Product details
Overview
1N5658A/TR from Microchip Technology is a unidirectional transient voltage suppressor (TVS) diode in a hermetically sealed DO-13 metal package, rated for 1500 W peak pulse power at 10/1000 µs, with 94.0 V standoff voltage (VWM), 105 V breakdown voltage (VBR min), and 152 V clamping voltage (VC) at 9.9 A peak pulse current. It is used for secondary lightning protection in avionics and industrial control systems with 12 Ω source impedance per IEC61000-4-5 Class 1.
For engineers reviewing the 1N5658A/TR datasheet, 1N5658A/TR pinout, 1N5658A/TR application, or 1N5658A/TR equivalent, this page delivers verified electrical parameters, military-grade qualification context (JANTXV-compatible), DO-13 mechanical interface details, and IEC-compliant surge class mapping - all specific to the 1N5658A/TR variant with TR tape-and-reel packaging.
Technical Context
This unidirectional TVS operates in avalanche breakdown during transients, clamping within <100 ps while maintaining a 94.0 V DC standoff level. Its hermetic DO-13 package ensures reliability in harsh environments including aerospace and military systems where moisture ingress and thermal cycling are concerns.
The device complies with MIL-PRF-19500/500 for JANTXV qualification when prefixed accordingly, supports 200 A forward surge current (8.3 ms half-sine), and exhibits a +0.107 %/°C temperature coefficient of VBR, enabling predictable voltage drift over temperature in precision protection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 94.0 V - Maximum continuous reverse operating voltage before conduction begins; sets system-level DC margin for protected line. |
| VBR (min) | 105 V @ 1 mA - Minimum breakdown threshold ensuring reliable turn-on above normal operating voltage. |
| VC @ IPP | 152 V @ 9.9 A - Clamped voltage during 10/1000 µs surge; defines worst-case stress on downstream circuitry. |
| PPP | 1500 W - Peak pulse power handling capability under standardized surge waveform; enables robust IEC61000-4-5 Class 1 compliance. |
| ID @ VWM | 5 µA - Leakage current at rated standoff; low enough to avoid loading sensitive analog or high-impedance signal paths. |
| Package | DO-13 (DO-202AA) - Hermetically sealed metal-glass case with cathode-to-case polarity; provides superior thermal dissipation and long-term stability vs. plastic packages. |
| αVBR | +0.107 %/°C - Temperature coefficient of breakdown voltage; allows accurate derating across -55°C to +175°C operating range. |
Pinout & Package
Hermetically sealed DO-13 (DO-202AA) metal-glass package with axial leads; cathode terminal connected directly to the metal case and marked by a diode symbol on the body. Lead length 1.000–1.625 inches; weight ≈1.4 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 2) | Transient current entry point | Connected to protected line; carries full surge current into the junction during clamping. |
| Cathode (Lead 1 / Case) | Reference and return path | Electrically tied to metal case; must be connected to system ground plane for effective ESD/lightning energy shunting. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power | Enables single-device protection against IEC61000-4-5 Class 1 surges (12 Ω source) without cascaded staging. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMCJ93A | Surface-mount SMC package; same 93 V VWM, but 1500 W rating at 10/1000 µs and 156 V VC @ 9.6 A. | Requires PCB re-layout due to SMD footprint; unsuitable for through-hole legacy designs or high-vibration mounting. | Select when board space is constrained and automated assembly is preferred over manual DO-13 insertion. |
| 1N5658A | Identical electrical specs and DO-13 package, but supplied in bulk (not tape-and-reel); no TR suffix. | No functional difference; only packaging format differs - TR enables automated pick-and-place, bulk supports hand-solder prototyping. | Choose 1N5658A/TR for production lines using reel-fed feeders; choose 1N5658A for low-volume builds or repair spares. |
Compared with SMCJ93A and 1N5658A, the 1N5658A/TR offers identical protection performance in a hermetic through-hole package optimized for high-reliability, vibration-prone, or legacy-compatible deployments - with TR packaging enabling scalable manufacturing without sacrificing ruggedness.

FAQ
What is the standoff voltage (VWM) of the 1N5658A/TR?
The 1N5658A/TR has a rated standoff voltage (VWM) of 94.0 V, meaning it remains non-conductive up to this reverse DC voltage level. This value is selected to provide a safety margin above typical 100 VDC system rails while ensuring reliable clamping onset during transients. The 1N5658A/TR maintains leakage current below 5 µA at this voltage, minimizing impact on upstream power sources.
Does the 1N5658A/TR meet IEC61000-4-5 Class 1 requirements?
Yes, the 1N5658A/TR is validated for IEC61000-4-5 Class 1 secondary lightning protection with a 12 Ω source impedance. Its 152 V clamping voltage at 9.9 A peak pulse current ensures protected circuits remain within safe operating limits during standardized 1.2/50 µs open-circuit voltage and 8/20 µs short-circuit current waveforms. The 1N5658A/TR achieves this without external components or derating.
What is the package type and mounting style of the 1N5658A/TR?
The 1N5658A/TR uses a DO-13 (DO-202AA) hermetically sealed metal-glass package with axial leads, designed for through-hole mounting. The cathode is electrically connected to the metal case and marked by a diode symbol on the body. Its 1.4 g mass and thermal resistance of 50°C/W (junction-to-lead) support robust heat dissipation in high-power transient events.
How does the "TR" suffix affect the 1N5658A/TR compared to 1N5658A?
"TR" denotes tape-and-reel packaging per EIA-296 standard, enabling automated surface-mount or through-hole placement in high-volume production. Electrically and mechanically, the 1N5658A/TR is identical to the bulk-packaged 1N5658A - same DO-13 case, same 94.0 V VWM, same 152 V VC. The 1N5658A/TR simplifies logistics for SMT lines while retaining full compatibility with manual soldering or wave processes.
Is the 1N5658A/TR suitable for ESD protection per IEC61000-4-2?
Yes, the 1N5658A/TR clamps transients in less than 100 picoseconds, making it effective for IEC61000-4-2 ESD protection. Its low leakage (5 µA at 94.0 V) and precise 105 V breakdown threshold ensure rapid turn-on before ESD pulses damage sensitive inputs. The 1N5658A/TR is deployed in avionics and industrial interfaces where sub-nanosecond response is required to protect CMOS logic and ADC front-ends.
