Product details
Overview
1PMT5953C/TR13 from Microsemi is a 150 V, ±1% tolerance Zener diode in Powermite® surface-mount package with 3.0 W power dissipation, 2.5 mA test current, and 600 Ω dynamic impedance at 20°C case temperature - used for precision voltage regulation and overvoltage protection in DC power rails.
For engineers reviewing the 1PMT5953C/TR13 datasheet, 1PMT5953C/TR13 pinout, 1PMT5953C/TR13 application, or 1PMT5953C/TR13 equivalent, key selection criteria include Zener voltage tolerance (±1%), thermal resistance (30°C/W), ESD rating (>16 kV HBM), reverse leakage (<1 µA at 114 V), and compatibility with automated SMT assembly.
Technical Context
This Zener diode operates as a two-terminal voltage reference device with cathode designated by TAB 1, requiring no external biasing. Its full metallic bottom and integral heat sink locking tab enable efficient thermal conduction to the PCB pad while eliminating solder flux entrapment during reflow.
The device is characterized at TL = 30°C with VZ measured 20 seconds after DC current application; dynamic impedance is derived using 60 Hz RMS AC current equal to 10% of IZT. Junction-to-TAB1 thermal resistance is 30°C/W, supporting stable regulation under sustained 3.0 W dissipation when TAB1 is held at ≤60°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage | 150 V ±1% - tight tolerance enables accurate clamping in high-voltage protection circuits |
| Power Dissipation | 3.0 W at TAB1 = 60°C - supports robust transient suppression without derating in compact layouts |
| Test Current | 2.5 mA - defines nominal operating point for VZ specification and impedance measurement |
| Dynamic Impedance | 600 Ω at IZT - indicates moderate regulation stiffness; suitable for non-critical reference applications |
| Reverse Leakage | <1 µA at 114 V - ensures low standby power loss in high-impedance sensing or hold-up circuits |
| ESD Rating | >16 kV HBM - provides inherent handling robustness without additional protection circuitry |
| Thermal Resistance | 30°C/W junction-to-TAB1 - requires ≥100 mm² copper pad for full 3.0 W operation at ambient |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMF150A (ON Semiconductor) | 150 V, ±5%, 1.0 W, SOD-123FL package, 1000 Ω Zzt | Lower power rating limits use to short-duration transients only | Select when board space is constrained and peak pulse energy < 0.1 J |
| BZX84-C150 (Diodes Inc.) | 150 V, ±5%, 300 mW, SOT-23, 1200 Ω Zzt | Not rated for continuous 3.0 W operation; unsuitable for sustained clamping | Choose only for low-power bias/reference where thermal mass is limited |
Compared with SMF150A and BZX84-C150, the 1PMT5953C/TR13 delivers 3× higher continuous power handling, 2× lower dynamic impedance, and ±1% tolerance - making it uniquely suited for industrial-grade voltage clamping where thermal stability and precision outweigh footprint constraints.

FAQ
What is the Zener voltage tolerance for 1PMT5953C/TR13?
The "C" suffix in 1PMT5953C/TR13 denotes ±1% Zener voltage tolerance at 2.5 mA test current and 30°C case temperature. This is tighter than the standard ±5% (B suffix) and supports precision clamping without post-production calibration. The tolerance remains valid across the full operating junction temperature range of –55°C to +150°C per the datasheet.
How is thermal performance defined for 1PMT5953C/TR13?
1PMT5953C/TR13 has a junction-to-TAB1 thermal resistance of 30°C/W. Full 3.0 W power dissipation is rated only when TAB1 (cathode) is maintained at ≤60°C - typically achieved with ≥100 mm² of 2-oz copper connected directly to the tab. Derating is required above 60°C tab temperature per the published thermal curve.
Is 1PMT5953C/TR13 compatible with lead-free reflow processes?
Yes, 1PMT5953C/TR13 is qualified for standard lead-free reflow profiles including JEDEC J-STD-020, with peak temperatures up to 260°C. Its Powermite® package uses matte tin-plated leads and a molded compound rated for repeated thermal cycling. No special prebake or moisture sensitivity level (MSL) handling is required.
What does the "TR13" suffix indicate in 1PMT5953C/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 feeding and tension control during automated assembly - distinct from the 7-inch reel (TR7) option holding 3,000 pieces.
Can 1PMT5953C/TR13 be used as a voltage reference in precision analog circuits?
1PMT5953C/TR13 can serve as a coarse voltage reference in non-critical analog circuits due to its ±1% tolerance and low 1 µA max reverse leakage at 114 V. However, it lacks temperature compensation and exhibits typical Zener voltage drift of ±0.08%/°C - so it is not recommended for high-accuracy references where TC or long-term stability matters more than cost or size.
