Product details
Overview
P6SMB100CH from Taiwan Semiconductor is a bidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a 90–110 V breakdown voltage, 81.0 V stand-off voltage, and 144 V clamping voltage at 4.3 A peak pulse current. It features glass-passivated junction, AEC-Q101 qualification, and ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance for automotive load-dump and EFT protection.
For engineers reviewing the P6SMB100CH datasheet, P6SMB100CH pinout, P6SMB100CH application, or P6SMB100CH equivalent, key selection criteria include unidirectional vs. bidirectional configuration (CH = bidirectional), clamping performance under 10/1000 µs transients, thermal resistance (RθJA = 55 °C/W), and moisture sensitivity level (MSL 1).
Technical Context
The P6SMB100CH operates as a bidirectional avalanche diode, symmetrically clamping voltage transients in both polarities. Its glass-passivated junction ensures stable VBR tolerance (±10% min/max), low leakage (<1 µA @ 81.0 V), and fast response (<1.0 ps rise time from 0 V to VBR min).
Designed for automotive-grade reliability, it meets AEC-Q101 stress tests and supports ISO 7637-2 immunity requirements across all five pulse waveforms. Thermal performance is defined by RθJC = 10 °C/W and RθJA = 55 °C/W, enabling operation up to TJ = +150 °C in DO-214AA (SMB) package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 90 V / 110 V - defines guaranteed avalanche initiation range under 1.0 mA test current |
| VWM | 81.0 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | 144 V @ 4.3 A - clamped voltage during 10/1000 µs surge, limiting downstream IC stress |
| PPPSM | 600 W - non-repetitive peak pulse power handling capability per standard waveform |
| TJ max | +150 °C - maximum junction temperature enabling under-hood automotive deployment |
| RθJA | 55 °C/W - thermal resistance from junction to ambient, critical for PCB copper area design |
| MSL Level | Level 1 per J-STD-020 - no floor life limitation; safe for standard SMT reflow without dry pack |
Pinout & Package
Package: DO-214AA (SMB), surface-mount, cathode band marked on case. Bidirectional configuration means both terminals are symmetrical; polarity marking indicates cathode for unidirectional variants only - not applicable to P6SMB100CH.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals function identically in bidirectional mode; connects across protected line and ground or differential pair |
| Cathode band (not used) | Marking indicator | Not functional for P6SMB100CH; present only for unidirectional variants (e.g., P6SMB100H) |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including temperature cycling, HTRB, and ESD robustness per JEDEC standards |
| Glass-passivated junction | Ensures long-term stability of VBR and low leakage drift over lifetime and thermal stress |
| ISO 7637-2 compliance | Guaranteed clamping performance across Pulse 1 (inductive switch-off), Pulse 2a/2b (battery disconnect/load dump), and Pulse 3a/3b (EFT) |
| Low-profile SMB package | Enables automated placement and high-density PCB layouts while maintaining 600 W surge rating |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for environmentally restricted materials |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V vehicle power rails from load-dump spikes and alternator transients. IC Role / Device Role: Bidirectional TVS placed between battery rail and ground to clamp ±100 V surges. Use Value: Limits voltage seen by MCU power supply and CAN transceivers to ≤144 V, preventing latch-up or permanent damage. | Use Scenario: Safeguarding analog sensor inputs (e.g., pressure, temperature) in factory automation systems exposed to relay switching noise. IC Role / Device Role: TVS connected across differential signal lines or from signal to ground to absorb EFT bursts. Use Value: Maintains signal integrity by clamping transients before they exceed ADC input absolute maximum ratings (e.g., ±15 V). |
| LED Lighting Driver Protection | Telecom DC Power Input Protection |
Use Scenario: Shielding constant-current LED drivers from inductive kickback when driving solenoids or relays on shared PCBs. IC Role / Device Role: TVS placed across driver output or supply input to divert energy from MOSFET switching edges. Use Value: Prevents gate oxide failure in driver FETs by suppressing >100 V spikes within <1 ps, preserving driver lifetime. | Use Scenario: Securing -48 V telecom power feeds against lightning-induced surges and hot-swap transients. IC Role / Device Role: Bidirectional TVS installed at board edge between -48 V rail and return, rated for negative/positive excursions. Use Value: Clamps both polarities to ≤144 V, ensuring downstream DC/DC converters survive ±200 V transients per ITU-T K.20. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | Same DO-214AA package, identical 90–110 V VBR, but lower 100 W PPPSM rating (vs. 600 W) | Not suitable for ISO 7637-2 Pulse 1 or 2b; limited to low-energy ESD/EFT only | Select P6SMB100CH where full 600 W automotive surge immunity is required. |
| 1.5KE100CA | Higher 1.5 kW PPPSM, but axial DO-15 package - incompatible with SMT assembly and space-constrained layouts | Requires through-hole mounting and larger PCB real estate; unsuitable for high-volume automated production | Choose P6SMB100CH for surface-mount compatibility, MSL 1 handling, and automotive qualification. |
Compared with SMBJ100CA and 1.5KE100CA, P6SMB100CH uniquely delivers 600 W surge capability in an AEC-Q101-qualified, MSL 1, SMT-ready DO-214AA package - making it the only option satisfying automotive-grade transient immunity, automated assembly, and board-space constraints simultaneously.

FAQ
What does the "CH" suffix indicate in P6SMB100CH?
The "CH" suffix denotes a bidirectional configuration - meaning the P6SMB100CH provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., P6SMB100H), it has no cathode marking and functions identically across both terminals, making it ideal for AC-coupled lines or differential bus protection where polarity reversal may occur.
Is P6SMB100CH suitable for automotive applications?
Yes, P6SMB100CH is AEC-Q101 qualified and explicitly tested to meet ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b requirements. Its 600 W peak pulse power rating, 150 °C maximum junction temperature, and MSL 1 rating confirm suitability for under-hood and body-control module deployments where reliability under thermal and electrical stress is mandatory.
What is the clamping voltage of P6SMB100CH and why does it matter?
The clamping voltage of P6SMB100CH is 144 V at 4.3 A peak pulse current (10/1000 µs waveform). This value determines the maximum voltage imposed on downstream circuitry during a surge event. A lower VC would offer tighter protection, but P6SMB100CH balances robust energy handling (600 W) with controlled clamping - essential for safeguarding 100 V-rated capacitors and 150 V MOSFETs in automotive power stages.
How does P6SMB100CH differ from P6SMB100AH?
P6SMB100AH has a tighter VBR range (95–105 V) versus P6SMB100CH (90–110 V), resulting in higher minimum breakdown and slightly improved noise margin. However, P6SMB100CH offers broader tolerance for manufacturing variation and temperature drift, while both share identical packaging, clamping (144 V), and surge rating (600 W). Selection depends on system-level VBR margin requirements.
Can P6SMB100CH be used in place of a unidirectional TVS like P6SMB100H?
No - P6SMB100CH is bidirectional and lacks polarity marking, whereas P6SMB100H is unidirectional with a defined cathode band. Substituting P6SMB100CH for P6SMB100H in DC circuits with asymmetric voltage stress (e.g., single-rail bias) may allow unintended conduction during normal operation. Always verify circuit topology: use P6SMB100CH only where symmetrical transient suppression is required.
