Product details
Overview
1PMT5956CE3/TR13 from Microsemi is a 200 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 1.9 mA test current (IZT), 1200 Ω dynamic impedance (ZZT), and <1 µA reverse leakage at 152 V. It serves as a precision voltage reference or overvoltage clamp in high-reliability power supply feedback loops.
For engineers reviewing the 1PMT5956CE3/TR13 datasheet, 1PMT5956CE3/TR13 pinout, 1PMT5956CE3/TR13 application, or 1PMT5956CE3/TR13 equivalent, key selection criteria include its 200 V zener voltage, 3.0 W thermal capability with metallic tab heat sinking, ESD rating >16 kV HBM, DO-216 mechanical outline, and compatibility with EIA-481 tape-and-reel automated assembly.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage regulation across varying load currents. Its Powermite® package integrates a full metallic bottom and locking tab that directly conducts heat from the junction to the PCB copper pour or heatsink, enabling 3.0 W dissipation without external heatsinking when mounted per spec.
The device exhibits low knee impedance (ZZK = 0.25 Ω) and tight voltage tolerance (±5%, with C/D suffixes for 2%/1%), supporting accurate clamping in transient suppression and reference circuits. Reverse leakage remains below 1 µA up to 152 V, ensuring minimal standby power loss in high-impedance bias networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 200 V ±5% - precise clamping threshold for 152–200 V system protection |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - enables high-energy transient absorption without derating |
| Test Current (IZT) | 1.9 mA - operating point where VZ is specified; defines minimum bias for regulation |
| Dynamic Impedance (ZZT) | 1200 Ω - voltage change per mA deviation from IZT; impacts regulation stability under load shifts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMCJ200A | TVS diode (unidirectional), 200 V standoff, 3.0 kW peak pulse power, higher clamping voltage (~324 V) | Designed for surge suppression, not precision regulation; lacks stable DC Zener characteristics | Select for transient-only protection where DC regulation is unnecessary |
| 1N5388B | Through-hole 200 V Zener, 5 W rating, TO-204AA (DO-41) package, no integrated heat sink tab | Requires external heatsinking for >1 W; incompatible with SMT automation | Select only if through-hole assembly is mandated and thermal budget exceeds 3.0 W |
Compared with SMCJ200A and 1N5388B, the 1PMT5956CE3/TR13 uniquely combines SMT compatibility, integrated thermal management, and stable DC regulation at 200 V-making it optimal for space-constrained, high-reliability power control designs requiring both precision and ruggedness.

FAQ
What is the zener voltage tolerance for 1PMT5956CE3/TR13?
The 1PMT5956CE3/TR13 has a standard zener voltage tolerance of ±5% at 200 V, as indicated by the "C" suffix in the part number. This tolerance is verified at IZT = 1.9 mA and TAB 1 temperature of 30°C. Tighter tolerances (2% and 1%) are available with suffixes "C" and "D", respectively, but the "CE3" variant specifies ±5%.
Can 1PMT5956CE3/TR13 be used in place of a through-hole 200 V Zener like 1N5388B?
The 1PMT5956CE3/TR13 is not a drop-in replacement for 1N5388B due to different package (DO-216 vs. DO-41), thermal path (integrated tab vs. lead-frame only), and power derating behavior. While both regulate at 200 V, the 1PMT5956CE3/TR13 requires PCB thermal pad design for 3.0 W operation, whereas 1N5388B needs external heatsinking above 1 W.
What does the "E3" in 1PMT5956CE3/TR13 signify?
The "E3" denotes tape-and-reel packaging per EIA-481 standard, with 3,000 units per 7-inch reel. The "TR13" suffix confirms this configuration. This format ensures compatibility with high-speed SMT placement equipment and supports automated manufacturing workflows without manual handling.
How is thermal performance characterized for 1PMT5956CE3/TR13?
Thermal performance of the 1PMT5956CE3/TR13 is defined by a junction-to-TAB1 thermal resistance of 30°C/W. Since TAB 1 is the cathode and primary heat path, effective thermal design requires soldering TAB 1 to a minimum 100 mm² copper area on the PCB. Derating begins above TAB 1 = 60°C, where maximum power drops linearly to zero at 150°C.
Is 1PMT5956CE3/TR13 suitable for automotive applications?
The 1PMT5956CE3/TR13 meets AEC-Q200 stress test requirements for passive components and operates across –55°C to +150°C junction temperature. However, Microsemi's official qualification data for automotive use applies only to specific part numbers with "AEC-Q200" marking; this variant is qualified for industrial and telecom use, and automotive deployment requires additional system-level validation.
