Product details
Overview
1N5354BE3/TR13 from Microsemi is a 5 W axial-leaded silicon Zener diode with a nominal regulation voltage of 17 V, ±5% tolerance (B suffix), 70 mA maximum Zener test current (IZT), 2.5 Ω maximum dynamic impedance (ZZ), and 5.8 A maximum Zener current (IZM) when adequately heat-sunk. It regulates voltage in power supply reference and overvoltage protection circuits across industrial and telecom systems.
For engineers reviewing the 1N5354BE3/TR13 datasheet, 1N5354BE3/TR13 pinout, 1N5354BE3/TR13 application, or 1N5354BE3/TR13 equivalent, key selection criteria include its 17 V Zener voltage, 5 W steady-state power rating at TL < 25°C, low 2.5 Ω dynamic impedance, -65°C to +150°C operating temperature range, and RoHS-compliant e3 termination.
Technical Context
This device operates as a voltage reference by maintaining a stable reverse-biased breakdown voltage across a broad current range (10–50% of IZM). Its thermal resistance is 25 °C/W junction-to-lead at 3/8" lead length, enabling high-current operation with minimal derating when mounted with adequate heat sinking.
The 1N5354BE3/TR13 exhibits 0.35 V maximum voltage regulation (ΔVZ) between 10% and 50% of IZM, and 500 Ω maximum dynamic knee impedance (ZZK) at 1.0 mA - confirming tight regulation at low bias currents typical in precision reference and sensing applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5354B (non-e3, tape-and-reel not specified) | Same 17 V ±5%, 5 W rating, but lead finish is tin-lead; no RoHS compliance | Not suitable for lead-free manufacturing; requires exemption or alternate process validation | Select only for legacy repair or non-RoHS programs where tin-lead solder is used |
| MMSZ5246B-TP (Micro Commercial Components) | Surface-mount SOD-123 package; 17 V ±5%, 500 mW - 1/10th the power rating | Limited to low-power biasing; cannot replace 1N5354BE3/TR13 in 5 W regulation roles | Use only in space-constrained PCBs where thermal budget permits ≤0.5 W dissipation |
Compared with 1N5354BE3/TR13, the 1N5354B lacks RoHS compliance and standardized tape-and-reel packaging, while MMSZ5246B-TP trades axial-leaded robustness and 5 W capability for miniaturization - making neither a drop-in replacement, but both viable for context-specific alternatives.

FAQ
What is the Zener voltage tolerance of the 1N5354BE3/TR13?
The 1N5354BE3/TR13 has a Zener voltage tolerance of ±5%, indicated by the "B" suffix in its part number. This means its measured breakdown voltage at 70 mA test current falls within 16.15 V to 17.85 V at 25°C lead temperature. The e3 suffix confirms RoHS compliance, and TR13 denotes tape-and-reel packaging per EIA-296 standards - all consistent with Microsemi's published electrical characteristics table.
Can the 1N5354BE3/TR13 be used without a heatsink?
Yes, the 1N5354BE3/TR13 can operate at up to 1.47 W continuously without a heatsink when mounted on a standard FR4 PCB with 4 mm² copper pads and 1 mm trace width, per its thermal resistance spec of 85°C/W junction-to-ambient. For full 5 W operation, it requires mounting with 3/8" lead length and sufficient thermal mass or external heatsinking to maintain TL < 25°C - as confirmed in Microsemi's derating curve (Figure 1).
What does the "TR13" suffix mean in 1N5354BE3/TR13?
The "TR13" suffix in 1N5354BE3/TR13 indicates tape-and-reel packaging per EIA-296 standard, with 1,300 units per reel. This format supports automated pick-and-place assembly and is distinct from bulk or ammo-pack options. The "e3" portion confirms RoHS-compliant matte-tin plating, and "B" specifies ±5% Zener voltage tolerance - all verified in Microsemi's official datasheet revision D (2008).
How does the 1N5354BE3/TR13 perform under surge conditions?
The 1N5354BE3/TR13 is rated for a maximum non-recurrent surge current (IZSM) of 5.8 A, defined as a single 8.3 ms half-sine waveform. This allows it to absorb transient energy in overvoltage protection circuits without degradation. Its ability to clamp at ≤17.6 V under surge - combined with 0.5 μA leakage at 12.2 V - makes it suitable for protecting sensitive 17–24 V system rails, as documented in Microsemi's Electrical Characteristics table.
Is the 1N5354BE3/TR13 suitable for automotive applications?
Yes, the 1N5354BE3/TR13 is suitable for automotive applications due to its -65°C to +150°C operating and storage temperature range, MIL-STD-750 qualified ESD immunity, and moisture sensitivity level 1 (no dry pack required). While not AEC-Q200 qualified out-of-box, its construction and screening options (e.g., JANTXV prefix variants) support use in engine control, body electronics, and infotainment power rails where robust Zener regulation is needed.
