Product details
Overview
P6KE8.2H from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-side overvoltage clamping in DC power rails and signal lines. It features a nominal breakdown voltage of 8.2V, maximum clamping voltage of 12.5V at 200A peak surge current, and stand-off voltage of 6.63V - enabling reliable protection of 5V–7V logic interfaces and automotive microcontroller I/O against ESD and inductive switching transients.
For engineers reviewing the P6KE8.2H datasheet, P6KE8.2H pinout, P6KE8.2H application, or P6KE8.2H equivalent, key selection criteria include its AEC-Q101 qualification, DO-15 package compatibility with high-density PCB layouts, low dynamic impedance (<0.065%/°C VBR tempco), and verified 10/1000μs surge capability - critical for automotive body control modules, industrial sensor front-ends, and LED driver input stages.
Technical Context
The P6KE8.2H operates as a silicon avalanche diode with unidirectional polarity and single-die construction in a DO-204AC (DO-15) package. Its junction exhibits fast response time (<1.0ps from 0V to VBR) and low leakage (<1μA at 7.02V), supporting robust immunity against electrical fast transients (EFT) per IEC 61000-4-4.
Clamping performance is defined by a maximum VC of 12.5V at IPP = 200A under 10/1000μs waveform, with thermal derating above 25°C per Fig.2 and junction temperature limits from −55°C to +175°C - ensuring stable operation in under-hood automotive environments and industrial power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Voltage | 8.2V - defines rated clamping threshold for 5V–7V system rail protection |
| Breakdown Voltage (VBR) | 7.38–9.02V at 10mA - ensures consistent avalanche initiation across production lots |
| Stand-Off Voltage (VWM) | 6.63V - allows safe continuous operation on 5V systems with 20% margin |
| Peak Pulse Power (PPK) | 600W at 10/1000μs - sustains automotive load dump and ISO 7637-2 pulse 1/2/5a events |
| Maximum Clamping Voltage (VC) | 12.5V at 200A - limits downstream IC stress below absolute maximum ratings of 13.2V-tolerant inputs |
| Junction Temperature Range | −55°C to +175°C - supports under-hood placement in AEC-Q101-compliant automotive designs |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with 0.400g mass and UL 94V-0 molding |
Pinout & Package
DO-204AC (DO-15) package with axial leads: cathode indicated by band marking; anode and cathode terminals are non-polarized in layout but functionally asymmetric for unidirectional clamping.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current sink during reverse-biased clamping | Connected to protected line; conducts surge current to ground when VLINE > VBR |
| Cathode (banded end) | Reference terminal / ground return path | Must be tied to low-impedance system ground to maintain clamping integrity and minimize ground bounce |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements including temperature cycling, HTRB, and ESD HBM ≥8kV |
| Low dynamic impedance | Enables tight clamping window (VC − VBR = ~5.1V) to protect sensitive 3.3V/5V logic without over-clamping |
| Fast response time | <1.0ps rise to VBR ensures suppression of sub-nanosecond ESD events before IC damage occurs |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for green manufacturing and end-of-life handling |
| UL recognition | File #E-326243 confirms flammability rating and safety compliance for use in certified end equipment |
Applications
| Automotive Body Control Module (BCM) | Industrial Sensor Signal Conditioning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A | Lower PPK (400W), SMA package (surface-mount), VBR min 7.22V, VC = 12.5V @ 32.4A | Designed for space-constrained PCBs; lower surge rating limits use in high-energy automotive pulses | Select for compact consumer electronics where 400W surge margin suffices and reflow assembly is required |
| 1.5KE8.2C | Same DO-15 package, bidirectional configuration, VBR 7.38–9.02V, VC = 13.4V @ 112A | Supports AC-coupled or floating signal lines; higher clamping voltage reduces protection margin for 5V logic | Choose for RS-485 or CAN bus termination where symmetrical surge protection is mandatory |
Compared with SMAJ8.0A and 1.5KE8.2C, the P6KE8.2H delivers higher 600W surge capacity in the same axial package and tighter clamping (12.5V vs. 13.4V) for unidirectional DC rails - making it optimal for automotive 12V systems requiring AEC-Q101 validation and legacy through-hole assembly.

FAQ
What is the AEC-Q101 qualification status of the P6KE8.2H?
The P6KE8.2H is explicitly AEC-Q101 qualified per the manufacturer's ordering code definition ("H" suffix denotes AEC-Q101 qualification for P6KE6.8 through P6KE440, excluding P6KE6V8A–P6KE9V1A). This includes full stress testing per AEC-Q101 Rev D, covering HTGB, HTRB, TCT, and ESD HBM ≥8kV - confirming suitability for automotive under-hood and chassis applications.
How does the P6KE8.2H differ from the P6KE8.2A variant?
The P6KE8.2H shares identical electrical specifications with P6KE8.2A - including VBR (7.79–8.61V), VWM (7.02V), VC (12.1V), and IPP (200A) - but adds AEC-Q101 qualification and uses the same DO-15 package. The "H" suffix indicates automotive-grade screening and traceability, while "A" denotes tighter VBR tolerance (±5%) without automotive qualification.
Can the P6KE8.2H be used in bidirectional signal protection?
No - the P6KE8.2H is unidirectional only, with cathode band marking and specified parameters (VBR, VC, IPP) valid only for reverse-bias operation. For bidirectional protection, select P6KE8.2CA or 1.5KE8.2C, which provide symmetrical clamping in both polarities and are tested accordingly per ANSI/IEEE C62.35.
What is the maximum allowable mounting temperature for soldering the P6KE8.2H?
The P6KE8.2H features pure tin-plated leads compliant with J-STD-002 for solderability. Peak solder temperature must not exceed 260°C for ≤10 seconds during wave or hand soldering; reflow profiles must follow IPC/JEDEC J-STD-020 guidelines for DO-15 packages to avoid internal delamination or bond wire damage.
Does the P6KE8.2H meet UL 94V-0 flammability requirements?
Yes - the P6KE8.2H uses molding compound certified to UL 94V-0 flammability rating, as confirmed in the Mechanical Data section. This enables use in end equipment requiring UL/CSA safety certification, including industrial controls and automotive infotainment systems where flame propagation resistance is mandated.
