28.8 mA, TL = 30°C - enables precise voltage clamping or reference in feedback networks |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - supports high-energy transient suppression without external heatsinking |
| Dynamic Impedance (ZZT) | 7.0 Ω at IZT = 28.8 mA - ensures minimal output voltage variation under load current changes |
| Thermal Resistance | 30°C/W junction-to-TAB 1 - allows accurate thermal modeling for PCB copper pour sizing |
| ESD Rating | >16 kV per Human Body Model - provides robust handling and system-level ESD immunity |
| Reverse Leakage (IR) | ≤1 µA at VR = 10.4 V - guarantees low quiescent current in standby or sensing circuits |
| Knee Impedance (ZZK) | 0.25 Ω at IZK = 0.25 mA - ensures stable regulation even near breakdown threshold |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C13-7-F (Diodes Inc.) | 300 mW rating, SOT-23 package, 13 V ±5%, ZZT = 30 Ω at 5 mA | Limited to low-power signal-level clamping; not suitable for 3 W transient absorption | Select only for space-constrained, low-energy bias/reference use where thermal mass is sufficient |
| SMBJ13A (Littelfuse) | TVS diode, 13 V standoff, 200 W peak pulse, unidirectional, DO-214AA | Designed for fast transient suppression (8/20 µs), not precision DC regulation | Choose when surge immunity dominates over voltage accuracy; not interchangeable in feedback loops |
Compared with BZX84-C13-7-F and SMBJ13A, the 1PMT5928C/TR13 uniquely combines ±1% DC voltage accuracy, 3.0 W continuous dissipation, and thermal design optimized for PCB-mounted heat sinking-making it irreplaceable in regulated power supply references requiring both precision and power robustness.

FAQ
What is the Zener voltage tolerance for 1PMT5928C/TR13?
The "C" suffix in 1PMT5928C/TR13 denotes ±1% Zener voltage tolerance at IZT = 28.8 mA and TL = 30°C. This is tighter than the standard ±5% (B suffix) and supports high-accuracy regulation in feedback paths where voltage drift directly impacts system performance. The 1PMT5928C/TR13 achieves this via laser-trimmed wafer-level process control.
How is thermal management handled in the 1PMT5928C/TR13 package?
The 1PMT5928C/TR13 uses the Powermite® package's integral heat sink locking tab and full metallic bottom to conduct heat directly from the silicon junction to the PCB copper pour. With a measured thermal resistance of 30°C/W junction-to-TAB 1, proper pad design (≥100 mm² exposed copper) enables full 3.0 W dissipation at TAB 1 = 60°C-no additional heatsink required.
Can 1PMT5928C/TR13 replace through-hole Zener diodes like 1N5242B?
No-1PMT5928C/TR13 is not a drop-in replacement for 1N5242B. While both are 13 V Zeners, 1PMT5928C/TR13 is surface-mount (DO-216), rated for 3.0 W at TAB 1 = 60°C, and features a metallic thermal tab; 1N5242B is axial-lead, rated 0.5 W, and lacks thermal interface design. Board layout, thermal design, and assembly process differ fundamentally.
What does the "TR13" suffix indicate in 1PMT5928C/TR13?
The "TR13" suffix specifies tape-and-reel packaging per EIA-481 standard on a 13-inch reel containing 12,000 units. This format is optimized for high-volume SMT placement equipment and ensures consistent orientation (cathode TAB 1 leading) and moisture-sensitive level (MSL) compliance per J-STD-020. It does not affect electrical specifications of the 1PMT5928C/TR13 device itself.
Is 1PMT5928C/TR13 suitable for automotive applications?
The 1PMT5928C/TR13 meets AEC-Q200 stress test requirements for passive components when qualified per Microsemi's automotive-grade release (not standard commercial grade). Standard 1PMT5928C/TR13 is rated for -55°C to +150°C junction temperature and has >16 kV HBM ESD rating-key prerequisites-but automotive qualification requires explicit part number suffix "A" and PPAP documentation, which is not present in 1PMT5928C/TR13.
