Product details
Overview
1N6292AHE3_B/C from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary-level overvoltage protection in power rails and signal lines. It features a 71.3 V to 78.8 V breakdown voltage (VBR), 64.1 V standoff voltage (VWM), 1500 W peak pulse power (10/1000 µs), 14.6 A peak pulse current (IPPM), and clamps to ≤104 V at rated surge - used in automotive power supply inputs and industrial sensor interface protection.
For engineers reviewing the 1N6292AHE3_B/C datasheet, 1N6292AHE3_B/C pinout, 1N6292AHE3_B/C application, or 1N6292AHE3_B/C equivalent, this part delivers AEC-Q101-qualified transient suppression with glass-passivated junction, low incremental surge resistance, and fast sub-nanosecond response - critical when safeguarding 24 V control circuits against ISO 7637-2 pulses or inductive switching transients.
Technical Context
This TVS diode operates as a unidirectional clamping device with a single P-N junction optimized for high-energy transient absorption. Its 10/1000 µs waveform rating reflects standardized surge immunity testing per IEC 61000-4-5, and its 175 °C maximum junction temperature supports under-hood automotive deployment.
The device uses a molded epoxy case (Case Style 1.5KE) with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102. The HE3 suffix denotes RoHS compliance and AEC-Q101 qualification; the "B/C" revision indicates tape-and-reel packaging per EIA-481-D standard with 1400 units per 13″ reel.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 71.3 V / 78.8 V - ensures reliable conduction onset above normal 64.1 V operating rail, preventing false triggering during load dump or ripple. |
| VWM | 64.1 V - maximum continuous reverse voltage before leakage exceeds 1 µA, compatible with 24 V nominal systems with ±20 % tolerance. |
| IPPM | 14.6 A - peak surge current it safely clamps at 104 V, sufficient to absorb 1500 W transients from inductive kickback in solenoid drivers. |
| PPPM | 1500 W - 10/1000 µs pulse power rating, enabling robust protection against lightning-induced surges per IEC 61000-4-5 Level 4. |
| TJ max. | 175 °C - extended thermal capability allows placement near heat sources in engine control units without derating loss. |
| RθJL | 15.4 °C/W - low junction-to-lead thermal resistance enables effective heat dissipation through PCB copper pours or chassis mounting. |
Pinout & Package
Package: Case Style 1.5KE - axial-leaded, molded epoxy body (0.375″ lead length), UL 94 V-0 rated, 0.968 g unit weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or return path; forms clamping loop with cathode during reverse-biased surge events. |
| Cathode | High-side surge input terminal | Connected to protected line (e.g., 24 V supply); color band identifies this end for correct polarity orientation. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR over lifetime and resistance to humidity-induced parameter drift in under-hood environments. |
| AEC-Q101 qualified | Validated for automotive applications including powertrain and body electronics per stress test requirements (HTOL, TCT, etc.). |
| 1500 W peak pulse power | Supports single-event surge handling up to 1500 W without degradation - meets ISO 7637-2 Pulse 5a (load dump) requirements. |
| Sub-nanosecond response time | Clamps transients within <1 ns, protecting downstream MOSFETs and microcontrollers before damage thresholds are exceeded. |
| Low clamping ratio (VC/VBR ≈ 1.33) | Minimizes let-through voltage during clamping - keeps protected ICs below absolute maximum ratings during 104 V clamp event. |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 24 V supply rails in engine control modules against load dump transients (ISO 7637-2 Pulse 5a). IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery feed and DC/DC converter input to clamp surges >64 V. Use Value: Limits peak voltage to ≤104 V, preventing overvoltage failure of input-stage MOSFETs and LDO regulators. |
