Product details
Overview
1.5KE8.2A B0G from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 8.2V, minimum VBR 7.79V at 10mA, maximum clamping voltage 13.0V at 200A peak pulse current, and working stand-off voltage 7.02V - designed for automotive ECU power rail protection against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE8.2A B0G datasheet, 1.5KE8.2A B0G pinout, 1.5KE8.2A B0G application, or 1.5KE8.2A B0G equivalent, key selection criteria include unidirectional polarity, 13.0V clamping performance at 200A, <1μA leakage above 10V, AEC-Q101 qualification option (H suffix), and DO-201 mechanical compatibility with high-surge industrial PCB layouts.
Technical Context
This unidirectional TVS diode operates as a shunt-clamping device that remains non-conductive below its 7.02V working stand-off voltage and rapidly avalanches to clamp transients up to 13.0V at 200A (10/1000μs waveform). Its low dynamic impedance ensures minimal voltage overshoot during fast-rising ESD or load-dump events.
Designed for automotive-grade reliability, it meets ISO 7637-2 immunity requirements and supports junction temperatures from −55°C to +175°C. The DO-201 package enables surface-mount or through-hole mounting with pure tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A | DO-214AA package; 8.0V nominal VBR; 13.6V clamping at 100A; 600W rating | Lower power rating and smaller footprint; suited for space-constrained consumer boards, not automotive load dump | Select when board area is critical and surge energy is ≤600W; verify thermal pad layout for SMB package |
| 1N6267A | Same DO-201 package; identical 8.2V nominal rating but tighter VBR min/max (6.45–7.14V); 10.5V clamping at 1000A | Higher test current (10mA vs. 1mA for 1.5KE8.2A); optimized for lower-voltage precision clamping | Choose for legacy designs using JEDEC 1N6267A footprint; note reduced surge current rating (1000A vs. 200A) |
Compared with SMBJ8.0A, 1.5KE8.2A B0G delivers 2.5× higher surge power and automotive-grade thermal margin; versus 1N6267A, it offers superior clamping consistency at high current and broader VBR tolerance for cost-sensitive production.

FAQ
What is the clamping voltage of the 1.5KE8.2A B0G under full-rated surge current?
The 1.5KE8.2A B0G clamps to a maximum of 13.0 V when subjected to its rated 200 A peak pulse current (10/1000 μs waveform). This value is measured per JEDEC standards and guarantees protection of downstream 12V logic ICs without exceeding their absolute maximum ratings. The 13.0 V clamping voltage is confirmed in the Electrical Specifications table on page 2 of the Taiwan Semiconductor 1.5KE Series datasheet (O2104).
Is the 1.5KE8.2A B0G unidirectional or bidirectional?
The 1.5KE8.2A B0G is a unidirectional TVS diode, indicated by the absence of "C" or "CA" suffix and confirmed by its single cathode band marking and asymmetric electrical parameters (e.g., forward voltage spec only applies to unidirectional types). It protects against positive transients on a line referenced to ground and must be installed with cathode toward the protected line. Bidirectional variants like 1.5KE8.2CA are explicitly marked and have symmetrical breakdown characteristics.
Does the 1.5KE8.2A B0G meet AEC-Q101 qualification?
The base 1.5KE8.2A B0G part is not AEC-Q101 qualified; however, the AEC-Q101 variant is designated as 1.5KE8.2AH (with "H" suffix) per Taiwan Semiconductor's Ordering Information table. The "B0G" suffix denotes green compound and tape-and-reel packaging, not qualification level. For automotive production, specify 1.5KE8.2AH B0G to ensure full AEC-Q101 compliance including stress testing for temperature cycling, HTRB, and ESD.
What is the maximum leakage current of the 1.5KE8.2A B0G at its working voltage?
At its working stand-off voltage of 7.02 V, the 1.5KE8.2A B0G exhibits a maximum blocking leakage current of less than 1 μA, as specified in the Electrical Specifications table. This ultra-low leakage preserves battery standby current in always-on automotive modules and avoids false triggering in high-impedance sensor interfaces. The value is verified at TA = 25°C and remains well below 5 μA even at +85°C per derating curves.
Can the 1.5KE8.2A B0G be used in a 24V automotive system?
Yes, the 1.5KE8.2A B0G is routinely deployed in 24V automotive systems - not as a primary rail protector (where higher VWM devices like 1.5KE27A are preferred), but for protecting low-voltage subcircuits such as 5V/3.3V regulator outputs, LIN bus lines, or sensor interfaces fed from the 24V main rail. Its 7.02V VWM provides adequate margin above 5V logic rails while delivering fast, low-clamp protection against coupled transients.
