Product details
Overview
1N5340AE3/TR13 from Microsemi is a 6.0 V, ±10% tolerance, 5 W axial-leaded silicon Zener diode optimized for voltage regulation in power supply feedback loops, overvoltage protection circuits, and reference voltage generation. It delivers stable regulation at 200 mA test current with 1.0 Ω dynamic impedance and operates across –65°C to +150°C.
For engineers reviewing the 1N5340AE3/TR13 datasheet, 1N5340AE3/TR13 pinout, 1N5340AE3/TR13 application, or 1N5340AE3/TR13 equivalent, key selection criteria include its 6.0 V nominal Zener voltage, ±10% tolerance (A suffix), 5 W steady-state power rating at lead temperature <25°C, and RoHS-compliant matte-tin plating per MIL-STD-750.
Technical Context
This discrete Zener diode functions as a two-terminal voltage reference device, operating in reverse breakdown mode with cathode-banded polarity. Its regulation performance is defined by specified Zener voltage (VZ = 6.0 V), dynamic impedance (ZZ ≤ 1.0 Ω at IZT = 200 mA), and voltage regulation (ΔVZ = 0.19 V between 10% and 50% of IZM).
Thermal design relies on junction-to-lead thermal resistance of 25 °C/W at 3/8″ (10 mm) lead length, enabling 5 W dissipation with adequate heat sinking. It meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity and withstands 8.3 ms non-recurrent surge currents up to 12.7 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.0 V ±10% - defines precise clamping threshold for overvoltage protection and reference stability |
| Test Current (IZT) | 200 mA - operating point where VZ and ZZ are guaranteed per spec |
| Dynamic Impedance (ZZ) | ≤1.0 Ω - ensures minimal output voltage variation under load current changes |
| Max Regulator Current (IZM) | 790 mA - maximum continuous reverse current before thermal runaway at rated power |
| Power Dissipation (PD) | 5.0 W at TL < 25°C - requires mechanical heat sinking via leads for full-rated operation |
| Operating Temperature | –65°C to +150°C - supports industrial and automotive under-hood environments |
| Forward Voltage (VF) | ≤1.2 V @ 1.0 A - enables use as low-drop rectifier or clamp in forward bias |
Pinout & Package
Package: Axial-leaded T-18 plastic case (Void-free UL94V-0 epoxy), cathode indicated by color band. Leads are annealed matte-tin plated per MIL-STD-750 Method 2026, RoHS compliant (e3 suffix), weight 0.7 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Non-banded lead | Connected to lower-potential node; reverse-biased operation requires this terminal grounded or at lower voltage than cathode |
| Cathode | Banded lead | Connected to regulated output or protected node; Zener breakdown occurs when cathode is ≥6.0 V above anode |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC-registered Zener series | Ensures standardized electrical behavior and interchangeability across qualified suppliers |
| ±10% voltage tolerance (A suffix) | Cost-optimized regulation accuracy suitable for non-critical feedback and protection circuits |
| 5 W power rating with 25 °C/W θJL | Enables high-current regulation without external heatsink when leads are thermally anchored |
| Level 1 moisture sensitivity | Eliminates dry-pack requirement and bake-out prior to PCB assembly |
| Nonsensitive to ESD (MIL-STD-750 Method 1020) | Reduces handling precautions and eliminates need for ESD-safe workstations during assembly |
Applications
| Switching Power Supply Feedback | Overvoltage Protection Clamp |
|---|---|
Use Scenario: Regulates output voltage in flyback or forward converter feedback loop using optocoupler-coupled error amplifier. IC Role / Device Role / Timing Role: Provides stable 6.0 V reference to error amplifier input, enabling precise output setpoint control. Use Value: Maintains ±10% output regulation across line/load/temperature with 1.0 Ω ZZ minimizing feedback loop gain variation. | Use Scenario: Clamps transient surges on 5 V logic rail caused by inductive switching or ESD events. IC Role / Device Role / Timing Role: Acts as shunt protector, conducting excess energy to ground when rail exceeds 6.6 V (VZ + tolerance). Use Value: Absorbs 5 W continuously or 12.7 A surge (8.3 ms) without failure, protecting downstream 5 V ICs. |
