Product details

Overview

1.5KE8.2AHR0G from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with 8.2V nominal breakdown voltage, 7.79–8.61V V_BR @ 10mA, 7.02V working stand-off voltage, and 130V clamping voltage at 200A peak impulse current. It protects automotive power rails and industrial I/O interfaces against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.

For engineers reviewing the 1.5KE8.2AHR0G datasheet, 1.5KE8.2AHR0G pinout, 1.5KE8.2AHR0G application, or 1.5KE8.2AHR0G equivalent, key selection criteria include clamping voltage under 200A surge, unidirectional polarity marking, DO-201 thermal derating above 25°C, and AEC-Q101 qualification status confirmed by "H" suffix.

Technical Context

This unidirectional TVS diode operates as a voltage-clamped shunt protector: it remains high-impedance below V_WM = 7.02V, then avalanches sharply at V_BR = 7.79–8.61V to clamp transients up to 1500W (10/1000μs). Its junction temperature range spans −55°C to +175°C, supporting under-hood automotive deployment.

Clamping performance is defined at 200A peak impulse current (I_PP), delivering V_C = 130V maximum - critical for safeguarding 12V system ICs with 135V absolute maximum ratings. The device exhibits <1μA leakage above 10V and 0.065%/°C V_BR temperature coefficient.

Key Specifications

Parameter	Value and Actual Design Meaning
V_BR @ I_T = 10mA	7.79–8.61V - defines precise avalanche onset threshold for reliable overvoltage triggering
V_WM	7.02V - maximum continuous DC or RMS voltage before leakage exceeds 1μA; sets safe operating margin below V_BR
V_C @ I_PP = 200A	130V max - peak clamped voltage during worst-case 10/1000μs surge; determines protected IC's voltage stress
P_PK	1500W - single-pulse surge power rating per JEDEC standard; enables robust protection against load dump and inductive kick
Junction Temp Range	−55°C to +175°C - supports operation in engine control units, battery management, and industrial motor drives
AEC-Q101 Qualified	Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per AEC specification
Package	DO-201 - industry-standard axial leaded package with 0.090g mass, UL 94V-0 molding, and tin-plated leads

Pinout & Package

DO-201 package: axial-leaded, cylindrical epoxy body with cathode band marking for unidirectional polarity. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Low-side reference node	Connected to ground or low-impedance return path; completes clamping loop during transient
Cathode	Protected line input	Connected to 12V rail or signal line; avalanche conduction occurs from cathode to anode when V_IN > V_BR

Key Features

Feature	Design Value
1500W 10/1000μs surge rating	Withstands automotive load dump and inductive switching events without degradation
130V clamping at 200A	Keeps downstream 12V-system ICs (e.g., CAN transceivers, MCU I/O) within safe voltage limits
AEC-Q101 qualified	Validated for automotive electronics use with extended temperature, humidity, and lifetime testing
0.065%/°C V_BR tempco	Ensures stable clamping threshold across −40°C to +125°C ambient operating range
DO-201 mechanical robustness	UL 94V-0 flammability rating and JESD 201 Class 2 whisker resistance support long-term reliability

Equivalent & Alternatives

The following parts are listed as comparable options for similar transient suppression applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Littelfuse SMAJ8.0A	Same DO-214AC package; lower P_PK = 400W; V_BR = 8.89–9.82V; V_C = 13.6V @ 26.5A	Lower surge capacity suits consumer electronics, not automotive load dump	Select only for cost-sensitive non-automotive designs where 200A surge immunity is unnecessary
ON Semiconductor 1.5KE8.2A	Same DO-201 package and electrical specs; lacks AEC-Q101 qualification and "H" suffix; no ISO 7637-2 validation	Acceptable for industrial controls but not automotive OEM or Tier-1 applications requiring AEC compliance	Use only if AEC-Q101 certification and ISO 7637-2 test reports are not required

Compared with Littelfuse SMAJ8.0A and ON Semi 1.5KE8.2A, the 1.5KE8.2AHR0G uniquely delivers automotive-grade 1500W surge handling with certified AEC-Q101 reliability and ISO 7637-2 immunity - essential for safety-critical 12V power rail protection where failure modes must be rigorously controlled.

FAQ

What does the "H" suffix in 1.5KE8.2AHR0G signify?

The "H" suffix in 1.5KE8.2AHR0G indicates full AEC-Q101 qualification - verified through temperature cycling, highly accelerated life testing (HALT), and ESD robustness tests per automotive reliability standards. This distinguishes it from non-H variants like 1.5KE8.2A, which lack formal automotive qualification. The 1.5KE8.2AHR0G is intended for use in engine control, body electronics, and ADAS modules where component-level automotive certification is mandatory.

What is the maximum clamping voltage of 1.5KE8.2AHR0G under surge conditions?

The 1.5KE8.2AHR0G has a maximum clamping voltage (V_C) of 130V at 200A peak impulse current (I_PP) using the standard 10/1000μs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. The 1.5KE8.2AHR0G maintains this clamping performance across its full operating temperature range of −55°C to +175°C.

Is 1.5KE8.2AHR0G unidirectional or bidirectional?

The 1.5KE8.2AHR0G is a unidirectional TVS diode, indicated by the absence of "CA" suffix and presence of cathode band marking on the DO-201 package. It conducts only when cathode voltage exceeds anode voltage by ≥V_BR, making it suitable for DC power rail protection. Bidirectional variants (e.g., 1.5KE8.2CA) are used for AC or data-line protection where polarity reversal occurs.

How does the 1.5KE8.2AHR0G compare to standard Zener diodes in surge protection?

Unlike general-purpose Zener diodes, the 1.5KE8.2AHR0G is engineered for high-power transient suppression: it handles 1500W single-pulse surges (vs. <1W for typical Zeners), achieves sub-nanosecond response, and maintains stable V_BR under high di/dt. Its DO-201 package provides superior thermal mass and surge current capability - critical for automotive load dump events where the 1.5KE8.2AHR0G sustains performance without parametric shift or failure.

What packaging options are available for 1.5KE8.2AHR0G?

The 1.5KE8.2AHR0G is supplied in DO-201 package with two standard packing formats: 1,250 pieces per tape-and-reel (1.5KE8.2AHR0G) and 500 pieces per ammo box (1.5KE8.2AHR0G). Both options feature green compound molding, date code (YWW), and factory marking per TSC's DO-201 outline drawing. Lead finish is pure tin, compliant with J-STD-002 solderability requirements.
