Product details
Overview
P6SMB160CH from Taiwan Semiconductor is a bidirectional 600W surface-mount Transient Voltage Suppressor (TVS) diode in DO-214AA (SMB) package, with breakdown voltage range 144–176 V, clamping voltage 230 V at 2.7 A peak pulse current, and AEC-Q101 qualification for automotive-grade surge protection in power supply rails and CAN/LIN bus interfaces.
For engineers reviewing the P6SMB160CH datasheet, P6SMB160CH pinout, P6SMB160CH application, or P6SMB160CH equivalent, this page delivers verified electrical specs, thermal performance data, ISO 7637-2 compliance details, junction capacitance behavior, and real-world design guidance for ESD and load-dump transient suppression in automotive electronics.
Technical Context
The P6SMB160CH is a unidirectional/bidirectional TVS diode designed for high-energy transient suppression using an avalanche breakdown mechanism. Its glass-passivated junction ensures stable VBR and low leakage (<1 µA @ 130 V), while fast response time (<1.0 ps) enables protection against EFT and ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
Thermal performance is defined by RθJC = 10 °C/W and RθJA = 55 °C/W, supporting operation from –55 °C to +150 °C. It meets JESD201 Class 2 whisker resistance and moisture sensitivity level 1 per J-STD-020, enabling reliable reflow soldering in automated SMT lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 144 V / 176 V - defines minimum and maximum voltage at which avalanche conduction begins under 1 mA test current; critical for ensuring clamping occurs above normal operating rail. |
| VWM | 130 V - maximum continuous reverse working voltage; system must operate ≤130 V DC to avoid leakage-induced power loss or thermal stress. |
| VC @ IPPM | 230 V at 2.7 A - clamped voltage during 10/1000 µs surge; determines maximum stress imposed on downstream ICs during transient events. |
| PPPSM | 600 W - non-repetitive peak pulse power rating; defines single-event surge energy handling capacity without failure. |
| IPPM | 2.7 A - peak pulse current at VC; used with PCB trace impedance and source impedance to estimate actual clamping margin. |
| TJ max | +150 °C - maximum junction temperature; sets thermal derating limit for sustained surge duty cycles or ambient temperature design margins. |
| Capacitance (CJ) | ~10 pF @ 0 V - low junction capacitance minimizes signal distortion in high-speed data lines like CAN FD or LIN. |
Pinout & Package
Package: DO-214AA (SMB), surface-mount, molded plastic case with matte tin-plated leads, polarity indicated by cathode band (for unidirectional variants); P6SMB160CH is bidirectional - no polarity marking required.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Transient current path | Either terminal conducts during positive or negative surges; symmetric clamping behavior eliminates orientation constraints during placement. |
| Case (body) | Thermal and mechanical interface | DO-214AA body provides 10 °C/W junction-to-case thermal resistance; requires adequate copper pour for heat dissipation under repetitive surge conditions. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood and cabin applications including temperature cycling, humidity bias, and mechanical shock per AEC standard. |
| ISO 7637-2 compliant | Withstands Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (EFT) without degradation or parametric shift. |
| Glass-passivated junction | Ensures long-term stability of VBR and low IR drift over 10+ years in harsh environments; reduces risk of parametric failure in industrial deployments. |
| Moisture sensitivity level 1 | Enables direct placement from dry pack without baking; eliminates production delays and moisture-related popcorning during reflow. |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU; supports green manufacturing and end-of-life recycling requirements. |
Applications
| Automotive Power Rail Protection | CAN Bus Transient Suppression |
|---|---|
|

IC Role / Device Role: Bidirectional TVS placed between CAN_H and CAN_L, and each line to ground. Use Value: 10 pF junction capacitance avoids signal integrity degradation at 500 kbps CAN FD rates while clamping ±230 V surges. |
| Industrial Sensor Interface Protection | LIN Bus Overvoltage Guard |
|

Use Scenario: LIN transceiver nodes in automotive lighting systems exposed to battery reversal and jump-start transients. IC Role / Device Role: Bidirectional TVS on LIN bus line referenced to ground, providing symmetrical ±230 V clamping. Use Value: Fast <1 ps response ensures clamping initiates before LIN transceiver internal ESD structures fail during 100 ns rise-time spikes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160A | Unidirectional only; VC = 259 V @ 2.3 A; lower PPPM (400 W); same DO-214AC (SMA) package but smaller thermal mass. | Requires correct polarity placement; less robust for bidirectional surges like EFT or AC-coupled noise. | Select when cost-sensitive designs accept unidirectional limitation and lower surge margin. |
| 1.5KE160CA | Through-hole TO-218; VC = 252 V @ 3.2 A; higher PPPM (1500 W); larger footprint and manual assembly required. | Better suited for high-energy industrial mains coupling; incompatible with SMT-only production flows. | Choose when legacy board redesign permits through-hole use and >600 W surge headroom is mandatory. |
Compared with SMAJ160A and 1.5KE160CA, the P6SMB160CH uniquely combines bidirectional capability, AEC-Q101 qualification, SMB package compatibility with automated SMT lines, and precise 230 V clamping-making it optimal for new automotive and industrial PCB designs requiring zero-polarity-placement overhead and ISO 7637-2 compliance.

FAQ
What is the polarity configuration of P6SMB160CH?
The P6SMB160CH is a bidirectional TVS diode, meaning it provides symmetrical clamping for both positive- and negative-going transients without requiring orientation during PCB placement. Unlike unidirectional variants (e.g., P6SMB160H), it has no cathode band marking and functions identically regardless of terminal connection direction - a key advantage for differential bus protection like CAN or LIN.
Does P6SMB160CH meet ISO 7637-2 Pulse 5a (load dump) requirements?
The P6SMB160CH is rated for 600 W peak pulse power with a clamping voltage of 230 V at 2.7 A under 10/1000 µs waveform, which satisfies ISO 7637-2 Pulse 5a for 24 V systems where peak clamping must remain below 300 V. However, full compliance requires proper PCB layout (low-inductance grounding, short traces) and coordination with upstream fusing - the P6SMB160CH alone does not guarantee system-level certification.
What is the maximum steady-state power dissipation of P6SMB160CH?
The P6SMB160CH has a steady-state power dissipation (Ptot) of 3 W at TA = 25 °C. This rating applies only to continuous DC or low-frequency reverse-biased conditions - not transient events. In normal operation at VWM = 130 V, leakage remains <1 µA, resulting in negligible static power (<130 µW); thermal design focuses on surge duty cycle, not steady-state loading.
Can P6SMB160CH be used in place of P6SMB160AH?
No - P6SMB160CH and P6SMB160AH are distinct variants: CH denotes bidirectional construction, while AH indicates unidirectional with tighter VBR tolerance (152–168 V vs. 144–176 V). Substituting P6SMB160CH for P6SMB160AH introduces polarity-insensitive behavior and wider VBR spread, potentially affecting precision clamp timing in sensitive analog circuits; always verify circuit topology before interchange.
What is the junction capacitance of P6SMB160CH and how does it affect high-speed data lines?
The P6SMB160CH exhibits ~10 pF junction capacitance at 0 V bias (measured at 1 MHz), rising slightly near VWM. This low value ensures minimal signal attenuation or timing skew on CAN FD (up to 2 Mbps) and LIN (20 kbps) buses. For USB or Ethernet, however, even 10 pF may degrade eye diagrams - P6SMB160CH is not recommended for those interfaces without empirical validation.
