Product details
Overview
1N753AE3/TR from Microsemi is a 500 mW, 6.2 V ±5% Zener diode in DO-35 glass axial package, qualified to JANTX level per MIL-PRF-19500/127, with 3 Ω dynamic impedance at 20 mA and +0.045 %/°C temperature coefficient - used for precision voltage reference and overvoltage protection in military power supplies.
For engineers reviewing the 1N753AE3/TR datasheet, 1N753AE3/TR pinout, 1N753AE3/TR application, or 1N753AE3/TR equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (250 °C/W junction-to-lead), reverse leakage (≤5 µA at 3.5 V), RoHS compliance (e3 suffix), and MIL-qualified reliability for high-reliability analog circuits.
Technical Context
This device operates as a two-terminal voltage regulator in reverse-biased breakdown mode, delivering stable 6.2 V regulation across 1 mA to 50 mA current range with minimal capacitance and inherent radiation hardness per MicroNote 050. Its metallurgically bonded junction ensures long-term stability under thermal cycling.
Designed for fixed-voltage reference and clamping, it supports operation from –65 °C to +175 °C, with linear power derating from 500 mW at 50 °C lead temperature to zero at 175 °C - requiring no external biasing circuitry beyond series current limiting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 6.2 V ±5% at IZT = 20 mA - defines nominal regulation point with tight production control for repeatable reference accuracy |
| Dynamic Impedance ZZT | 3 Ω at IZT = 20 mA - ensures low output impedance for stable regulation under varying load currents |
| Max Reverse Leakage IR | ≤5 µA at VR = 3.5 V - guarantees minimal standby power loss in high-impedance bias networks |
| Temp Coefficient αVZ | +0.045 %/°C - enables predictable voltage drift compensation in wide-temperature military systems |
| Power Dissipation PM(AV) | 500 mW at TL = 50 °C - sets maximum continuous DC power handling before thermal derating begins |
| Junction-to-Lead RθJL | 250 °C/W - determines thermal rise above lead temperature during steady-state operation |
| Forward Voltage VF | 1.1 V at IF = 200 mA - defines conduction threshold when used in forward-biased protection paths |
Pinout & Package
DO-35 (DO-204AH) hermetically sealed glass axial package with tin-lead or RoHS-compliant matte-tin plating; cathode indicated by band - banded end must be held positive relative to anode for Zener regulation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current sink in reverse bias | Connected to lower-potential node; carries full Zener current during regulation |
| Cathode (banded end) | Regulated output node | Held at stable 6.2 V above anode; serves as reference or clamp point |
Key Features
| Feature | Design Value |
|---|---|
| JANTX qualification per MIL-PRF-19500/127 | Validated reliability for aerospace and defense programs requiring screened lots and traceable test data |
| Internal metallurgical bond | Eliminates wire-bond fatigue failure modes, enabling >100,000 thermal cycles without parameter shift |
| RoHS-compliant e3 marking | Meets EU Directive 2011/65/EU for commercial-grade versions without lead exemption waivers |
| Non-sensitive to ESD (MIL-STD-750 Method 1020) | Withstands ≥4 kV HBM without degradation - simplifies handling in uncontrolled assembly environments |
| Inherent radiation hardness | Functional up to 100 krad(Si) total ionizing dose per Microsemi MicroNote 050 - suitable for space-qualified subsystems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N753A-1 | Same 6.2 V, ±5%, DO-35 package but non-RoHS (no e3 suffix); JANTX qualified | Identical electrical performance; lacks RoHS compliance required for new commercial designs | Select when legacy MIL-spec compliance without RoHS is mandated |
| BZX55C6V2 | 6.2 V ±5%, DO-35, commercial grade only; 5 Ω ZZT, higher leakage (≤10 µA), no MIL qualification | Lower cost for industrial prototypes; unsuitable for flight hardware or screened procurement | Select for cost-sensitive ground-based equipment where MIL screening is unnecessary |
Compared with 1N753A-1 and BZX55C6V2, the 1N753AE3/TR uniquely combines JANTX-level screening, RoHS compliance, and 3 Ω dynamic impedance - making it the only option meeting both military reliability and modern environmental requirements in a single part.

FAQ
What is the Zener voltage tolerance for 1N753AE3/TR?
The 1N753AE3/TR has a nominal Zener voltage of 6.2 V with a ±5% tolerance, meaning the actual regulation voltage falls between 5.89 V and 6.51 V at 20 mA test current. This tolerance is confirmed in the Electrical Characteristics table on page 3 of Microsemi's T4-LDS-0288 datasheet. The "A" in the part number explicitly denotes the 5% tolerance grade for the 1N753AE3/TR.
Is 1N753AE3/TR RoHS compliant?
Yes, the "e3" suffix in 1N753AE3/TR indicates RoHS compliance per EU Directive 2011/65/EU, with annealed matte-tin plating. Per the Mechanical and Packaging section (page 2), RoHS compliance applies only to commercial-grade versions - and the TR tape-and-reel packaging confirms this is a commercial variant. The 1N753AE3/TR meets all six restricted substance limits without exemptions.
What is the maximum power dissipation for 1N753AE3/TR at 75°C ambient?
At 75°C ambient on a standard FR4 PCB with 1 oz copper, the 1N753AE3/TR derates to approximately 400 mW - based on the Figure 2 derating curve in the datasheet. Its rated 500 mW applies only at 50°C lead temperature; above that, power linearly decreases to zero at 175°C. For PCB-mounted use, the 1N753AE3/TR delivers 400 mW at 55°C ambient, dropping to ~300 mW at 75°C.
Does 1N753AE3/TR have MIL-PRF-19500/127 qualification?
No - the 1N753AE3/TR is a RoHS-compliant commercial-grade version and carries no MIL qualification. Per the nomenclature table (page 2), the blank reliability level field (no JAN/JANTX/JANTXV prefix) and "e3" suffix confirm commercial status. Only variants like 1N753A-1 (no e3) or JANTX1N753A-1 meet MIL-PRF-19500/127. The 1N753AE3/TR retains the same electrical specs but lacks screened lots and military test documentation.
What is the cathode identification method for 1N753AE3/TR?
The cathode of the 1N753AE3/TR is identified by a visible color band on the glass DO-35 body - the banded end must be held at higher potential than the anode for proper Zener regulation. This polarity marking is specified in the Mechanical and Packaging section (page 2) and aligns with JEDEC standard diode orientation. Reversing polarity subjects the 1N753AE3/TR to forward conduction (1.1 V drop), not regulation.