| Reference Voltage Generator | DC-DC Converter Bias Supply |
Use Scenario: Generates stable 6.0 V bias for op-amp comparators or analog sensor interfaces in industrial controllers. IC Role / Device Role / Timing Role: Serves as passive precision reference source independent of input voltage fluctuations. Use Value: Delivers <0.19 V regulation error (ΔVZ) across 79–395 mA operating range, ensuring comparator trip-point stability. | Use Scenario: Powers gate driver ICs in half-bridge motor drivers where isolated auxiliary supply is unavailable. IC Role / Device Role / Timing Role: Provides regulated 6.0 V local supply derived from main DC bus, reducing dependency on LDOs. Use Value: Supports 790 mA max current, enabling direct drive of multiple gate drivers without additional regulation stages. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5340B | Same 6.0 V nominal VZ, but ±5% tolerance (B suffix) and 1.0 Ω ZZ at 200 mA | Higher accuracy required for tighter feedback loops or precision references | Select 1N5340B when ±5% regulation is needed; 1N5340AE3/TR13 remains optimal for cost-sensitive overvoltage clamping |
| MMBZ5234B | Surface-mount SOT-23 package, 6.2 V nominal, ±5%, 200 mW rating, ZZ = 17 Ω | Low-power, space-constrained designs where 5 W dissipation is unnecessary | Choose MMBZ5234B only for sub-200 mW applications; 1N5340AE3/TR13 is mandatory for >500 mA continuous current demands |
Compared with 1N5340B and MMBZ5234B, the 1N5340AE3/TR13 uniquely balances cost-effective ±10% tolerance, 5 W power handling, and axial-leaded through-hole mounting-making it the preferred choice for industrial power supplies requiring robust, serviceable, and thermally manageable regulation.

FAQ
What is the Zener voltage tolerance of the 1N5340AE3/TR13?
The 1N5340AE3/TR13 has a Zener voltage tolerance of ±10%, indicated by the "A" suffix in its part number. This means its actual breakdown voltage falls between 5.4 V and 6.6 V at 200 mA test current and 25°C. The e3 suffix confirms RoHS compliance, and TR13 denotes tape-and-reel packaging per EIA-296. This tolerance level is suited for general-purpose regulation where tight accuracy is not critical.
Can the 1N5340AE3/TR13 be used in surface-mount designs?
No-the 1N5340AE3/TR13 is an axial-leaded T-18 package and is not compatible with surface-mount assembly. For SMT equivalents, Microsemi offers the SMBJ5340B (6.0 V, ±5%, 5 W) in DO-214AA package. The 1N5340AE3/TR13 requires through-hole mounting with 3/8″ (10 mm) lead length from body for rated 5 W dissipation; improper lead trimming degrades thermal performance.
What is the maximum surge current rating for the 1N5340AE3/TR13?
The 1N5340AE3/TR13 has a maximum non-recurrent surge current (IZSM) of 12.7 A, specified for an 8.3 ms half-sine waveform. This rating reflects its ability to absorb transient energy without failure-critical for overvoltage protection in motor drives or power converters. Surge capability is validated per JEDEC standards and assumes proper PCB layout with adequate copper pour for thermal dissipation during the event.
How does thermal resistance affect the 1N5340AE3/TR13's power rating?
The 1N5340AE3/TR13 has a junction-to-lead thermal resistance (θJL) of 25 °C/W at 3/8″ lead length, enabling full 5 W dissipation only when leads are thermally anchored to large copper areas or heatsinks. On standard FR4 with 4 mm² pads, ambient-rated power drops to 1.47 W due to higher θJA (85 °C/W). Derating curves in the datasheet must be followed to avoid thermal runaway at elevated ambient temperatures.
Is the 1N5340AE3/TR13 suitable for automotive under-hood applications?
Yes-the 1N5340AE3/TR13 operates from –65°C to +150°C and meets MIL-PRF-19500 screening levels when ordered with MQ/MX/MV prefixes. Its UL94V-0 epoxy case, Level 1 moisture sensitivity, and nonsensitivity to ESD (per MIL-STD-750 Method 1020) support under-hood deployment. However, full automotive qualification (AEC-Q101) requires specific screening; standard 1N5340AE3/TR13 is rated for industrial-grade reliability unless explicitly ordered as JAN/JANTX.
