Overview
P6SMB13CAHE3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 13 V standoff voltage (VWM), 18.2 V clamping voltage (VC) at 33.0 A peak pulse current, and 600 W peak pulse power with 10/1000 μs waveform - deployed for ESD and surge protection on signal lines of automotive sensor units and industrial I/O interfaces.
For engineers reviewing the P6SMB13CAHE3/5B datasheet, P6SMB13CAHE3/5B pinout, P6SMB13CAHE3/5B application, or P6SMB13CAHE3/5B equivalent, key selection criteria include bidirectional clamping behavior, AEC-Q101 qualification, 13 V stand-off rating, low thermal resistance (RθJL = 20 °C/W), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a voltage-clamped transient protector with symmetrical breakdown in both polarities due to its bidirectional construction. It exhibits a 12.4 V to 13.7 V breakdown voltage (VBR) at 1 mA test current and maintains ≤1.0 μA reverse leakage at 11.1 V stand-off voltage.
Designed for repetitive surge events at 0.01% duty cycle, it delivers fast response time (<1 ns), low incremental surge resistance, and meets J-STD-020 MSL Level 1 with 260 °C reflow peak. Its glass-passivated junction ensures stable performance across -65 °C to +150 °C operating junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 11.1 V - maximum continuous reverse voltage before clamping initiates; defines safe operating margin for 12 V nominal systems. |
| VBR (Breakdown) | 12.4 V to 13.7 V at 1 mA - guaranteed conduction threshold ensuring predictable turn-on during transients. |
| VC (Clamping) | 18.2 V at 33.0 A - limits downstream voltage stress during 10/1000 μs surge, protecting 15 V-rated ICs. |
| PPPM | 600 W - peak pulse power handling capability under standardized 10/1000 μs waveform, enabling robust lightning/inductive-spike immunity. |
| TJ max. | +150 °C - maximum junction temperature allowing reliable operation in under-hood automotive and high-ambient industrial environments. |
| RθJL | 20 °C/W - low junction-to-lead thermal resistance supports efficient heat transfer to PCB copper, critical for sustained surge duty cycles. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock per AEC specification. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13CA | Same VWM (11.1 V), lower PPPM (400 W), SMA package (DO-214AC), RθJA = 140 °C/W | Limited to lower-energy transients; less suitable for automotive load-dump or industrial 4 kV surges. | Select when cost or board space is prioritized over 600 W surge headroom and AEC-Q101 compliance. |
| 1.5KE13CA | Through-hole TO-204AA (DO-41), same VWM/VC, PPPM = 1500 W, higher mounting thermal resistance | Requires through-hole assembly; incompatible with fully SMT production; better for prototyping or legacy repair. | Choose only if manual assembly or legacy footprint compatibility is required - not recommended for new SMT designs. |
Compared with SMAJ13CA and 1.5KE13CA, P6SMB13CAHE3/5B uniquely combines AEC-Q101 qualification, 600 W SMT-rated surge capacity, and SMB package compatibility - making it the preferred choice for volume automotive and industrial applications demanding zero rework risk and full process automation.

FAQ
What is the clamping voltage of P6SMB13CAHE3/5B at its rated peak pulse current?
The P6SMB13CAHE3/5B has a maximum clamping voltage (VC) of 18.2 V at 33.0 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88370 and ensures downstream circuitry remains within safe voltage limits during surge events. The P6SMB13CAHE3/5B achieves this with minimal voltage overshoot due to its low incremental surge resistance and fast sub-nanosecond response.
Is P6SMB13CAHE3/5B suitable for automotive applications?
Yes, P6SMB13CAHE3/5B is AEC-Q101 qualified and designated with the "HE3" suffix indicating RoHS-compliant and automotive-grade reliability. It undergoes stress testing for temperature cycling, humidity bias, and mechanical shock per AEC-Q101 Rev D. The P6SMB13CAHE3/5B is explicitly recommended for engine control units, body electronics, and ADAS sensor interfaces where field failure is unacceptable.
What does the "CA" suffix mean in P6SMB13CAHE3/5B?
The "CA" suffix in P6SMB13CAHE3/5B denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities, with identical VBR, VWM, and VC characteristics regardless of voltage polarity. Unlike unidirectional variants (e.g., P6SMB13A), the P6SMB13CAHE3/5B has no cathode band marking and is used where AC signals, floating references, or polarity-agnostic protection are required.
What is the thermal resistance from junction to lead for P6SMB13CAHE3/5B?
The P6SMB13CAHE3/5B has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, as specified in the Thermal Characteristics table of Vishay document 88370. This low value enables effective heat dissipation into PCB copper pads during repetitive surge events. When mounted on the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, the P6SMB13CAHE3/5B maintains safe junction temperatures even under 0.01% duty cycle operation.
How does the "HE3/5B" ordering code affect P6SMB13CAHE3/5B packaging and compliance?
The "HE3/5B" suffix indicates RoHS-compliant, AEC-Q101 qualified construction (HE3) supplied in 13" diameter plastic tape and reel (5B) with 3200 units per reel. This differs from "E3/52" (7" reel, 750 units) and confirms the P6SMB13CAHE3/5B meets automotive material requirements including whisker resistance (JESD 201 Class 2) and lead-free solder compatibility up to 260 °C peak reflow temperature.
