Product details
Overview
1PMT5936E3/TR13 from Microsemi is a 30 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 12.5 mA test current, 28 Ω dynamic impedance, and 1 µA max reverse leakage at 22.8 V. It serves as a precision voltage reference or overvoltage clamp in DC power rails of industrial control modules.
For engineers reviewing the 1PMT5936E3/TR13 datasheet, 1PMT5936E3/TR13 pinout, 1PMT5936E3/TR13 application, or 1PMT5936E3/TR13 equivalent, key selection criteria include zener voltage tolerance, thermal resistance (30°C/W junction-to-TAB), ESD rating (>16 kV HBM), tape-and-reel packaging (EIA-481, 13-inch reel, 12,000 pcs), and compatibility with automatic insertion equipment.
Technical Context
This Zener diode operates in reverse breakdown mode to regulate or clamp voltage with stable performance across -55°C to +150°C junction temperature range. Its full metallic bottom eliminates solder flux entrapment, and the integral locking tab provides mechanical retention and thermal conduction to PCB copper.
The device exhibits low knee impedance (750 Ω at IZK = 0.25 mA) and tight dynamic impedance (28 Ω at IZT = 12.5 mA), enabling reliable regulation under varying load conditions. Reverse leakage remains ≤1 µA up to 22.8 V, supporting low-power standby circuit integrity.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor 1N5357B | Same 30 V nominal, but DO-204AL package; higher thermal resistance (65°C/W); no locking tab | Limited to lower-power or less thermally demanding layouts; not optimized for automatic insertion | Select when legacy through-hole footprint compatibility is required and thermal margin is sufficient |
| Vishay SZ1SMB5936BT3G | 30 V, SOD-123 package; 1.5 W rating; 40 Ω dynamic impedance; 30°C/W junction-to-case | Suitable only for <1.5 W clamping; requires different PCB pad design and thermal relief strategy | Choose for space-constrained designs where 3.0 W capability is unnecessary and cost is prioritized |

FAQ
What is the Zener voltage tolerance for 1PMT5936E3/TR13?
The 1PMT5936E3/TR13 has a standard Zener voltage tolerance of ±5% at 30 V, measured at 12.5 mA test current with TAB 1 held at 30°C. Tighter tolerances (±2% and ±1%) are available with suffixes C and D respectively, but the E3 suffix denotes the standard ±5% version. This tolerance directly impacts voltage-clamp accuracy in overvoltage protection circuits.
How is thermal management handled in the 1PMT5936E3/TR13 package?
The 1PMT5936E3/TR13 uses a Powermite® package with a full metallic bottom and integral locking tab that serves as both mechanical anchor and primary thermal path. Its specified thermal resistance is 30°C/W junction-to-TAB, meaning effective heat transfer relies on soldering TAB 1 to a sufficiently sized copper pad. This design eliminates flux entrapment and supports stable 3.0 W operation at TAB 1 = 60°C.
Is the 1PMT5936E3/TR13 compatible with standard SMT assembly processes?
Yes, the 1PMT5936E3/TR13 is explicitly designed for compatibility with automatic insertion equipment and standard reflow soldering. Its geometry, weight (≈0.016 g), and DO-216 outline conform to EIA-481 tape-and-reel standards (13-inch reel, 12,000 pcs). The locking tab enhances placement stability, and the full metallic bottom prevents solder voids-key requirements for high-yield SMT lines.
What is the maximum reverse leakage current for 1PMT5936E3/TR13?
The maximum reverse leakage current for 1PMT5936E3/TR13 is 1 µA at a reverse voltage of 22.8 V, measured at TL = 30°C. This low leakage supports energy-efficient operation in always-on monitoring circuits and preserves signal integrity in high-impedance reference paths, especially critical in battery-powered medical and industrial sensor nodes.
Does the 1PMT5936E3/TR13 meet industry ESD standards?
Yes, the 1PMT5936E3/TR13 is rated for >16 kV per Human Body Model (HBM), exceeding common industrial ESD immunity requirements. This robustness is achieved through internal process design and packaging, allowing safe handling during board assembly and field service without additional external protection-reducing BOM count and layout complexity in end equipment.