Use Scenario: Shielding analog output lines (e.g., 4–20 mA current loops) from ESD and cable discharge events. IC Role / Device Role / Timing Role: TVS connected across signal and ground at connector entry point to shunt fast transients. Use Value: Sub-ns response prevents latch-up in op-amps and ADC front-ends during 8 kV contact ESD per IEC 61000-4-2. |
| Telecom DC Power Feeds | Consumer Appliance Motor Driver Protection |
Use Scenario: Safeguarding PoE-powered equipment DC inputs against induced surges on long outdoor cabling. IC Role / Device Role / Timing Role: Primary clamping device on 48 V DC input before secondary filtering and regulation. Use Value: 1500 W rating handles multi-kV lightning-induced surges per IEC 61000-4-5, preserving upstream rectifier bridges. |
Use Scenario: Suppressing back-EMF spikes from brushed DC motors in smart home appliances (e.g., washing machine pumps). IC Role / Device Role / Timing Role: Mounted across motor terminals to clamp inductive kickback during PWM commutation. Use Value: Clamps 100+ V spikes to ≤104 V, eliminating need for snubber RC networks and reducing board space. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75A-E3/52 | Lower PPPM (600 W), smaller SMB package (surface-mount), VBR = 83.3–92.1 V, VC = 121 V at 4.9 A. | Not AEC-Q101 qualified; suited for space-constrained consumer PCBs but lacks automotive thermal and reliability validation. | Select when board area is limited and surge energy is ≤600 W; avoid for under-hood or safety-critical automotive use. |
| 1.5KE75AHE3_A | Same electrical specs and 1.5KE package, but earlier revision (A vs. B/C); identical clamping and thermal performance. | No functional difference - same AEC-Q101 qualification, RoHS compliance, and mechanical dimensions. | Acceptable drop-in replacement if B/C revision stock is unavailable; verify revision-specific traceability requirements with OEM. |
Compared with SMBJ75A-E3/52, 1N6292AHE3_B/C provides 2.5× higher surge power and automotive qualification; compared with 1.5KE75AHE3_A, it offers updated manufacturing controls and enhanced whisker resistance (JESD 201 Class 2).

FAQ
What is the breakdown voltage range for the 1N6292AHE3_B/C?
The 1N6292AHE3_B/C has a specified breakdown voltage (VBR) range of 71.3 V minimum to 78.8 V maximum at 1.0 mA test current. This tight tolerance ensures consistent clamping behavior across production lots and supports reliable operation in 24 V systems subject to wide input variation and load dump conditions.
Is the 1N6292AHE3_B/C suitable for automotive applications?
Yes, the 1N6292AHE3_B/C is AEC-Q101 qualified and explicitly listed in Vishay's qualified parts list for 1.5KE6.8AHE3_B to 1.5KE220AHE3_B variants. Its 175 °C maximum junction temperature, glass-passivated junction, and validated HTOL/TCT performance make it appropriate for engine bay, body control, and powertrain modules.
What does the "HE3_B/C" suffix mean in 1N6292AHE3_B/C?
The "HE3" suffix indicates RoHS compliance and AEC-Q101 qualification; "B/C" denotes the revision level and packaging format - specifically, 13″ paper tape and reel with 1400 units per reel, conforming to EIA-481-D standards. The "B" revision supersedes "A", and "C" may indicate minor process or marking updates.
How does the 1N6292AHE3_B/C compare to bidirectional TVS diodes like 1N6292CAHE3_B/C?
The 1N6292AHE3_B/C is unidirectional and intended for DC line protection with defined polarity; 1N6292CAHE3_B/C is bidirectional and used in AC or floating signal paths. They share identical VBR, VC, and PPPM, but the unidirectional version offers lower forward voltage (3.5 V @ 100 A) and is not rated for symmetrical AC transients.
What is the maximum clamping voltage of the 1N6292AHE3_B/C at rated surge current?
The 1N6292AHE3_B/C clamps to a maximum of 104 V at its rated peak pulse current (IPPM) of 14.6 A under 10/1000 µs waveform conditions. This clamping voltage defines the upper limit of let-through energy to downstream components and is critical for ensuring protected ICs remain within their absolute maximum voltage ratings.
