Product details
Overview
1N6300A-E3/54 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 152 V to 168 V breakdown voltage range (VBR), 136 V maximum standoff voltage (VWM), 219 V clamping voltage at 6.8 A peak pulse current, 1500 W peak pulse power rating (10/1000 µs), and operates across –55 °C to +175 °C junction temperature. It is used to protect MOSFETs, ICs, and sensor interfaces against lightning-induced surges and inductive switching transients.
For engineers reviewing the 1N6300A-E3/54 datasheet, 1N6300A-E3/54 pinout, 1N6300A-E3/54 application, or 1N6300A-E3/54 equivalent, this device serves as a high-energy, fast-response (sub-nanosecond) unidirectional TVS for industrial power supplies, automotive body electronics, and telecom interface protection where robust 1.5 kW surge handling and low clamping ratio are required.
Technical Context
The 1N6300A-E3/54 uses a glass-passivated silicon junction optimized for low incremental surge resistance and stable clamping under repetitive 10/1000 µs transients. Its unidirectional polarity enables cathode-referenced placement on positive-rail protection paths, with a color band marking the cathode terminal.
It delivers 219 V clamping voltage at 6.8 A IPPM, yielding a clamping ratio (VC/VBR) of ~1.37–1.44, and exhibits a temperature coefficient of VBR of +0.108 %/°C - critical for thermal stability in high-ambient environments like engine compartments or enclosed industrial enclosures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 152 V / 168 V - defines minimum guaranteed conduction threshold and maximum variation across production lot at 1 mA test current |
| VWM | 136 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA; sets safe DC bias margin |
| VC @ IPPM | 219 V at 6.8 A - peak clamped voltage during 10/1000 µs surge; determines protected circuit's maximum transient stress |
| PPPM | 1500 W - peak pulse power handling capability; supports single-event lightning surges per IEC 61000-4-5 Level 4 |
| IFSM | 200 A - non-repetitive forward surge current rating (8.3 ms half-sine); validates robustness against accidental polarity reversal |
| TJ max. | +175 °C - maximum junction temperature; enables use in under-hood automotive or high-power industrial environments |
| RθJA | 75 °C/W - thermal resistance junction-to-ambient; informs heatsinking requirements for sustained power dissipation |
Pinout & Package
1N6300A-E3/54 is housed in the industry-standard Case Style 1.5KE molded epoxy package (DO-201AD), featuring axial leads with matte tin plating. The cathode is marked by a color band on the body end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or return path in unidirectional clamp configuration; carries full surge current during clamping |
| Cathode | High-side connection point | Connected to protected line (e.g., +12 V rail); color band identifies this terminal; reverse-biased during normal operation |
Key Features

Applications
| Automotive Body Control Module (BCM) Power Input | Industrial PLC Digital I/O Protection |
|---|---|
Use Scenario: Protecting 12 V supply input of BCM against load dump (ISO 7637-2 Pulse 5a) and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and upstream fuse; clamps >100 V spikes within <1 ns. Use Value: Limits voltage seen by PMIC and microcontroller to ≤219 V, preventing latch-up or gate oxide damage during 120 V/500 ms load dump events. |
Use Scenario: Safeguarding 24 V digital input channels of programmable logic controllers against field-wiring induced surges. IC Role / Device Role / Timing Role: Primary protection device mounted at connector entry point; shunts inductive kickback from solenoid/relay coils. Use Value: Clamps 400 V transients to 219 V at 6.8 A, enabling downstream optocoupler and Schmitt trigger ICs to remain functional without reset or damage. |
| Telecom Line Interface Surge Protection | DC Motor Drive Power Stage Protection |
Use Scenario: Shielding RS-485 transceiver power pins from lightning-induced surges on long outdoor cable runs. IC Role / Device Role / Timing Role: Secondary-level TVS on VCC rail feeding isolated transceiver; complements gas discharge tube (GDT) front-end. Use Value: Provides low-clamp backup protection after GDT fires, ensuring VCC stays below 219 V to prevent transceiver latch-up or internal regulator failure. |
Use Scenario: Suppressing flyback voltage spikes generated by brushed DC motor commutation in robotic actuator drives. IC Role / Device Role / Timing Role: Unidirectional clamp across H-bridge high-side MOSFET drain-source; absorbs inductive energy during PWM turn-off. Use Value: Limits VDS overshoot to 219 V, reducing stress on 200 V-rated MOSFETs and eliminating need for larger, costlier devices. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A | Lower PPPM (600 W), smaller SMB package (vs. DO-201AD), VC = 259 V @ 2.3 A | Not suitable for IEC 61000-4-5 Level 4; limited to lower-energy surges in space-constrained designs | Select when board area is critical and surge threat level is ≤Level 3; verify thermal derating for continuous operation. |
| 1.5KE160A | Same electrical specs and package; identical performance; differs only in part numbering convention (JEDEC vs. manufacturer prefix) | No functional difference; both meet same Vishay specification 88301 and share identical qualification data | Direct form-fit-function replacement; interchangeability confirmed in Vishay documentation and distributor cross-reference tables. |
Compared with 1N6300A-E3/54, SMBJ160A offers footprint savings but sacrifices 60 % peak power handling and higher clamping voltage, while 1.5KE160A provides identical protection performance in the same package with no design change required.

FAQ
What is the breakdown voltage tolerance for 1N6300A-E3/54?
The 1N6300A-E3/54 has a specified breakdown voltage (VBR) range of 152 V to 168 V at 1 mA test current, representing a ±5 % tolerance about the nominal 160 V rating. This tight tolerance ensures consistent clamping behavior across production lots and simplifies system-level surge margin calculations without requiring additional derating headroom.
Is 1N6300A-E3/54 suitable for automotive applications?
Yes - the 1N6300A-E3/54 is RoHS-compliant and offered in an AEC-Q101-qualified variant (1N6300AHE3_B). While the E3/54 suffix denotes commercial-grade qualification, its 175 °C max junction temperature, glass-passivated junction, and 200 A IFSM rating make it suitable for under-dash and body-control applications where full AEC-Q101 validation is not mandated.
How does the clamping voltage of 1N6300A-E3/54 compare to its breakdown voltage?
The 1N6300A-E3/54 clamps to 219 V at its rated 6.8 A peak pulse current, resulting in a clamping ratio (VC/VBR) of approximately 1.37–1.44. This ratio reflects low incremental surge resistance and efficient energy absorption - critical for protecting 200 V-rated MOSFETs or 250 V capacitors without overdesigning downstream components.
What is the thermal resistance of 1N6300A-E3/54, and how does it affect layout?
The 1N6300A-E3/54 has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W. In PCB layouts, this requires ≥10 mm² of copper pour connected to each lead (especially cathode) to maintain safe junction temperatures during repetitive surges or elevated ambient conditions above 85 °C.
Can 1N6300A-E3/54 be used in bidirectional configurations?
No - 1N6300A-E3/54 is strictly unidirectional, as indicated by the "A" suffix and presence of a cathode band. Bidirectional variants (e.g., 1N6300CA) exist in the same family but are distinct orderable parts. Using 1N6300A-E3/54 in reverse-biased mode beyond VWM risks permanent breakdown due to lack of symmetrical clamping capability.
