Product details
Overview
1N5356BE3/TR13 from Microsemi is a 5 W, 19 V ±5% axial-leaded silicon Zener diode optimized for voltage regulation in power supply reference and overvoltage protection circuits. It delivers stable regulation at 19 V with 3.0 Ω dynamic impedance (ZZ), 65 mA test current (IZT), and supports up to 5.3 A maximum surge current (IZSM) under 8.3 ms half-sine stress.
For engineers reviewing the 1N5356BE3/TR13 datasheet, 1N5356BE3/TR13 pinout, 1N5356BE3/TR13 application, or 1N5356BE3/TR13 equivalent, key selection criteria include its ±5% tolerance (B suffix), RoHS-compliant matte-tin plating (e3), tape-and-reel packaging (TR13), and thermal resistance of 25 °C/W junction-to-lead at 10 mm lead length.
Technical Context
This Zener operates as a two-terminal shunt regulator, maintaining a stable 19 V reverse breakdown voltage across a broad operating current range (10–500 mA). Its low dynamic impedance (3.0 Ω) and tight voltage regulation (ΔVZ = 0.40 V between 10% and 50% IZM) ensure minimal output variation under load transients.
The device features a T-18 axial package with cathode band marking, rated for -65°C to +150°C operation, and achieves 5.0 W steady-state dissipation at TL < 25°C with adequate heat sinking-enabling use in industrial DC-DC feedback loops and analog reference rails where precision and surge resilience are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 19 V ±5% - precise regulation point for 18–19.4 V reference applications |
| Test Current (IZT) | 65 mA - nominal operating point where VZ and ZZ are specified |
| Dynamic Impedance (ZZ) | 3.0 Ω - low AC resistance ensures minimal voltage shift under current ripple |
| Max Surge Current (IZSM) | 5.3 A (8.3 ms half-sine) - withstands transient overvoltage events without failure |
| Power Dissipation | 5.0 W at TL < 25°C - requires thermal management beyond 25°C per derating curve |
| Reverse Leakage (IR) | 0.5 μA @ 14.4 V - negligible standby current in high-impedance bias networks |
| Thermal Resistance | 25 °C/W junction-to-lead (10 mm lead length) - enables predictable thermal design with simple heatsinking |
Pinout & Package
Package: T-18 axial-leaded plastic case (void-free UL94V-0 epoxy), cathode indicated by colored band. Leads are annealed matte-tin plated (RoHS-compliant per e3 suffix), solderable per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to circuit common; reverse-biased operation requires cathode at higher potential |
| Cathode | Regulated output node | Banded end; held at stable 19 V relative to anode during conduction; used for feedback or clamping |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC-registered 5 W Zener | Industry-standard reliability and interchangeability in legacy and new designs |
| ±5% voltage tolerance (B suffix) | Guarantees 18.05–19.95 V regulation without binning or calibration |
| Moisture sensitivity Level 1 | No dry pack required-reduces handling cost and eliminates bake-out prior to assembly |
| Nonsensitive to ESD (MIL-STD-750 Method 1020) | Robust handling in standard manufacturing environments without special ESD controls |
| Tape-and-reel packaging (TR13) | Enables automated pick-and-place assembly; TR13 denotes 13-inch reel standard per EIA-296 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5356B | No TR13 tape-and-reel; bulk packaging only; same electrical specs and e3 RoHS compliance | Not suitable for automated SMT assembly; requires manual or vibratory feed placement | Select 1N5356B only for prototyping or low-volume hand-soldered builds |
| MMBZ5247BS-7-F | Surface-mount SOD-123 package; 19 V ±5%, but rated at 0.5 W (not 5 W); 30 Ω ZZ | Limited to low-power signal-level clamping or biasing; cannot replace 1N5356BE3/TR13 in power regulation | Choose MMBZ5247BS-7-F only for space-constrained PCBs where power dissipation ≤0.5 W is sufficient |
Compared with 1N5356B and MMBZ5247BS-7-F, the 1N5356BE3/TR13 uniquely combines 5 W power handling, axial-leaded mechanical robustness, RoHS compliance, and tape-and-reel automation readiness-making it the sole option for high-reliability, medium-power industrial regulation requiring JEDEC-standard form factor and volume manufacturability.

FAQ
What is the Zener voltage tolerance of the 1N5356BE3/TR13?
The 1N5356BE3/TR13 has a ±5% Zener voltage tolerance, confirmed by the "B" suffix in its part number per Microsemi's datasheet. This means its nominal 19 V breakdown voltage is guaranteed between 18.05 V and 19.95 V at 65 mA test current and 25°C lead temperature. The e3 suffix indicates RoHS compliance but does not affect tolerance.
Does the 1N5356BE3/TR13 require dry packing before reflow soldering?
No, the 1N5356BE3/TR13 has IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it is not hygroscopic and requires no dry pack or baking prior to soldering. Its void-free thermosetting epoxy body and matte-tin plating support standard reflow profiles up to 260°C for 10 seconds without preconditioning.
What is the maximum continuous power dissipation for the 1N5356BE3/TR13?
The 1N5356BE3/TR13 is rated for 5.0 W steady-state power dissipation when lead temperature (TL) is maintained below 25°C, measured at 10 mm from the body. Derating is required above 25°C per Figure 1 in the datasheet-e.g., ~3.5 W at TL = 50°C. On FR4 board with 4 mm² copper pads, max ambient-rated power drops to 1.47 W at TA = 25°C.
Can the 1N5356BE3/TR13 be used as a direct replacement for the 1N5356B?
Yes-the 1N5356BE3/TR13 is functionally identical to the 1N5356B in all electrical and thermal specifications. The e3 suffix adds RoHS compliance, and TR13 denotes tape-and-reel packaging; both share the same T-18 axial package, ±5% tolerance, 19 V rating, and 5 W power capability. No circuit or layout changes are needed.
What is the surge current rating of the 1N5356BE3/TR13 and how is it defined?
The 1N5356BE3/TR13 has a maximum non-recurrent surge current (IZSM) of 5.3 A, defined as the peak value of an 8.3 ms half-sine waveform per Note 5 in the datasheet. This rating reflects its ability to absorb transient energy without parametric shift or failure-critical for protecting downstream components during load dump or inductive kick events.
