Product details
Overview
1N6270AHE3_A/C 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 9.1 V breakdown voltage (VBR = 8.65–9.55 V at IT = 1.0 mA), 7.78 V maximum working voltage (VWM), 13.4 V clamping voltage (VC) at 112 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces against lightning-induced surges and inductive switching transients in automotive and industrial control systems.
For engineers reviewing the 1N6270AHE3_A/C datasheet, 1N6270AHE3_A/C pinout, 1N6270AHE3_A/C application, or 1N6270AHE3_A/C equivalent, this part serves as a RoHS-compliant, AEC-Q101-qualified transient suppressor with verified bidirectional-capable family lineage (though 1N6270AHE3_A/C itself is unidirectional), low incremental surge resistance, and fast sub-nanosecond response - critical when selecting robust, high-reliability TVS devices for 12 V automotive subsystems, industrial PLC I/O protection, and telecom line interface circuits.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, optimized for unidirectional clamping in DC-biased circuits. Its 1500 W peak pulse power handling is defined per 10/1000 µs waveform at TA = 25 °C, with thermal derating above 25 °C per Fig. 2 and junction-to-lead thermal resistance of 15.4 °C/W enabling effective heat dissipation into PCB copper or leads.
The 1N6270AHE3_A/C exhibits a maximum reverse leakage of 50 µA at VWM = 7.78 V, clamps to ≤13.4 V at 112 A, and maintains stable breakdown with ±0.068 %/°C temperature coefficient - ensuring predictable protection behavior across -55 °C to +175 °C operating range without thermal runaway under repetitive surge conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 8.65 V / 9.55 V at IT = 1.0 mA - defines precise avalanche onset threshold for reliable triggering before downstream component damage |
| VWM | 7.78 V - maximum continuous DC or RMS voltage the device blocks without significant leakage, compatible with 5–9 V logic/power rails |
| VC @ IPPM | 13.4 V at 112 A - clamping voltage during 10/1000 µs surge, limiting stress on protected ICs to safe levels |
| PPPM | 1500 W - peak transient energy absorption capacity, sufficient for Level 4 IEC 61000-4-5 surge testing (4 kV/2 Ω) |
| IPPM | 112 A - maximum non-repetitive surge current the device sustains without failure, validated per JEDEC standards |
| TJ max. | +175 °C - extended junction temperature rating enables use in under-hood automotive and high-ambient industrial environments |
| Package | Case Style 1.5KE - axial-leaded DO-201AD package with 0.375" lead length, UL 94 V-0 molded epoxy body, matte tin-plated leads |
Pinout & Package
1N6270AHE3_A/C uses the standard DO-201AD (Case Style 1.5KE) axial-leaded package. The cathode is marked by a color band on the body; the anode is the unmarked end. Leads are matte tin-plated and solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | High-side connection to protected line | Connected to the rail or signal line requiring overvoltage clamping; conducts avalanche current to ground during transient |
| Anode (unmarked end) | Low-side reference node | Typically tied to system ground or common return path; completes clamping loop during surge event |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable, repeatable avalanche characteristics and long-term reliability under repeated surge stress |
| 1500 W peak pulse power (10/1000 µs) | Supports robust protection against high-energy transients including ISO 7637-2 Pulse 1/2/5a and IEC 61000-4-5 combination wave surges |
| AEC-Q101 qualified | Validated for automotive applications including engine control units, body electronics, and ADAS sensor interfaces |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes voltage overshoot during clamping, reducing risk of latch-up or gate oxide damage in protected MOSFETs and ICs |
| Sub-nanosecond response time | Clamps within <1 ns, faster than MOVs or polymer-based protectors - essential for safeguarding high-speed digital interfaces |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ9.0A | DO-214AA package (SMB), lower PPPM = 600 W, VBR = 10.0–11.1 V, VC = 15.4 V @ 39.0 A | Smaller footprint but reduced surge capacity; suitable for space-constrained consumer designs with lower threat levels | Select SMBJ9.0A only if board area is critical and surge requirements are ≤600 W; not drop-in due to different package and thermal profile |
| 1.5KE9.1A-E3/54 | Same 1.5KE package and electrical specs, but commercial-grade (non-AEC-Q101), E3 suffix only (no HE3 qualification) | Lacks automotive qualification; acceptable for industrial/commercial applications where AEC-Q101 is not mandated | Choose 1.5KE9.1A-E3/54 for cost-sensitive non-automotive use; 1N6270AHE3_A/C remains preferred where automotive reliability and traceability are required |
Compared with SMBJ9.0A, 1N6270AHE3_A/C delivers 2.5× higher surge power and superior thermal performance in axial-leaded mounting; versus 1.5KE9.1A-E3/54, it adds AEC-Q101 qualification, JESD 201 Class 2 whisker resistance, and enhanced process controls - making it the sole choice for automotive Tier-1 supply chain compliance.

FAQ
What is the breakdown voltage tolerance of the 1N6270AHE3_A/C?
The 1N6270AHE3_A/C has a specified breakdown voltage range of 8.65 V to 9.55 V at test current IT = 1.0 mA, representing a ±5.5 % tolerance about the nominal 9.1 V rating. This tight VBR distribution ensures consistent clamping behavior across production lots and supports reliable design margining in 9 V rail protection schemes.
Is the 1N6270AHE3_A/C suitable for bidirectional transient protection?
No - the 1N6270AHE3_A/C is a unidirectional TVS diode, intended for DC-biased applications where only positive-going transients require suppression. For bidirectional protection (e.g., AC lines or floating signals), Vishay offers variants with "CA" suffix such as 1.5KE9.1CA; the 1N6270AHE3_A/C must be used with correct polarity orientation to avoid forward conduction during normal operation.
What does the "HE3_A/C" suffix indicate in 1N6270AHE3_A/C?
The "HE3" denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "A/C" specifies the revision code per Vishay's internal change control - confirming compliance with the 09-Aug-2022 revision of document 88301. This distinguishes it from commercial-grade E3-only versions like 1.5KE9.1A-E3/54.
How does the 1N6270AHE3_A/C perform under elevated ambient temperatures?
The 1N6270AHE3_A/C follows standard derating per Fig. 2 in the datasheet: its 1500 W peak pulse power is fully rated at TA = 25 °C, decreasing linearly to ~750 W at TA = 100 °C and zero at TJ = 175 °C. Its RθJL = 15.4 °C/W allows effective heat transfer to PCB copper or chassis, supporting sustained operation in high-temperature enclosures when properly mounted.
Can the 1N6270AHE3_A/C replace older 1N6270A parts in existing designs?
Yes - the 1N6270AHE3_A/C is a direct functional and mechanical replacement for legacy 1N6270A, with identical electrical specifications, DO-201AD package dimensions, and pinout. It adds RoHS compliance, AEC-Q101 qualification, and enhanced process controls, making it suitable for both new designs and drop-in upgrades in automotive and industrial applications where reliability and compliance are critical.
