Product details
Overview
SMBG5341B/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 6.2 V, ±5% tolerance (B suffix), 200 mA test current (IZT), 1.0 Ω dynamic impedance (ZZT), and maximum regulator current of 765 mA. It operates in reverse-biased regulation mode for voltage reference and overvoltage protection in power supply rails.
For engineers reviewing the SMBG5341B/TR13 datasheet, SMBG5341B/TR13 pinout, SMBG5341B/TR13 application, or SMBG5341B/TR13 equivalent, key selection criteria include Zener voltage accuracy, surge current capability (12.4 A IZSM), thermal resistance (90 °C/W junction-to-ambient), and DO-215AA gull-wing package compatibility with high-density PCB layouts.
Technical Context
This device functions as a precision voltage reference by maintaining stable reverse breakdown at 6.2 V across operating currents from 1 mA to 765 mA. Its low dynamic impedance (1.0 Ω) ensures minimal voltage variation under load transients, while the 12.4 A non-repetitive surge rating supports transient suppression in DC power lines.
The SMBG5341B/TR13 uses silicon PN-junction construction in a void-free thermosetting epoxy case (UL94V-0), with cathode indicated by band polarity and RoHS-compliant matte-tin plating. Thermal performance is specified for FR4 board mounting with recommended footprint, delivering 5.0 W dissipation only when lead temperature (TL) remains below 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V ±5% at 200 mA - defines precise regulation point for feedback loops and reference circuits |
| Power Dissipation (PD) | 5.0 W @ TL < 25 °C - requires thermal management via copper pour or heatsinking on lead |
| Dynamic Impedance (ZZT) | 1.0 Ω @ 200 mA - ensures <10 mV output shift per 10 mA load change in regulation zone |
| Max Surge Current (IZSM) | 12.4 A (8.3 ms half-sine) - clamps short-duration transients without failure |
| Junction Temp Range | –65 °C to +150 °C - supports operation in automotive under-hood and industrial control environments |
| Thermal Resistance RθJA | 90 °C/W on FR4 (1 oz Cu) - dictates minimum copper area needed to sustain full power |
| Reverse Leakage (IR) | 1.0 µA @ 3.0 V - negligible current draw in standby, critical for battery-backed systems |
Pinout & Package
DO-215AA gull-wing surface-mount package with two terminals: anode and cathode. Cathode identified by molded band; device operated with banded end positive relative to anode. Package dimensions: 4.06–4.57 mm length (B), 3.30–3.94 mm width (C), 1.96–2.10 mm height (A).

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5341B | Axial-leaded T-18 package; identical electrical specs but higher RθJA (120 °C/W) and no gull-wing visibility | Through-hole assembly; unsuitable for high-density SMT boards | Select when legacy through-hole production or manual repair is required |
| SMBJ5341B | DO-214AA J-bend package; same VZ/IZT/IZM but 1.5 Ω ZZT and 11.5 A IZSM | Compatible footprint on same PCB land pattern but different leadform geometry | Choose for designs already using SMBJ-series footprints or requiring slightly higher surge margin |
Compared with SMBG5341B/TR13, 1N5341B demands through-hole assembly and offers inferior thermal performance, while SMBJ5341B trades 0.5 Ω higher impedance for J-bend mount flexibility-neither is pin-compatible, but both serve equivalent regulation roles in matching voltage and power classes.

FAQ
What is the Zener voltage tolerance for SMBG5341B/TR13?
The "B" suffix in SMBG5341B/TR13 denotes ±5% Zener voltage tolerance, meaning its breakdown voltage is guaranteed between 5.89 V and 6.51 V at 200 mA test current and 25 °C. This tolerance is verified per JEDEC test methods and applies across the full operating temperature range of –65 °C to +150 °C.
Can SMBG5341B/TR13 replace 1N5341B in existing designs?
Yes, SMBG5341B/TR13 is electrically equivalent to 1N5341B per Microsemi documentation, sharing identical VZ, IZT, IZM, and ZZT specifications. However, the SMBG5341B/TR13 uses DO-215AA gull-wing packaging versus the axial T-18 of 1N5341B, so PCB layout and assembly process must be updated accordingly.
What is the maximum continuous power dissipation for SMBG5341B/TR13?
SMBG5341B/TR13 delivers 5.0 W continuous power dissipation only when lead temperature (TL) is maintained below 25 °C. At ambient temperature (TA = 25 °C) on FR4 with recommended footprint, derated power drops to 1.38 W due to 90 °C/W junction-to-ambient thermal resistance-adequate heatsinking is required for full-power operation.
How does the DO-215AA package benefit automated assembly of SMBG5341B/TR13?
The DO-215AA gull-wing package of SMBG5341B/TR13 provides coplanar leads that enable reliable solder paste release, self-centering during reflow, and post-reflow optical inspection of solder fillets-critical for high-yield manufacturing of compact power management modules where SMBG5341B/TR13 is commonly deployed.
Is SMBG5341B/TR13 suitable for automotive applications?
Yes, SMBG5341B/TR13 is qualified for automotive use with a junction temperature range of –65 °C to +150 °C, moisture sensitivity Level 1 (no dry pack), and robust surge capability (12.4 A, 8.3 ms). It meets requirements for engine control unit voltage references and body electronics overvoltage clamping where SMBG5341B/TR13 is specified.
